The document is a seminar report on floods submitted by Ankit Kalaraya that discusses the causes, effects, and management of floods. It covers natural causes like intense rainfall and man-made causes such as bank erosion. Examples of effects include physical damage, disruption of essential services, and long term impacts. The report also provides a case study on devastating floods in Uttarakhand, India in 2013.
this presentation gives a brief about what are the different types of floods depending upon area & its cause.It is further aided with mitigation or management techniques to be implemented & types of damages.
Irrigation system of Pakistan proved at top level of countries in the world but still it need deep concern regarding to control flood water. Due to heavy rainfall in September 2011, floods are come in left bank of drain and it has many impacts on the various cities and villages of sindh were observed, at least 360 people were killed, some 5.35 Million people and 1.2 Million homes affected as well 1.7 Million Acres of arable land inundated. Social life was fully disturbed as economy was destroyed due to damage of crop, people were also suffering from drinking water which was not purely provided and due to this dirty water many of the diseases were appeared like direa, malaria and tified. In this research we measure the losses during heavy rain fall 2011 in Nawabshah, Sh Benazeerabad regarding to impact on our social lives and then its precautions in future planning. Data was collected from social survey in premises of city, different departments including NGO’s and Governmental Departments and also solutions on immediate basis are discussed.

The disaster management and the details about the floods that occurred in Chennai City in the month of November-December 2015 were clearly discussed in the presentation.
India is a country of Disasters. We are looking into Disaster Management as a basic problem of India. Our own work in the field of Earthquakes is also discussed.

Primarily all floods are due to the surface runoff. Actually the floods are the results of a favourable combination of precipitation and the characteristics of the water shed.
Do you think the occurrence of Flood is lethal? A flood is an overflow of water that submerges usually dry land. Floods can also occur in rivers when the flow rate exceeds the capacity of the river channel, particularly at bends or meanders in the waterway. Floods often cause damage to homes and businesses if they are in the natural flood plains of rivers. Flooding is simply the result of a powerful weather system, but certain human activities can exacerbate the chances of flooding and make it worse when it occurs. Urban development, agriculture, and deforestation require careful management to keep such natural disasters from occurring. Causes of floods include hurricanes, broken levees or dams, rapidly thawing snow, and heavy slow-moving rain or repeated rains.

Hybrid optimization of pumped hydro system and solar- Engr. Abdul-Azeez.pdffxintegritypublishin
Advancements in technology unveil a myriad of electrical and electronic breakthroughs geared towards efficiently harnessing limited resources to meet human energy demands. The optimization of hybrid solar PV panels and pumped hydro energy supply systems plays a pivotal role in utilizing natural resources effectively. This initiative not only benefits humanity but also fosters environmental sustainability. The study investigated the design optimization of these hybrid systems, focusing on understanding solar radiation patterns, identifying geographical influences on solar radiation, formulating a mathematical model for system optimization, and determining the optimal configuration of PV panels and pumped hydro storage. Through a comparative analysis approach and eight weeks of data collection, the study addressed key research questions related to solar radiation patterns and optimal system design. The findings highlighted regions with heightened solar radiation levels, showcasing substantial potential for power generation and emphasizing the system's efficiency. Optimizing system design significantly boosted power generation, promoted renewable energy utilization, and enhanced energy storage capacity. The study underscored the benefits of optimizing hybrid solar PV panels and pumped hydro energy supply systems for sustainable energy usage. Optimizing the design of solar PV panels and pumped hydro energy supply systems as examined across diverse climatic conditions in a developing country, not only enhances power generation but also improves the integration of renewable energy sources and boosts energy storage capacities, particularly beneficial for less economically prosperous regions. Additionally, the study provides valuable insights for advancing energy research in economically viable areas. Recommendations included conducting site-specific assessments, utilizing advanced modeling tools, implementing regular maintenance protocols, and enhancing communication among system components.

5. Introduction
• Flood is overflow of excess water that submerges
land and inflow of tide onto land
• The flood is the result of runoff from rainfall and /or
melting snow in quantities too great to be confined in
the low water channels of streams
• A flood is usually caused by rain, heavy
thunderstorms, and thawing of snow
6. Causes of flood
Natural
• Intensity of rainfall
• Topography of the catchment
• Obstruction in river flow
• Sedimentation of rivers
• earthquake
• Contraction of river
Man-made
• Bank erosion
• failure of Dam
• Failure of river embankment
7. Causes of flood
Intensityof rainfall
• Whenever there is heavy precipitation over the catchment
in terms of intensity, duration and spread, the river will
carry high flow and thus results into flood.
• The intensity of rainfall in the catchment area is the main
cause of flood.
Topographyof the catchment
• Larger the size of the catchment more will be the flood.
• The catchment area with steep slope increases the run off
and also the sediment inflow due to high velocity of flow.
Obstructionin river flow
• Whenever there is heavy landslide in the river it may cause
flood on the u/s side due to arrest of flow and
consequently rise in the water level.
8. Sedimentation of rivers
• If the tributaries of the river carry heavy sediment load the
river bed goes on silting up gradually every year.
• It will affect the carrying capacity of the river.
Contractionofriver
• Inadequatewaterway at rail and road crossing will
affect river flow.
• While constructing road or railway bridges across a
river, the approach works are done on both bank
which reduce c/s of the river

• Economic and Social Disruption
• Increase in Air / Water Pollution
`Typeof flood
1 Coastal Flood
2 River Flood
3 Flash Flood
12. 1 CoastalFlood
- Low-lying coastal land are more prone to coastal
floods
- Caused by Intense Storms such as tropical storms and
tropical cyclones
- Tropical cyclones are also known as hurricanes
- Strong winds during these storms generate large
waves known as storm surge
- Storm surges can bring about higher water level and
cause coastal floods
2 RiverFlood
• Sudden increase in river’s flow (water)
• Water overflows the banks
• Leads to deposit of sediments on floodplains
• Caused by snowmelt, heavy rainfall, dam failure, etc.
13. 3 FlashFlood
• Sudden floods, lasts for a short duration.
• Caused by sudden and heavy rainfall.
• Can also be caused by Coastal and River floods.
Flood management
• Hard engineering
• (Structural)
• Soft engineering
• (Non-structural)
• Embankments
• Dams & reservoirs
• Channel improvement
• Drainage improvement
• Diversionof floodrivers
• Flood plain zoning
• Flood preparedness
• Flood forecasting
• Afforestation
• Public relief
16. Conclusion
Although flood is the most deadliest disaster still, but it
has some benefits like:
• Recharges ground water
• Fresh water flood help in maintaining food plain
ecosystem
• Boost in food production for birds
• Facilitation of weather fish to new habitat

From 14 to 17 June 2013, Indianstate of Uttarakhandand
near by received heavy rainfall.
The rainfall was above benchmark which is above 375
percent.
A multi-day cloudburst ,centered on the state
Uttarakhandcaused devastating floods and landslides.
Due to Continuous Rain the Chorabari Glacier melted and
this triggered the flooding of the Mandakiniriver which
led to heavy floods near Gobindghat, KedarDome,
Rudraprayag district, Uttarakhand.
