Etude de l’érosivité des pluies sur le bassin de la Soummam par le biais de SIG et télédétection.

Abstract

The study of the rain regime and its erosive effects on the soil constitutes basic elements in all water reservation, soil, agricultural development and the hydraulic arrangement strategies. It is certain in this sense that the good knowledge of the erosive potential of rain is able to help the arrangers to fight erosion and to reduce reserve arrangements.In this context, we focus essentially on the rain aggressiveness as determinant factor of hydric erosion. As spatial context, we choose the drainage basin of SOUMMAM. The results shows that the west and the south of our basin are more vulnerable to the rain erosivity than the Est, concerning the north, is in security in front of the rain erosivity because of the density of his vegetal cover.
