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...
Morphometric Analysis and Prioritization of Sub Watersheds of Umar Nala Watershed
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.
Prioritization of watershed is an important step in conserving and managing water resource. Morphometry is the measurement and mathematical analysis of configuration of the earth's surface, shape and dimensions of its landforms. Drainage characteristics are important analysis to study the prevailing Lithology, Soil, Geomorphology and Slope of an area. An attempt had been made to prioritize the subwatersheds into Groundwater prospect zones as very good, good, moderate, poor and very poor groundwater prospect zones. Drainage networks are extracted from Cartosat DEM data. Watershed is delineated using hydrological tools in ArcGIS 10.1. Based on third order contact subwatersheds are classified to analyze the micro level planning and management. 10 linear parameters such as Stream order, Stream length, Bifurcation ratio, Drainage density, Dranage texture, Stream frequency, Elongation ratio, Form factor and Constant of channel maintenance were calculated by morphometric analysis using ArcGIS 10.1. Weightage were assigned based on the infiltration and holding capacity of groundwater. Groundwater potential prioritization map has been prepared by assigning each subwatershed weightage. The results can be used to allocate proper budget to watershed planning and in recharge structure prioritization. Hence management and proper utilization can be carried out to sustain the Groundwater resource.
The study area is one of the sub-river basin of Krishna river, covering an area of 3035 km² and lies in west part of Maharashtra state bounded by Latitude 16 0 55' to 17 0 28' N and Longitude 74 0 20' to 74 0 40' E. Poor soil cover, sparse vegetation, erratic rainfall and lack of soil moisture characterize the study area for most part of the year. Due to unavailability/poor managed of surface water storage structures, more than 50% area depends upon groundwater for their daily needs. Recurring drought coupled with increase in ground water exploitation results in decline in the ground water level. So the entire study area has been further divided into 9 sub-watersheds named SWS1 to SWS9, ranging in geographical area from 76 km² to 492 km² and has been taken up for prioritization based on morphometric analysis using Geographical information system (GIS) and remote sensing techniques. The drainage density of sub-watersheds varies between 2.07 to 3.26 km/km² and low drainage density values of sub-watershed SWS5 indicates that it has highly resistant, impermeable subsoil material with dense vegetative cover and low relief. The elongation ratio varies from 0.2 to 0.35 which indicates low relief and gentle ground slope. The high value of circularity ratio for SWS 8 sub-watershed 0.6 indicates the late maturity stage of topography. This anomaly is due to diversity of slope, relief and structural conditions prevailing in this sub-watershed. The compound parameter values are calculated and the sub-watershed with the lowest compound parameter is given the highest priority. The sub-watershed SWS3 has a minimum compound parameter value of 1.68 and SWS 8 has a maximum compound parameter 3.08. Hence it should be provided with immediate soil conservation measures because sedimentation is the major problem for surface water storage structures.

Watershed management is an important in today's environment. Prioritization of subwatershed plays an important role in watershed management studies. It shows the requirement of watershed study to go for the green growth of the region. Physical and social factors are also play an important role in identifying the sub-watershed for Prioritization. The present research is throwing a focus on how morphometric parameters in association with GIS analysis will help in identifying the ranking of sub-watersheds for further development with the help of suggested watershed structures. Shevgaon and Pathardi tahsils are known for drought prone tahsils of Ahmednagar district in Maharashtra. These tahsils comes under the semi-arid region. Subwatershed prioritization is necessary for proper planning and management of natural resources for sustainable development of the study area. Scarcity of rainfall and increasing population pressure on the land as well as water resources. Hence, researcher has selected Shevgaon and Pathardi tahsils for sub-watershed prioritization. There are seven sub-watersheds selected from two tahsils for present research work. Morphometric analysis of all these sub-watersheds is taken into consideration for this research. The largest sub-watershed is Erdha sub-watershed which is located in Karanji circle of Pathardi tahsil, having an area of 145.06 km 2 and smallest subwatershed is Erandgaon sub-watershed in Shevgaon tahsil, having an area of 40.143 Km 2. The drainage density of sub-watersheds varies between 1.83 to 2.80 p/km 2 it indicates coarser drainage structure. Lowest drainage density value is found in Chapadgaon sub-watershed which is 1.83 p/km 2 and highest drainage density value is found in Chandani watershed which is 2.80 p/km 2. The elongation ratio varies from 0.32 to 0.70. It indicates that all sub-watersheds have elongated shape. The high value of circularity ratio of Erandgaon watershed which is 0.64. The compound parameter values are calculated for selected sub-watersheds. Lowest compound parameter value is given the highest priority and highest compound parameter value is given the lowest priority. In this research Erandgaon sub-watershed has a lowest compound parameter value which is 2.99 and Chandani sub-watershed has a highest compound parameter value which is 5.38. Prioritization is done on three levels depending on the result such as high, moderate and low priority groups.
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...
The Upper Tons River Basin of North India has been selected for prioritisation of sub-watersheds (SW) based on morphometric parameters with respect to groundwater derived from topographic sheets and CARTOSAT data. There are 10 SW have been delineated in the region, high stream frequency (F s ) values of SW (1-5) and SW-9 indicated the occurrence of steep slopes, less permeable rocks, greater runoff, less infiltration possibility. Further, these regions have been predicted as poor groundwater potentialities. SW-2 has been identified as poorest groundwater potential zone, whereas SW-4 and SW (6-8) regions possess good permeable bed rocks. The Drainage density (D d ) map demonstrated that the middle south-west region possesses higher D d whereas northeastern regions contain lower D d . Further, the areal parameters indicate elongated shape of the basin, hilly region has moderate to steeper ground slope. The outcomes of work have potential to manage groundwater and to ameliorate the flash flood and droughts.

In this study, morphometric analysis and prioritization of 12 sub-watersheds of Brahmani and Baitarni Basins, which are located in Keonjhar and Sundargarh Districts of Odisha State, India is carried out using Remote Sensing and GIS techniques. The morphometric parameters considered for analysis are stream order, stream length, bifurcation ratio, drainage density, stream frequency, texture ratio, form factor, circulatory ratio, elongation ratio, relief ratio, length of overland flow and basin shape. A total number of 1654 streams were identified of which 1223 are first order streams, 320 are 2 nd order, 77 are 3 rd order, 20 are 4 th order, 6 are 5 th order, 4 are 6 th order and 4 are of 7 th order. The streams up to seventh order can be seen in BAISWD6, BAISWD7, BAISWD8, and BAISWD11. Drainage patterns of stream network from the basin have been observed as mainly dendritic type which indicates the homogeneity in texture and lack of structural control.The drainage pattern is dendritic and the highest order stream is of 7 th order. The bifurcation ratio (Rbm) varies from 2.99 to 5.91 and all sub-watersheds fall under normal basin category. The drainage density (Dd) of the study area is varying between 2.05 and 2.89 km/km 2 indicating low density with highly permeable subsoil, thick vegetation cover, low relief and course drainage texture. Elongation ratio of all the watersheds varies between 0.65 to 0.70 respectively and indicating that it is elongated. Circulatory Ratio (Rc) ranges from 0.38 to 0.68 indicating that all the sub-watersheds except BAISWD6 are more or less circular and are characterized by high to moderate relief and drainage system is structurally controlled. The sub-watershed BAISWD6 having the Rc value of 0.38 indicating that it is elongated. The relief ratio of all sub-watersheds varies between the values of 23.56 to 47.59m, which indicates that the basin has strong relief and steep slope. The compound parameter values of 12 sub-watersheds of study area were calculated and prioritization rating was carried out. Sub-watershed BAISWD9 with a compound parameter value of 5.6 receives the highest priority indicates the greater degree of erosion in the particular sub-watershed and it becomes potential area for applying soil conservative measure.
