تحليل جغرافي لحجم التعرية الأخدودية لأحواض شمال شرق كلار باستخدام GIS و RS

Abstract EN

Gully erosion is one of the geomorphological processes the study area is characterized by, which appears to varying degrees due to the nature of geological formations.

Finding them out was based on digital elevation model (Dem) using the Arc (Map GIS 10.4) program.

The study showed the existence of (5 degrees) of erosion, which are; no-erosion domain which occupies (35) sites with an area of (70.83) km2 (4.5% ), very light erosion domain occupying (64) locations with an area of (336.39) km2 (21.8% ), the domain of light erosion which occupies (19) sites with an area (367.98) km2 (24.7% ), medium erosion domain in (80) locations with an area of (545) km2 by (35.3% ), and finally high erosion domain, occupying (27) locations with an area of (212) km2 (13.7% ).

Thus, the light erosion domain is the highest among them all.
