تقدير حجم انجراف التربة في حوض وادي الطيب باستخدام EPM

Abstract

     The study focused on predicting soil erosion and studying its spatial distribution in the Tayeb Basin using the Erosion Model (EPM) also known as Gavrilovic, integrated into the GIS (Geographic Information System) program. The spatial distribution of soil erosion shows five main zones in the studied area (very slight, light to moderate and severe, very severe).

The main factor in the EPM (erodibility of moisture, degree of moisture and slope, temperature and rainfall length) was evaluated using the GIS program. The data layers used in this study were generated from the Digital Elevation Model (DEM), and the Landsat 8 satellite digital number, and the highest amount of erosion occurred in the northern areas, and the highest values of erosion were reached in Tayeb and .((140000-56000
