Morphometric Analysis of Galal Bedrah River Basin Using STRM (DEM) Data and GIS Techniques
A morphometric analysis of Galal Bedrah river basin was carried out by several processes that take place on STRM DEM (Shuttle Rader Topography mission), thereby employing the Spatial Analysis tool in Arc GIS (version 10.5) software for analyzing the study area. Primarily, the Arc GIS software was the basic tool used for extracting the river Basin as well as its drainage network. Upon analyzing, the drainage network was classified using Strahler’s System for classification, which in turn reveals that the drainage pattern is almost dendritic, with the basin order being fifth-order. The study further evaluates the morphometric parameter and its influence on soil physical, landform, and other hydrologic characteristics. The mean bifurcation ratio (Rbm) was found to be 2.35 that have a strong effect on the runoff and its intensity, high relief value, drainage density, and stream frequency. All these values indicate that the basin exhibits erosion and sediment transfer and play a significant role in different hydrological studies.
