Abstract: The objective of this present work is to produce a synthetic distribution map of
sensitivity degrees to erosion on the level of the high and middle Cheliff basin, by
using the superposition model of cards “model builder” on ArcMapTM. The latter is
exposed to a serious problem of soil degradation causes siltation of the majority of the
dams distributed on his whole. Indeed, four classes of erosion vulnerability have been
distinguished (weak, average, strong and very strong) where the strongly vulnerable
areas cover the most part of the basin. The map produced provides an excellent decisionmaking
tool for managers, in order to better target their preventive intervention
strategies.
