Study of soil erosion risks using RUSLE Model and remote sensing: case of the Bouregreg watershed (Morocco)

| Zusammenfassung: | The Bouregreg watershed is located to the north-western center of Morocco,
characterized by a semi-arid climate. It covers a total area of
approximately 10 000 km2. This basin is a very sensitive area to water
erosion. This causes the degradation of its vegetation cover and its land.
The most sensitive and poorly protected soils erode much more easily and
lose their fertility.The objective of this work is to quantify soil losses
by water erosion in the Bouregreg watershed using the Revised Universal Loss
Equation (RUSLE) and Geographic Information Systems. The average annual rate
of soil erosion in the Bouregreg watrershed are estimated at 20 t ha−1 yr−1. The
spatial distribution map of soil erosion show that 71 % of the total area
has low risk of soil erosion ( |
