Etude de vulnérabilité a l'érosion hydrique du bassin versant du barrage de Boughrara (w. Tlemcen)

Abstract

Erosion is the result of external actions that cause soil degradation, all soils are naturally subject to erosion, resulting from the conjunction of many permanent factors likked to soil and topography ), which are variable or random such as precipitation and occur at different levels in erosion processes. The aim of the work is to produce a map of soil vulnerability to erosion by integrating fieldata, different thematic maps and satellite images through a GIS solution. This spatialization of the erosion hazard is implemented on the watershed of the Hammam Boughrara dam.
