Gully erosion of the Mount Dirbishk area in Akre district (geomorphological investigation)

The intensity of gully erosion varies in the study area located in Akre district, depending on several factors, the most important of which are rock formations, as the resistance of rocks to erosion varies, which affects the intensity of gully erosion. The difference in slope directions also affects the speed of water flow, which affects the quality of the drainage network and its branches, not to mention The amount of rain affects the intensity of gully erosion. The density of vegetation cover protects the soil from erosion. All of these factors help to increase or decrease the degrees of gully erosion. The intensity of erosion was calculated using the Bergsma equation based on the Landsat satellite data taken on 7/8/ 2023 using the GIS 10.8 ARC program. They were classified according to their degrees of intensity, lengths, and percentages, which showed that the erosion system is considered one of the high erosion systems and is prevalent in the study area, as it constitutes (45.90%) of the total area of the region.
