The document summarizes research on changes to sediment flow in the Pamba River in Kerala, India induced by dams constructed along the river. Eleven dams have been built on the Pamba River and its tributaries for hydroelectric, water supply, and irrigation projects. Analysis of sediment load and discharge data from three gauging stations on the river from before and after dam construction shows that the dams have significantly impacted the flow of sediments through the river by slowing or stopping sediment movement downstream. In particular, the dams prevent the natural movement of sediment and disrupt the river's morphological equilibrium between sediment inflow and outflow.

Environmental Qualitative assessment of rivers sedimentsGJESM Publication
In this study, the concentrations of heavy metals (Ca, Zn, Cu, Fe, Mn, Ni) in thesediment of Shavoor River in Khuzestan Province in Iran has been investigated. After the library studies and field studies, six samples of water
and sediment were taken from the river in order to evaluate heavy metal pollution in sediments. To determine the
geochemical phases of metals in sediment samples the 5-step method was used for chemical separation. For quantitative assessment of the severity of contamination in the sediments, the geochemical indicators such as enriched factor (EF) and the accumulation index (Igeo) were used. Also, the statistical analyses including methods such as correlation analysis cluster analysis the (CA), were conducted.The results of the experiments showed that the organic matter deposited varies
with the average of 2.49 and ranges between 1.95% and 3.43%. Samples showed concentrations of metals such as calcium, iron, manganese, copper and nickel at all the sampling points were below the global average, whereas the concentration of copper was slightly higher than the global scale. Enriched factor (EF) was calculated for the elements revealed that heavy metals are classified as non-infected. The Geo-accumulation Index showed that the studied elements were uninfected peers. Based on the results of multivariate statistical analysis it was concluded that metals such as manganese, copper, iron, nickel and zinc are mainly natural and calcium metal is likely to have an organic origin.

Sediment Source and Transport in River Channels: Implications for River Struc...theijes
Rivers are important resources that play the role of life sustenance in nature by providing environmental, cultural and economic benefits including municipal water use, irrigation, hydropower, navigation, fishing and recreation. Since they are the corridors connecting terrestrial environment to the ocean realm, they always transport and accumulate sediments. Knowledge and understanding of sediment characteristics, channel processes, process of sediment source and transport in river channels is vital in modeling and managing rivers in terms of how they both transport and impact engineering structures erected on rivers. Although, ongoing research is beginning to fill in some of these gaps through the use of laboratory experiments and mathematical models, this has not been matched by sufficient progress in measuring and quantifying the bifurcation process in natural river channels, very often because natural rivers are far harder to study and the technology required still remains unavailable. When the rate of sediment influx is high along river channels, reservoirs in dams are filled up with sediment which might need dredging to remove the sediments. Also turbine blades of power plants are considerably disturbed as a result of sediment particles deposited on the blades; flow in culverts and around bridge piers are exposed to erosion of the bed thereby exposing the foundation. Problems arising from sediment transport and deposition can be mitigated by selecting suitable cross sections for the measurement of sediment flow rate parameters and removal of the sediment which would lead to the reduction of negative impacts on the river structures.

BROAD UNEXPOSED SKILLS OF TRANSGENDER ENTREPRENEURSIAEME Publication
Since ages gender difference is always a debatable theme whether caused by nature, evolution or environment. The birth of a transgender is dreadful not only for the child but also for their parents. The pain of living in the wrong physique and treated as second class victimized citizen is outrageous and fully harboured with vicious baseless negative scruples. For so long, social exclusion had perpetuated inequality and deprivation experiencing ingrained malign stigma and besieged victims of crime or violence across their life spans. They are pushed into the murky way of life with a source of eternal disgust, bereft sexual potency and perennial fear. Although they are highly visible but very little is known about them. The common public needs to comprehend the ravaged arrogance on these insensitive souls and assist in integrating them into the mainstream by offering equal opportunity, treat with humanity and respect their dignity. Entrepreneurship in the current age is endorsing the gender fairness movement. Unstable careers and economic inadequacy had inclined one of the gender variant people called Transgender to become entrepreneurs. These tiny budding entrepreneurs resulted in economic transition by means of employment, free from the clutches of stereotype jobs, raised standard of living and handful of financial empowerment. Besides all these inhibitions, they were able to witness a platform for skill set development that ignited them to enter into entrepreneurial domain. This paper epitomizes skill sets involved in trans-entrepreneurs of Thoothukudi Municipal Corporation of Tamil Nadu State and is a groundbreaking determination to sightsee various skills incorporated and the impact on entrepreneurship.

A STUDY ON THE IMPACT OF ORGANIZATIONAL CULTURE ON THE EFFECTIVENESS OF PERFO...IAEME Publication
The main objective of this study is to analyze the impact of aspects of Organizational Culture on the Effectiveness of the Performance Management System (PMS) in the Health Care Organization at Thanjavur. Organizational Culture and PMS play a crucial role in present-day organizations in achieving their objectives. PMS needs employees’ cooperation to achieve its intended objectives. Employees' cooperation depends upon the organization’s culture. The present study uses exploratory research to examine the relationship between the Organization's culture and the Effectiveness of the Performance Management System. The study uses a Structured Questionnaire to collect the primary data. For this study, Thirty-six non-clinical employees were selected from twelve randomly selected Health Care organizations at Thanjavur. Thirty-two fully completed questionnaires were received.
Living in 21st century in itself reminds all of us the necessity of police and its administration. As more and more we are entering into the modern society and culture, the more we require the services of the so called ‘Khaki Worthy’ men i.e., the police personnel. Whether we talk of Indian police or the other nation’s police, they all have the same recognition as they have in India. But as already mentioned, their services and requirements are different after the like 26th November, 2008 incidents, where they without saving their own lives has sacrificed themselves without any hitch and without caring about their respective family members and wards. In other words, they are like our heroes and mentors who can guide us from the darkness of fear, militancy, corruption and other dark sides of life and so on. Now the question arises, if Gandhi would have been alive today, what would have been his reaction/opinion to the police and its functioning? Would he have some thing different in his mind now what he had been in his mind before the partition or would he be going to start some Satyagraha in the form of some improvement in the functioning of the police administration? Really these questions or rather night mares can come to any one’s mind, when there is too much confusion is prevailing in our minds, when there is too much corruption in the society and when the polices working is also in the questioning because of one or the other case throughout the India. It is matter of great concern that we have to thing over our administration and our practical approach because the police personals are also like us, they are part and parcel of our society and among one of us, so why we all are pin pointing towards them.
A STUDY ON TALENT MANAGEMENT AND ITS IMPACT ON EMPLOYEE RETENTION IN SELECTED...IAEME Publication
The goal of this study was to see how talent management affected employee retention in the selected IT organizations in Chennai. The fundamental issue was the difficulty to attract, hire, and retain talented personnel who perform well and the gap between supply and demand of talent acquisition and retaining them within the firms. The study's main goals were to determine the impact of talent management on employee retention in IT companies in Chennai, investigate talent management strategies that IT companies could use to improve talent acquisition, performance management, career planning and formulate retention strategies that the IT firms could use. The respondents were given a structured close-ended questionnaire with the 5 Point Likert Scale as part of the study's quantitative research design. The target population consisted of 289 IT professionals. The questionnaires were distributed and collected by the researcher directly. The Statistical Package for Social Sciences (SPSS) was used to collect and analyse the questionnaire responses. Hypotheses that were formulated for the various areas of the study were tested using a variety of statistical tests. The key findings of the study suggested that talent management had an impact on employee retention. The studies also found that there is a clear link between the implementation of talent management and retention measures. Management should provide enough training and development for employees, clarify job responsibilities, provide adequate remuneration packages, and recognise employees for exceptional performance.
ATTRITION IN THE IT INDUSTRY DURING COVID-19 PANDEMIC: LINKING EMOTIONAL INTE...IAEME Publication
Globally, Millions of dollars were spent by the organizations for employing skilled Information Technology (IT) professionals. It is costly to replace unskilled employees with IT professionals possessing technical skills and competencies that aid in interconnecting the business processes. The organization’s employment tactics were forced to alter by globalization along with technological innovations as they consistently diminish to remain lean, outsource to concentrate on core competencies along with restructuring/reallocate personnel to gather efficiency. As other jobs, organizations or professions have become reasonably more appropriate in a shifting employment landscape, the above alterations trigger both involuntary as well as voluntary turnover. The employee view on jobs is also afflicted by the COVID-19 pandemic along with the employee-driven labour market. So, having effective strategies is necessary to tackle the withdrawal rate of employees. By associating Emotional Intelligence (EI) along with Talent Management (TM) in the IT industry, the rise in attrition rate was analyzed in this study. Only 303 respondents were collected out of 350 participants to whom questionnaires were distributed. From the employees of IT organizations located in Bangalore (India), the data were congregated. A simple random sampling methodology was employed to congregate data as of the respondents. Generating the hypothesis along with testing is eventuated. The effect of EI and TM along with regression analysis between TM and EI was analyzed. The outcomes indicated that employee and Organizational Performance (OP) were elevated by effective EI along with TM.
INFLUENCE OF TALENT MANAGEMENT PRACTICES ON ORGANIZATIONAL PERFORMANCE A STUD...IAEME Publication
By implementing talent management strategy, organizations would have the option to retain their skilled professionals while additionally working on their overall performance. It is the course of appropriately utilizing the ideal individuals, setting them up for future top positions, exploring and dealing with their performance, and holding them back from leaving the organization. It is employee performance that determines the success of every organization. The firm quickly obtains an upper hand over its rivals in the event that its employees having particular skills that cannot be duplicated by the competitors. Thus, firms are centred on creating successful talent management practices and processes to deal with the unique human resources. Firms are additionally endeavouring to keep their top/key staff since on the off chance that they leave; the whole store of information leaves the firm's hands. The study's objective was to determine the impact of talent management on organizational performance among the selected IT organizations in Chennai. The study recommends that talent management limitedly affects performance. On the off chance that this talent is appropriately management and implemented properly, organizations might benefit as much as possible from their maintained assets to support development and productivity, both monetarily and non-monetarily.
A STUDY OF VARIOUS TYPES OF LOANS OF SELECTED PUBLIC AND PRIVATE SECTOR BANKS...IAEME Publication
Banking regulations act of India, 1949 defines banking as “acceptance of deposits for the purpose of lending or investment from the public, repayment on demand or otherwise and withdrawable through cheques, drafts order or otherwise”, the major participants of the Indian financial system are commercial banks, the financial institution encompassing term lending institutions. Investments institutions, specialized financial institution and the state level development banks, non banking financial companies (NBFC) and other market intermediaries such has the stock brokers and money lenders are among the oldest of the certain variants of NBFC and the oldest market participants. The asset quality of banks is one of the most important indicators of their financial health. The Indian banking sector has been facing severe problems of increasing Non- Performing Assets (NPAs). The NPAs growth directly and indirectly affects the quality of assets and profitability of banks. It also shows the efficiency of banks credit risk management and the recovery effectiveness. NPA do not generate any income, whereas, the bank is required to make provisions for such as assets that why is a double edge weapon. This paper outlines the concept of quality of bank loans of different types like Housing, Agriculture and MSME loans in state Haryana of selected public and private sector banks. This study is highlighting problems associated with the role of commercial bank in financing Small and Medium Scale Enterprises (SME). The overall objective of the research was to assess the effect of the financing provisions existing for the setting up and operations of MSMEs in the country and to generate recommendations for more robust financing mechanisms for successful operation of the MSMEs, in turn understanding the impact of MSME loans on financial institutions due to NPA. There are many research conducted on the topic of Non- Performing Assets (NPA) Management, concerning particular bank, comparative study of public and private banks etc. In this paper the researcher is considering the aggregate data of selected public sector and private sector banks and attempts to compare the NPA of Housing, Agriculture and MSME loans in state Haryana of public and private sector banks. The tools used in the study are average and Anova test and variance. The findings reveal that NPA is common problem for both public and private sector banks and is associated with all types of loans either that is housing loans, agriculture loans and loans to SMES. NPAs of both public and private sector banks show the increasing trend. In 2010-11 GNPA of public and private sector were at same level it was 2% but after 2010-11 it increased in many fold and at present there is GNPA in some more than 15%. It shows the dark area of Indian banking sector.

An experiment conducted in this study found that BaSO4 changed Nylon 6's mechanical properties. By changing the weight ratios, BaSO4 was used to make Nylon 6. This Researcher looked into how hard Nylon-6/BaSO4 composites are and how well they wear. Experiments were done based on Taguchi design L9. Nylon-6/BaSO4 composites can be tested for their hardness number using a Rockwell hardness testing apparatus. On Nylon/BaSO4, the wear behavior was measured by a wear monitor, pinon-disc friction by varying reinforcement, sliding speed, and sliding distance, and the microstructure of the crack surfaces was observed by SEM. This study provides significant contributions to ultimate strength by increasing BaSO4 content up to 16% in the composites, and sliding speed contributes 72.45% to the wear rate
ROLE OF SOCIAL ENTREPRENEURSHIP IN RURAL DEVELOPMENT OF INDIA - PROBLEMS AND ...IAEME Publication
The majority of the population in India lives in villages. The village is the back bone of the country. Village or rural industries play an important role in the national economy, particularly in the rural development. Developing the rural economy is one of the key indicators towards a country’s success. Whether it be the need to look after the welfare of the farmers or invest in rural infrastructure, Governments have to ensure that rural development isn’t compromised. The economic development of our country largely depends on the progress of rural areas and the standard of living of rural masses. Village or rural industries play an important role in the national economy, particularly in the rural development. Rural entrepreneurship is based on stimulating local entrepreneurial talent and the subsequent growth of indigenous enterprises. It recognizes opportunity in the rural areas and accelerates a unique blend of resources either inside or outside of agriculture. Rural entrepreneurship brings an economic value to the rural sector by creating new methods of production, new markets, new products and generate employment opportunities thereby ensuring continuous rural development. Social Entrepreneurship has the direct and primary objective of serving the society along with the earning profits. So, social entrepreneurship is different from the economic entrepreneurship as its basic objective is not to earn profits but for providing innovative solutions to meet the society needs which are not taken care by majority of the entrepreneurs as they are in the business for profit making as a sole objective. So, the Social Entrepreneurs have the huge growth potential particularly in the developing countries like India where we have huge societal disparities in terms of the financial positions of the population. Still 22 percent of the Indian population is below the poverty line and also there is disparity among the rural & urban population in terms of families living under BPL. 25.7 percent of the rural population & 13.7 percent of the urban population is under BPL which clearly shows the disparity of the poor people in the rural and urban areas. The need to develop social entrepreneurship in agriculture is dictated by a large number of social problems. Such problems include low living standards, unemployment, and social tension. The reasons that led to the emergence of the practice of social entrepreneurship are the above factors. The research problem lays upon disclosing the importance of role of social entrepreneurship in rural development of India. The paper the tendencies of social entrepreneurship in India, to present successful examples of such business for providing recommendations how to improve situation in rural areas in terms of social entrepreneurship development. Indian government has made some steps towards development of social enterprises, social entrepreneurship, and social in- novation, but a lot remains to be improved.
OPTIMAL RECONFIGURATION OF POWER DISTRIBUTION RADIAL NETWORK USING HYBRID MET...IAEME Publication
Distribution system is a critical link between the electric power distributor and the consumers. Most of the distribution networks commonly used by the electric utility is the radial distribution network. However in this type of network, it has technical issues such as enormous power losses which affect the quality of the supply. Nowadays, the introduction of Distributed Generation (DG) units in the system help improve and support the voltage profile of the network as well as the performance of the system components through power loss mitigation. In this study network reconfiguration was done using two meta-heuristic algorithms Particle Swarm Optimization and Gravitational Search Algorithm (PSO-GSA) to enhance power quality and voltage profile in the system when simultaneously applied with the DG units. Backward/Forward Sweep Method was used in the load flow analysis and simulated using the MATLAB program. Five cases were considered in the Reconfiguration based on the contribution of DG units. The proposed method was tested using IEEE 33 bus system. Based on the results, there was a voltage profile improvement in the system from 0.9038 p.u. to 0.9594 p.u.. The integration of DG in the network also reduced power losses from 210.98 kW to 69.3963 kW. Simulated results are drawn to show the performance of each case.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

Sediment transport from northern rivers is highly influenced by the SW monsoon, whereas both the southwest and
northeast monsoons control the sediment yield of southern rivers. About 90 - 95 % of the sediment load is carried by the
monsoon river flows and few particular days in monsoon supplies bulk of the annual sediment load transported by the
rivers.
Pamba River is selected as the representative hydrologic regime for detailed studies about the sediment flow
changes that is caused by the construction of dams.
2. PAMBA RIVER
Kerala is the land of rivers and backwaters. There are 44 rivers cut across Kerala with its innumerable tributaries
and branches.The Pamaba river is the third longest river in Kerala after Periyar and Bharathappuza.
Pamba originates at Pulachimalai hill in the Peerumedu plateau in the Western Ghats at an altitude of 1650
meters and flows through Ranni,Kozenchery, Thiruvalla, Chenganoor,Kuttanadu, Karthikappally and Ambalappuza
Taluk and finally empties in to the Vembanadu lake. The river shares its northern boundary with the Manimala
river basin, while it shares the southern boundary with the Achankovil River basin. Pamba has many rivers combining it
starting from Kakkiyar, Azhuthayar, Kakkatar and Kallar all its tributaries. The length of the river is 176 Km. The total
catchment area of river basin is 2235 km2
. The basin experiences good rainfall, moderate temperature and humid
atmosphere. The SW and NE monsoon have great influence over the climatic condition. The normal daily temperature
varies from 22.60
C to 32.70
C as per IMD. Average annual rainfall varies from 2276 mm to 4275 mm.
The Pamba is considered as the Dakshina Ganga (Southern Ganges) due to its association with Kerala's Largest
Pilgrim Centre - Sabarimala.

2.3. DAM
A dam is a hydraulic structure constructed across a river to store water on the upstream side. It is an impervious
or fairly impervious barrier put across a natural stream so that the reservoir is formed. Due to the construction of dams
water level in the river at its up-stream side is very much increased and a large area may be submerged depending up on
the water spread of the reservoir so formed.

3. SEDIMENTS
Sediment is defined as fragmented material formed by physical and chemical weathering of rocks. Sediment
(sometimes called “silt” or “alluvium”) is comprised of solid particles of mineral and organic material that are
transported by water. In river systems the amount of sediment transported is controlled by both the transport capacity of
the flow and the supply of sediment
Sediment transport study includes movement of huge boulders down mountain sides, to diffusion of colloid-sized
material in groundwater systems. Transport is driven by gravity, and drag forces between the sediment and surrounding
fluid (air or water).
3.1. CLASSIFICATION OF SEDIMENTS
Sediment can be classified as 1. Deposited sediments, 2. Suspended sediments.
Deposited sediment is that found on the bed of a river or lake.
The “suspended sediment load” refers to the fine sediment that is carried in suspension and this can comprise
material picked up from the bed of the river (suspended bed material) and material washed into the river from the
surrounding land (wash load). The wash load is usually finer than the suspended bed material. In contrast, the “bed load”
comprises larger sediment particles that are transported on the bed of the river by rolling, sliding or saltation.
Suspended sediment is found in the water column where it is being transported by water movements.
Most rivers will transport sediment in each of these “load” forms, according to the flow conditions. Suspended sediment
is also referred to as suspended matter, particulate matter or suspended solids. Generally, the term suspended solids refers
to mineral + organic solids, whereas suspended sediment should be restricted to the mineral fraction of the suspended
solids load.
3.2. TYPES OF SEDIMENT TRANSPORT
Sediment transport is a direct function of water movement. During transport in a water body, sediment particles become
separated into three categories:
3.2.1. (1) Suspended material
Suspended materials include silt + clay + sand; the coarser, relatively inactive bedload and the saltation load.
Suspended load comprises sand + silt + clay-sized particles that are held in suspension because of the turbulence of the
water.
The suspended load is further divided into the wash load.
Wash load is generally considered to be the silt + clay-sized material (< 62 µm in particle diameter) and is often
referred to as “fine-grained sediment”. The wash load is mainly controlled by the supply of this material (usually by
means of erosion) to the river.
The amount of sand (>62 µm in particle size) in the suspended load is directly proportional to the turbulence and
mainly originates from erosion of the bed and banks of the river. In many rivers, suspended sediment (i.e. the mineral
fraction) forms most of the transported load.

30 – 31, December 2014, Ernakulam, India
214
3.2.2. (2) Bed load
Bed load is stony material, such as gravel and cobbles that moves by rolling along the bed of a river because it is
too heavy to be lifted into suspension by the current of the river. Bed load is especially important during periods of
extremely high discharge and in landscapes of large topographical relief, where the river gradient is steep (such as in
mountains). It is rarely important in low-lying areas.
Measurement of bed load is extremely difficult. Most bed load movement occurs during periods of high
discharge on steep gradients when the water level is high and the flow is extremely turbulent. Such conditions also cause
problems when making field measurements
3.2.3. (3) Saltation load
Saltation load is a term used by sedimentologists to describe material that is transitional between bedload and
suspended load. Saltation means “bouncing” and refers to particles that are light enough to be picked off the river bed by
turbulence but too heavy to remain in suspension and, therefore, sink back to the river bed. Saltation load is never
measured in operational hydrology.
4. FACTORSAFFECTINGRIVER’SVELOCITY
A river's velocity refers to the speed at which a river moves water through its channel. The velocity of a river is
determined by many factors, including the shape of its channel, the gradient of the slope that the river mover along, the
volume of water that the river carries and the amount of friction caused by rough edges within the riverbed.
4.1. CHANNEL SHAPE
The shape of the channel affects the velocity of a river. Around the perimeter of the river, at the sides and along
the river bed friction is created as water flows against the edges. Water flowing through a wide, deep river channel
encounters less resistance than water flowing in a narrow, shallow channel, since a smaller proportion of the total water
molecules will be slowed by the river's edges. The center of the river experiences the greatest velocity.
4.2. VOLUME
The volume of water that flows through a river within a given amount of time -- also known as the discharge --
also affects its velocity. As the volume of water in a river increases, through smaller streams flowing into it, for example,
the velocity of the river increases. An increase in water volume can also affect a river's velocity in the long term; this is
because the increasing mass of water is capable of causing more erosion, resulting in a wider, deeper river channel that
allows water to flow more freely.
4. 3. SMOOTH AND ROUGH CHANNEL
Rough river channels are those which contain a large quantity of rocks, pebbles and boulders, either at the
bottom of the river or embedded within its sides. A great deal of friction is created between water molecules and these
stones as the river flows past them; in rough channels, the resistance caused by this friction reduces the river's velocity.
In a smooth river channel, with fewer pebbles and rocks, velocity is higher as there is less friction causing energy to be
expended as it flows.
4.4. GRADIENT
The gradient of a river refers to how steep its slope is; this also has a significant effect on the velocity of a river.
When a river flows down a steep slope, the gravitational force that pulls the water downwards is stronger than it would
be on water flowing down a gentle slope, resulting in the river having a greater level of velocity.
The velocity of the flowing waters of a nearby river depends on local rainfall amounts and elevation. Scientists and
engineers define velocity as how fast an object's position changes as time passes. An object moving in a straight line, in a
river for example, has velocity equal to the distance it moves divided by the time of travel of that object. A common unit
for velocity is feet per second. By using a few tools we can calculate the velocity of a river.
5. RAINFALL IN KERALA
The major rainfall season in Kerala is from June to October (Monsoon Period).
The Kerala State, situated in the humid tropics lies between 8° 18’ and 12° 48’ N and 74° 52’ and 77° 22’ E.
Based on the topography, the state can be divided into three well-defined natural landforms: the lowlands with altitude
less than 7.5 m; midlands with altitude between 7.5 and 75m; and the highlands with altitudes greater than 75 m. The
state is a narrow strip of land with width varying from 30 km in the north and south to about 130 km in the central
region. The Western Ghats forms a continuous mountain wall on the eastern border of the state while Arabian Sea is the
margin to west.

5.1. MONSOON PERIOD (JUNE TO OCTOBER)
A major part of India (Excluding Jammu and Kashmir and South Eastern parts) gets more than 75% of rainfall
due to monsoon winds which originate in the Indian Ocean and proceed to the sub continent. The monsoon wind
advancing from south – western direction breaks up in to two distinct branches.
Bay of Bengal branch, Arabian Sea branch.
The Arabian Sea branch touches Kerala while the Bay of Bengal branch reaches the North – Eastern states of
India.
The average annual rainfall for the State is about 3000 mm. It ranges in the lowland, from 900 mm in the south
to 3500 mm in the north; in the midland, from 1400 mm to 4000mm; and in the highland, from 2500 mm to 6000 mm
(CWRDM, 1995). About 65 % of this rainfall is received during the southwest (SW) monsoon and 25 % during northeast
(NE) monsoon. However, for the southern parts, NE monsoon is active compared to the northern Kerala.
6. INFILTRATION
Infiltration may be defined as the downward movement of water from soil surface in to the soil mass .When rain
water falls on the ground, a small part of it is initially absorbed by the top thin layer of soil so as to replenish the soil –
moisture deficiency, and thereafter, excess water infiltrates downwards to join ground water. So infiltration is the entry
of water in to the soil through soil surface. Once water enters in to the soil, the process of transmission of water in to the
soil, known as percolation takes place thus removing the water from near the surface to down below.
6.1. FACTORS AFFECTING INFILTRATION
1. Condition of entry surface: Vegetation cover verses bare land
2. Permeability/Percolation characteristics of soil formation
3. Temperature.
4. Intensity and duration of rain fall
5. Movement of men and animals.
6. Change due to human activity
7. Quality of water
8. Presence of ground water table
7. RUN – OFF
The term “run – off “ is used for water that is on the “run” or in a flowing state in contrast to the water held in
depression storage and water evaporated in the atmosphere. The run off of a catchment area in any specified period is the
total quantity of water draining in to the stream or in to a reservoir in that period. This can be expressed as in centimeters
of water over a catchment or the total water in cubic meters or Hectare – meter for a given catchment. Run-off is broadly
classified in to three types. They are
1. Surface run-off
2. Sub surface run-off
3. Base flow.
8. DAM CONSTRUCTION
The construction of dams and other hydraulic structures is one of the oldest branches of engineering. Dams and
diversions are constructed and operated for a wide variety of purposes including residential, commercial, and agricultural
water supply; flood and/or debris control; and hydropower production. Regardless of their purpose, all dams trap
sediment to some degree and most alter the flood peaks and seasonal distribution of flows, thereby profoundly changing
the character and functioning of rivers. By changing flow regime and sediment load, dams can produce adjustments in
alluvial channels, the nature of which depends upon the characteristics of the original and altered flow regimes and
sediment loads.
9. ANALYSIS
The Discharge data and sediment load data from three gauging station of Central Water commission were
analyzed. The gauging stations are Kalloppara, Malakkara and Thumpamon. Out of these three, Kalloppara is the
gauging station nearer to Vembanadu lake. Then comes Malakkara and Thumbamon.
6. Proceedings of the International Conference on Emerging Trends in Engineering and Management (ICETEM14)
30 – 31, December 2014, Ernakulam, India
216
The data from Kallooppara gauging station were analyzed first. Starting from the year 1986 for Monsoon season
i.e. from June to November, the data were considered up to 2010. At first the data for each month in monsoon season for
the year 1986 were analyzed. It was found that the sediment load is more in June as the discharge increase. But the
sediment load was decreased for the month of August even though the discharge is more than in June. The reason is that
as the rain fall decreases the surface run off from the catchment area of river will decrease. But there will be base flow
which is the water that percolates down through the surface soil. The base flow will be free of sediment.
JUNE 87 –NOV 87 (Kalooppara)
But during the month of October there will be heavy rainfall which will again increase the surface runoff and
hence increase of sediment load. Then gradually the discharge and sediment load decreases as the rainfall intensity
decreases.
This is the general flow condition up to the year 2010.But the main change noted was that, there is considerable
decrease in sediment load. The rate of decrease of sediment load is more when the data analysied at an interval of four
years. I.e. after considering the data in 1992 the data checked for the year 1996. Then the change in sediment load was
considerable.
For example, for a discharge value of 300 cumec the sediment load in the year 1986 for the month of June was
0.045tons/m3
. In August it became 0.035tons/m3
. Again it increased in September to a value of 0.065tons/m3
then in
November it became 0.03tons/m3.
These values were almost same up to the year 1992. But for the year 2010 it became
0.03 tons/m3
. We can see that the quantity of sediment decreased as the years passed.
After Kallooppara the data from Malakkara gauging station were analysied. The cases were very similer to
Kalloppara.In june 1986 for a discharge of 300 cumecs, the discharge data was 0.045 tons/m3
.In August it became 0.05
tons/m3
, September it became 0.03tons/m3
.
JUNE 86 –NOV 86(Malakkara)
The analysis of data from Thumpamon gauging station also gave the same result. The sediment load is gradually
decreasing. This is mainly due to the effect of dams.
7. Proceedings of the International Conference on Emerging Trends in Engineering and Management (ICETEM14)
30 – 31, December 2014, Ernakulam, India
217
JUNE 86 –NOV 86 (Thumpamon)
But we can find that as the river crosses Kallooppara gauging station the sediment load is increasing than at
Malakkara and Thumpamon. The reason is that for any river there will be catchment area. The water reaching to the river
from the catchment area through small streams. The runoff from the catchment area will catch the loose soil particles as
sediment.
10. CONCLUSION
The effect of dams on sediment flow through rivers were studied by selecting Pamba river, using the discharge
data and sediment load data which were collected from three gauging stations namely Kallooppara, Thumpamon, and
Malakkara of Central Water commission.
This project verified how the quantity is varying after the construction of dams in this river. Considering the
year of starting of construction of dams in this river and in its tributaries, and also the year of completion of these dams
the sediment load data and discharge data were analysied graphically.
Starting from the year 1986 to 2010 the data were analyzed for the monsoon season (From June to November).
It was found that during the month of June the sediment load and discharge were more, but for the month of August
discharge was more but there was decrease in sediment load. The reason is that in August the rainfall intensity will be
less, so the surface run off will be less hence the sediment flow will be less. But there will be base flow which will
increase the discharge rate. Usually base flow will be free of sediments.
Again there was increase in discharge load as the intensity of rainfall increased hence there was increase in
sediment load also. During the month of November both discharge and sediment load were decreasing.
This is the general condition of flow. But it was found that the sediment load quantity is gradually decreasing as
years pass. When the data analyses for the year of 2010, there was about 50% reduction in sediment load than for the
year of 1986. This is mainly due to the effect of dams in this river and in its tributaries.
Out of the three gauging stations of Central Water Commission, the first one is Thumpamon. Then comes
Malakkara, and Kallooppara is nearer to Vembanadu lake. On analyzing the data graphically it was found that even
though there was decrease in sediment load quantity with years the sediment load is increasing when the flow reaching
Kallooppara gauging station. This shows that from the catchment area in that region the sediment load is more with
runoff. This may be due to the soil conditions, topography of that location, construction activities etc. In Thumpamon
more than 50% area is covered by forest. So the sediment load quantity will be less. Almost similar condition was
observed at Malakkara also. But the sediment load is more at Kallooppara. In this condition also we can observe that
there is reduction in sediment load quantity. This is mainly due to the effect of dams. Since there was a change in
sediment load observed at Kalkoppara there is scope of further study that what the causes of increasing sediment load
there are and even though there is increase in sediment load a common reduction can be observed. It also arising the need
of further experimental study during monsoon season in the catchment area.
