Digital modeling of the geomorphological characteristics of the Wadi Lamsa Basin

Abstract

The study intended to produce an integrated digital model of the Wadi LHMSAH basin, incorporating maps of elevations, slopes, and drainage networks and providing accurate morphometric data. This was achieved using Geographic Information Systems (GIS) software and Digital Elevation Models (DEM). A descriptive-analytic approach was employed to describe the drainage basin and its stream network and analyze the results of the morphometric measurements. Furthermore, these measurements were calculated using a quantitative method engaging several parameters to determine the dimensions and morphometric characteristics of the basin. This study revealed various findings, including the elongated shape of the Wadi LHMSAH basin, probably due to the homogeneity of the geological formations in it. Moreover, the Relief Ratio and Ruggedness Value indicated a low roughness of the basin's surface. Meanwhile, the basin's Hypsometric Integral suggests a mature phase in its erosional cycle.
