التعرية الأخدودية في حوض وادي هزان

Abstract

The gully erosion is the most important geomorphological features that characterize the Hazan valley, which are not varied due to the nature of the geological formation, which is resistant to erosion. The water drainage map was used for the study area to determine the effect of erosion on the surface of the study area Type DEM (Digital Framing Model) and manipulate it using Arc Map 10.3 software. There were five degrees of erosion and the region dominated the average erosion according to Bergsma equation.
