Abstract
Geomorphological processes inside a river basin have an impact on water supply and scarcity. Identifying the effect of geomorphological processes on basin hydrology, necessitates a quantitative evaluation of river basin morphology. The Maner River basin’s nine sub-watersheds (SWs) were chosen for this present chapter study. The Shuttle radar topography mission (SRTM) digital elevation model (DEM) was utilized for hypsometric analysis. The catchment’s volume of rock mass and the quantity of erosion occurring there in relation to the remaining mass are both expressed by the catchment’s hypsometric curve. The area under a hypsometric curve was utilized to determine the hypsometric integral (HI). In a geographical information system (GIS) context, the HI value was calculated using the elevation-relief ratio method. These variables were statistically examined by classifying them into distinct groups using the natural break interval method. The erosion process is divided into three stages: the old period, when the catchment is completely stabilized; the equilibrium or mature period; and the in-equilibrium or early period, when the catchment is extremely susceptible to erosion of soil. The HI values for all of Maner’s sub-catchments range between 0.39 and 0.64. As a result, higher priority has been assigned to SW3 and SW5, medium priority to SW1, SW2, SW4, and SW6, and lower ranking to SW7, SW8, and SW9. The high priority represents the sub-catchments that are most susceptible to soil erosion. These findings will aid in the development of proper water and soil conservation measures to decrease soil erosion throughout the catchment.
