Abstract EN

This study aimed to describe the water erosion modeling in Daher Aljabal and its surrounding areas in Al-Sowaida Governorate based on GIA and RS.

The water erosion risk map was obtained by applying GIS model developed on the basis of ten factors influencing the erosion process.

GIS layers were built for every factor.

The weights for all factors were added together.

Based on sum of these factors, water erosion was divided into six erosion risk levels.

Results showed that 12% of the study area was classified in levels 5 and 6, which reflect high and very high water erosion risks.

Land topography was the main factor in water soil erosion.

Terraces are effective ways to decrease the water soil erodability.

Results also showed that GIS and RS were powerful tools in water erosion risk assessment mapping.
