تقدير حجم التربة المغسولة بفعل التعرية المائية وآثارها البيئية في حوض وادي كالي مرمك - قضاء رانية باستخدام التقنيات الجغرافية الحديثة
Abstract
This study aims to evaluate the phenomenon of soil erosion by water erosion through the use of the EPM model. This model is an experimental and semi-quantitative method that can estimate the amount of sedimentary revenue as well as determine the severity of water erosion and indicate the areas that are likely to be threatened by erosion. The model has several indicators, including the regression index, the soil protection index, the vegetation index, the precipitation indicator, and the heat index, and through the Geographic Information Systems program, these indicators can be combined to calculate this model, estimate the potential erosion coefficient, the size of the eroded soil and its qualitative and quantitative for its environmental effects, the study showed that (67%) From the study area lies within grades 5 and 6 that reflect a high and very high susceptibility to erosion, the results also showed that the topographic factor that includes the degree of slope and the shape of the slope and the Earth system and the shape of the Earth contribute effectively to the occurrence of water erosion, and that the terraces are an effective way to reduce the risk of drifting in the studied area, as the study demonstrated that software geographic information systems and data sensing technology are effective tools in soil mapping And the problems related to it, especially the problem of water erosion and its environmental effects.
