Determination of design discharge and environmental flow in micro-hydropower ...Daniel Ngoma
In designing micro hydropower plants capacity, the amount of water flow discharge determination is very essential in estimating the power output for the micro hydropower scheme due to the fact that in recent years there has been an increase in water demand due irrigation activities because of an increase in agriculture activities [1]. From the literature, there are several methods that are used to determine hydro turbine water flow discharge but the most widely used method is the hydrological method which is based on the formulation of flow duration curve or hydrograph for the respective river flow based on site historical and measured hydrological data.
The hydrograph represents the amount of water flow in m3/s that is available for a particular river or stream in percentage from the historical hydrological data which has been computed over a period of more than one year. From the study of Hhaynu River which is a small river in Tanzania, the computed flow results show that, 8% of the time the flow is at 2.3 m3/s while at 50% of the time the river flow was at 1.86 m3/s and at 100% of the time the water flow was at 0.60 m3/s. When determining design discharge for run-of-river schemes, provision have to be considered for environmental flow on which for the Hhaynu River this has been analysed to be 0.2 m3/s (33.3% of river base flow) which resulted to the hydro-turbine development design water flow discharge of 0.4 m3/s from the computed flow duration curve with provision for environmental flow.
The usefulness of developing flow duration curve for rivers is to determine the available water flow in a particular small river and its suitability for micro hydropower development from estimates of the amount of water flow discharge.

Geographic Analysis of Erosion Prone Areas and Soil Erosion in Panchaganga Ba...Malhari Survase
The main aim of this study is to identify erosion prone areas and nature of soil erosion in Panchaganga Basin of South Maharashtra. The region lies between 160 13”N. to 170 11”N latitude and 730 41”E. to 740 42”E longitude, comprise seven tahsils of Kolhapur District i.e. Karveer, Panhala, Shahuwadi, Hatkanagle, Shirol, Gaganbawada and Radhanagari. It covers about 45752.2sq.km area and supports 26, 11,547 populations.
For the identification of erosion prone area in the Panchaganga Basin three important components i.e. slope, stream frequency and drainage density has been considered. The SOI toposheets of 1:2,50,000 scale has been divided into 2 cm grids. The slope analysis has been calculated by employing Wentworth method. By marking the values derived from three components of each grid, the erosion proneness has computed and categorized into five distinct spatial units. Such areas ware further checked empirically through field trips. Topsoil loss due to raindrop erosion, rill erosion, formation of gullies, stream channel erosion, etc. is the nature of erosion. Deforestation, overgrazing, monsoonal rainfall of high intensity, hilly landforms, and smooth texture of soil is the major causes of erosion. The area of upper Panchaganga Basin including Radhanagari, Gaganbawada, Panhala, Shahuwadi and some part of Karveer tahsil has been facing acute problem of soil erosion. The reciprocal relationship has been found between slope and eroded areas. It needs to take due care immediately
Delineation of potential groundwater recharge zones plays a vital role in sustainable management of groundwater resources. The present study is carried out to identify the groundwater potential recharge zones in Multan, Pakistan by using Remote Sensing (RS) & Geographical Information System (GIS) for augmenting groundwater resources. In Multan district (Punjab, Pakistan), the increasing population and expansion of land use for agriculture have severely exploited the regional ground water resources. Land Use Land Cover (LULC) change is an accelerating phenomenon on the surface of earth driven by anthropogenic activities including urban expansion, deforestation, and climatic variations. Intensive pumping has resulted in a rapid decline in the level of water table as well as its quality. Better management practices and artificial recharge are needed for the development of sustainable groundwater resources. In order to address these issues Geographic information system (GIS) and Remote sensing (RS) are the most efficient methods for the identification and detection of Land Use patterns. All of these techniques are used for mapping and identification of groundwater potential analysis. This groundwater potential information will be useful for the effective identification of appropriate locations for extraction of water. This study should be done to delineate groundwater potential recharge zones by using different thematic layers that were overlaid in ArcGIS. In the overlay analysis, the weights (for various thematic layers) are allocated based on a review of published literature or by expert opinion. The assigned weights are then normalized and modified using the analytical hierarchical process (AHP). The potential recharge map thus obtained and divided into four zones (poor, moderate, good, and very good) based on their influence to groundwater recharge.

From three different sources viz. survey of India topographic map (1:50,000), CartoDEM (10 mts) and Aster GDEM (30 mts) morphometric parameters are derived and evaluated. Manually digitized the drainage network from toposheets and extracted drainage network system from CartoDEM and Aster GDEM using ArcGIS 10.2 software. Basic, derived and shape parameters are considered for basin analysis. The mean bifurcation ratio of the given basin for CartoDEM & Aster GDEM are having nearby values and also indicates some sort of geological control, high stream frequency (Fs) is indicative of high relief and low infiltration capacity of the bedrock pointing towards the increase in stream population with respect to increase in drainage density, low drainage density (Dd) leads to coarse drainage texture, value of Lg for topographic, CartoDEM and Aster GDEM data indicating very fine texture & fine texture respectively. From the shape parameters the Kumudvathi watershed indicates it is sub-circular and elongated. The results from the high resolution data will have the nearby values and less of % variation, whereas in low resolution data % of variation is more and will not meet criteria.

"Understanding the Carbon Cycle: Processes, Human Impacts, and Strategies for...MMariSelvam4
The carbon cycle is a critical component of Earth's environmental system, governing the movement and transformation of carbon through various reservoirs, including the atmosphere, oceans, soil, and living organisms. This complex cycle involves several key processes such as photosynthesis, respiration, decomposition, and carbon sequestration, each contributing to the regulation of carbon levels on the planet.
Human activities, particularly fossil fuel combustion and deforestation, have significantly altered the natural carbon cycle, leading to increased atmospheric carbon dioxide concentrations and driving climate change. Understanding the intricacies of the carbon cycle is essential for assessing the impacts of these changes and developing effective mitigation strategies.
By studying the carbon cycle, scientists can identify carbon sources and sinks, measure carbon fluxes, and predict future trends. This knowledge is crucial for crafting policies aimed at reducing carbon emissions, enhancing carbon storage, and promoting sustainable practices. The carbon cycle's interplay with climate systems, ecosystems, and human activities underscores its importance in maintaining a stable and healthy planet.
In-depth exploration of the carbon cycle reveals the delicate balance required to sustain life and the urgent need to address anthropogenic influences. Through research, education, and policy, we can work towards restoring equilibrium in the carbon cycle and ensuring a sustainable future for generations to come.

Abstract: The present paper deals with analysis of stream frequency and drainage density of
upper Narmada Basin in Central India. Hortan's method is used to get desired result. Stream
frequency and Drainage density are two important factors that control the speed of run off in
heavy rain. The faster runoff determines the grater density and frequency of streams. It is
observed that Upper Narmada basin has lowest drainage density indicating higher rate of
infiltration greater subsurface flow, high moisture retentive capacity and relatively low relief, and
highest drainage density indicating lower rate of infiltration and more runoff than other area,
because basin having part of rocky barren land which has less permeability that’s why in this
area groundwater table is not well developed. The highest drainage frequencies are reported
from the central, northern and eastern part of the basin, which area indicating high permeable
geology and low relief. While the lowest drainage frequencies are observed over the peripheral
part of the basin, which is having impermeable subsurface and sparse vegetation and high
relief conditions.
Key words: Drainage Density, Stream frequency, Spatial Analysis, Upper Narmada Basin
Introduction
A drainage basin is defined as an area drained by river and its tributaries. A basin is a natural
hydrological feature in which various channel, drains and streams are seen is as surface runoff.
The analysis of stream frequency and drainage density is used to manage various aspects
such as drinking water supply, observing runoff, erosion, irrigation, pollution etc. Remote
sensing and GIS techniques are important tools in the determination of morphometric analysis
of the drainage basin. It plays significant role in providing spatial data required for calculations
of morphometric indices like steam frequency and drainage density etc. The total length of
streams of all orders per drainage area is called Drainage density. Drainage density factor has
been related to climate, rocks types, relief, infiltration capacity, the cover of vegetation and
surface roughness (Horton, 1932). According to Horton (1932), Drainage Density is defined
ratio of the total length of all stream segments in a given drainage basin to the total area of that
basin. According to Horton (1932), stream frequency is the total number of stream segments of
all orders per unit area. Stream frequency is the measure of the number of streams per unit
area (Horton, 1945). A higher stream frequency indicates the higher surface runoff and steep
ground surface. Stream frequency or drainage frequency is the measure of the number of
streams per kilometer area. According to Rogers (1971), high drainage density is represented
by metamorphic rocks, whereas a sedimentary rock shows low drainage values.
Study Area
The area under “Upper Narmada Basin " comprises of a fairly large tract lying between 210
41'
North to 230
46' North latitude and from 790
17' East to 810
46' East longitude. The area comes
under the tropical belt and location of the area is itself significant. The Narmada River rises in
the Amarkantak plateau of Maikal Range in the 'Anuppur' District of Madhya Pradesh at an
elevation of 1057 meters above sea level. The river travels a distance of 1312 kms, before it
falls in to Gulf of Cambay in the Arabian Sea near Bharuch in Gujarat. The Narmada Basin
hemmed between Vindhyachal and Satpura ranges extend over and area of 98,796 kms2
. The
basin covers and large area of Madhya Pradesh (86 percent), Gujarat (14 percent) and
comparatively smaller area (2 percent) in Maharashtra. About 35 percent of the basin area in
under forest cover, 60 percent under arable land and 5 percent is grassland, wasteland etc.

Study of correction between stream frequency and drainage density.
Data Source and Methodology
To get drainage density and stream frequency, drainage map is prepared by scanning of
survey of India topographic sheets on 1:50,000 scale by Global Mapper 10.2 GIS software.
After geo referencing top sheets are compiled in single mosaic. Stream order is calculated
using Strahler (1953) system in Arc GIS 10.6 software. While the stream length, total basin
area, perimeter were measured with the help of Arc GIS 10.6 software. The entire catchment
and mainstream has been prepared from the DEM prepared by Top sheet contour and ILWIS
3.7.Hortan Method (1932) Used to get desired results. Hortan suggested stream frequency is
the dividend of numbers of streams (NU) with the area of drainage basin (A).
Stream frequency (DF) = NU/A
Whereas drainage density is the total number of stream Lengths in the basin (LU) divided by
the area of basin (A).
Drainage density (DD) = LU/A.
RESULT AND DISCUSSION
Drainage Density (DD)
The special analysis showed the drainage density is range from 0 to 6 km per sq km (Table
4.1) and the very low drainage density (0 to 1) value is attributed due to the presence of
permeable subsurface formation, dense vegetation and low relief (Langbein, 1947; Nag, 1998).
Drainage density characterizes the textural measure independent of basin size and considered
to be a function of climate, lithology, stage of development, etc. it is a measure of drainage
dissection that reflects the competing effectiveness of overland flow and infiltration. Horton
(1945) reasoned that basins of low drainage density are the product of runoff processes
dominated by infiltration and subsurface flow, whereas basins of high drainage density are the
product of erosion and dissection by overland flow. Higher drainage density also indicates the
decrease in the length of overland flow with increase in angle of hill slope (Schumm, 1956). It is
observed that Upper Narmada basin has lowest drainage density (0 to 1 km/ sq km) covers
164.59 sq. km (0.71 percent) area of the basin, indicating higher rate of infiltration greater
subsurface flow, high moisture retentive capacity and relatively low relief, and highest drainage
density (4 - 6 km/sq km) covers 4436.37 sq. km (19.21 percent) area of the basin, indicating
lower rate of infiltration and more runoff than other area, because basin having part of rocky

barren land which has less permeability that’s why in this area groundwater table is not well
developed. Table 01 shows the spatial analysis of drainage density of the Upper Narmada
basin. All these facts of the spatial analysis of Drainage density clearly indicate the
asymmetrical distribution of Drainage density of the basin.

Stream Frequency
For the computation of stream frequency, the Upper Narmada basin is conveniently divided into
the grid of one square kilometer; then the number of streams are counted in each grid of one
square kilometer and tabulated for quantification. The data of stream frequencies are classified
as a fixed Class interval as 4 streams per square kilometer area. The highest drainage
frequencies (16 to 20 Streams per sq. km) are reported from the central, northern and eastern
part of the basin, which area indicating high permeable geology and low relief. While the lowest
drainage frequencies (0 to 4 Streams per sq. km) are observed over the peripheral part of the
basin, which is having impermeable subsurface and sparse vegetation and high relief
conditions. Table 02 shows the spatial analysis of stream frequency of the Upper Narmada
basin. All these facts of the spatial analysis of stream frequency clearly indicate the
asymmetrical distribution of stream frequency of the basin.

Conclusion
It is observed that Upper Narmada basin has lowest drainage density (0 to 1 km/ sq km) covers
164.59 sq. km (0.71 percent) area of the basin, indicating higher rate of infiltration greater
subsurface flow, high moisture retentive capacity and relatively low relief, and highest drainage
density (4 - 6 km/sq km) covers 4436.37 sq. km (19.21 percent) area of the basin, indicating
lower rate of infiltration and more runoff than other area, because basin having part of rocky
barren land which has less permeability that’s why in this area groundwater table is not well
developed. The highest drainage frequencies (16 to 20 Streams per sq. km) are reported from
the central, northern and eastern part of the basin, which area indicating high permeable
geology and low relief. While the lowest drainage frequencies (0 to 4 Streams per sq. km) are
observed over the peripheral part of the basin, which is having impermeable subsurface and
sparse vegetation and high relief conditions. High Correlation is found between stream
frequency and drainage density. The High range of drainage frequency and density indicates
the mature stage of basin.
