Watershed development and management plans are more important for harnessing surface water and groundwater resources in arid and semiarid regions. To prepare a comprehensive watershed development plan, it becomes necessary to understand the topography, erosion status and drainage patterns of the region. This study was undertaken to determine the drainage characteristics of Pageru River basin using topographical maps on a scale of 1:50,000. The total area of the Pageru River basin is 480 km 2. It was divided into X sub-basins for analysis. The drainage patterns of the basin are dendritic and include a sixth order stream. The quantitative analysis of various aspects of a river basin drainage network characteristics reveals complex morphometric attributes. The streams of lower orders mostly dominate the basin. The development of stream segments in the basin area is more or less affected by rainfall. The elongated shape of the basin is mainly due to the guiding effect of thrusting and faulting. The erosional processes of fluvial origin have been predominately influenced by the subsurface lithology of the basin.

Watershed management is very crucial for arid and semi-arid regions dealing with limited availability of water resource. Morphometric assessment and prioritization studies provide basic criterion for effective local level watershed planning and natural resource management. The present study is an attempt to analyze morphometric characters of the Khari River basin and prioritize the sub-watersheds on the basis of ground water potentialities indicated by morphometric parameters using GIS approach. Khari River is semi-arid ephemeral; it is a tributary of Banas River, an important river of central Rajasthan (India). The basin has been subdivided in five sub-watersheds namely SW1 to SW5. Linear, areal, and relief parameters are calculated for Khari basin as well as for each sub-watershed. Morphometric parameters that are related to groundwater potentialities are ranked and compound factor values are calculated for each sub-watershed and priority is allotted based on these values. First priority is given to the least value of compound factor that indicate most deficit ground water condition. Overall results illustrate that Khari is a sixth-order stream and covers 6205 km 2 area. Dendritic pattern is observed in Khari and in all the five sub-watersheds that indicate homogenous nature of underlain material and less structural control in the topography. Presence of low bifurcation ratio, low drainage density, and low drainage frequency values are favorable parameters of good permeability, infiltration in the basin, further gentle slope, coarse drainage texture, moderate to low relief, and elongated shape-all these parameters indicate good groundwater potentialities in major portions of the basin. Prioritization results show that the sub-watershed SW4 is at first priority with most deficit groundwater potential in comparison to other sub-watersheds and require water conservation measures. Subwatershed SW4 has high values in linear parameters and low value in shape parameters that specify for poor groundwater potential, less permeability and high runoff, etc. Sub-watershed SW5 on contrary has indicated highest ground water potential in comparison to other sub-watersheds of the basin. The study provide local drainage morphometric information and preliminary prioritization for better water resource management in semi-arid region to achieve water self-sufficiency and sustainability at basin level.

Any hydrological study of watersheds requires morphometric analysis. This analysis is a powerful tool in watershed management (Biswas et al., 1999, Yasmin et al., 2013). Climate change coupled with land-use changes raises development issues, including the availability of water resources for people's needs. Faced with these ever-increasing needs of the population, land development becomes a requirement. Thus, the objective is to analyze the morphometric characteristics of the Sankarani basin in order to prioritize its sub-basins. To this end, the satellite images of the digital terrain model (DTM) of the SRTM (30mx30m) type of 2012 were used. Under the Grass GIS open source program, five sub-basins (BV1-I, BV2-M, BV3-Y, BV4-G and BV5-S) have been delimited. The measured parameters are the number of rivers and their classifications, to define the geometry of the basin (area, perimeter, length), the various indices (drainage density, slope ratio, texture ratio, elongation ratio and...

International Journal of Agriculture Environment & Biotechnolog, 2020
Morphometric analysis and thereby prioritization of watersheds have gained significant importance in land and water resources management. In this study an attempt has been made to prioritize sub-watersheds based on morphometric analysis using geospatial techniques in Umar Nala watershed of Narsinghpur district, of Madhya Pradesh. Morphometric parameters, considered for the present study are stream frequency (S f), drainage density (D d), texture ratio (T), elongation ratio (R e), circulatory ratio (R c), form factor (R f), bifurcation ratio (R b) and relief ratio (R h). These parameters were estimated for each sub-watershed then ranks were assigned for prioritization of sub-watersheds on the basis of value/relationship to arrive at a computed value for final ranking of the sub-watersheds. On the basis of morphometric parameters determined in GIS environment and then applying standard formulae prioritization among seventeen sub watersheds of Umar Nala, sub watershed no 10 is on top priority among seventeen sub watersheds for further soil and water conservations measures to be taken in the watershed. Highlights m This study conducted in Umar Nala watershed of Narsinghpur, district of Madhya Pradesh, India to prioritize sub-watersheds based on morphometric analysis using geospatial techniques. m In this study, we employed seventeen sub watersheds of Umar Nala, and found which watershed urgently requires soil and water conservation measures.
Quantitative Analysis of Drainage System is an Important Aspect of Prioritisation of Watersheds
2013
The quantitative analysis of drainage system is an important aspect of prioritisation of watersheds. Using watershed as a basic unit in morphometric analysis is the most logical choice because all hydrologic and geomorphic processes occur within the watershed. In the present study, an attempt has been made to study the quantitative geomorphological analysis of micro watersheds of Ghataprabha river sub-basin in Karnataka, India. The study region lies between 16° 12’ 16’’ N to 16° 30’ 1’’ N latitude and 74° 45’ 18’’ E to 75° 44’ 58’’ E longitude of northern Karnataka. The twelve micro watersheds of sub basins (KSNU032 and KSNU033) have been prioritized using GIS by determining the areal, linear, and relief parameters based on morphometric analysis on the basis of Survey of India Toposheets at 1:50,000 scale, CARTOSAT-1 DEM data, and RESOURCESAT-2 LISS-III data. Each morphometric characteristic is considered as a single parameter and knowledge based weightage has been assigned. The com...
Evaluation of Morphometric Parameter for Prioritization of Kantori Nala Milli Watershed
Current Journal of Applied Science and Technology

Abstract- Water is extremely crucial for the human being and economy of the country. Almost every industry from agriculture, hydropower and industrial manufacturing to production of readymade food and tourism relies on water to grow. Continuous population growth and economic development has significantly increased the agricultural and industrial water demand. Watershed development and management is one of solutions to such problems. To prepare a comprehensive watershed development plan, it becomes necessary to understand the topography, erosional status and drainage pattern of the area. A comprehensive study of watershed for south west Punjab region was carried out. This watershed region has the total area of approximately 4161.132 km 2. The morphometric parameters are computed by using Geographic Information system (GIS). GIS was used in evaluation of linear and aerial aspects of morphometric parameters. The drainage patterns of the basin are dendritic and include a third order str...

The morphometric analysis of the drainage basin and channel network play an important role in understanding the geo-hydrological behavior of drainage basin and expresses the prevailing climate, geology, geomorphology, structural antecedents of the catchment. Morphometric analysis of a drainage basin expresses fully the state of dynamic balance that has been attained due to dealings between matter and energy. In the present study, morphometric analysis has been carried out using Geographical Information System (GIS) techniques to assess the geo-hydrological characteristics of Vishav drainage basin and an attempt has been made to identify the ground water potential zones through geo-morphometric specs. The morphometric parameters are discussed about linear, areal and relief aspects. The basin is characterized by dendritic to sub-dendritic drainage pattern. The development of stream segments in the basin area is affected by rainfall, groundwater discharge and snow melt over. The analysis has revealed that the total number and length of stream segments is maximum in first order streams and decreases as the stream order increases. The bifurcation ratio (R b) between different successive orders varies revealing the geostructural control. The shape parameters (R c =0.52, R e =0.15 and R f =0.22) indicate the elongated shape of the basin and in association with some areal (D d , D t etc.) and relief (H, S b , etc.) parameters show that it has low discharge of runoff, generally permeable subsoil condition, moderate to high infiltration capacity and good groundwater resource and a flatter peak of flow of longer duration that is easier to manage that of the circular basins. The study reveals that morphometric analysis based on GIS technique is a competent tool for geo-hydrological studies. These studies are very useful for identifying and planning the ground water potential zones and watershed management (including the whole gamut of natural resources connected with the basin).

Hydrological investigation and behavior of watershed depend upon geo-morphometric characteristics of catchment. Morphometric analysis is commonly used for development of regional hydrological model of ungauged watershed. A critical valuation and assessment of geomorphometric constraints has been carried out. Prioritization of watersheds based on water plot capacity of Piperiya watershed has been evaluated by linear, aerial and relief aspects. Morphometric analysis has been attempted for prioritization for nine sub-watersheds of Piperiya watershed in Hasdeo river basin, which is a tributary of the Mahanadi. Sub-watersheds are delineated by ArcMap 9.3 software as per digital elevation model (DEM). Assessment of drainages and their relative parameters such as stream order, stream length, stream frequency, drainage density, texture ratio, form factor, circulatory ratio, elongation ratio, bifurcation ratio and compactness ratio has been calculated separately for each sub-watershed using the Remote Sensing (RS) and Geospatial techniques. Finally, the prioritized score on the basis of morphometric behavior of each sub-watershed is assigned and thereafter consolidated scores have been estimated to identify the most sensitive parameters. The analysis reveals that stream order varies from 1 to 5; however, the first-order stream covers maximum area of about 87.7 %. Total number of stream segment of all order is 1,264 in the watershed. The study emphasizes the prioritization of the sub-watersheds on the basis of morphometric analysis. The final score of entire nine sub-watersheds is assigned as per erosion threat. The sub-watershed with the least compound parameter value was assigned as highest priority. However, the sub-watersheds has been categorized into three classes as high (4.1-4.7), medium (4.8-5.3) and low ([5.4) priority on the basis of their maximum (6.0) and minimum (4.1) prioritized score.
