Abstract

This work aims to assess the impact of the vegetation cover on water erosion in Kharouba watershed in Morocco Central Plateau. The methodology is based on diachronic analysis of land cover between 1986 and 2008, using 1986 aerial photographs and a 2.5 m resolution SPOT satellite image from 2008. The land cover maps obtained were used to develop erosion status maps for 1986 and 2008, using PAP/RAC methodology. The results achieved highlight the regressive evolution of vegetation cover between 1986 and 2008. This decline contributed to the increase of water erosion risk in Kharouba watershed, which causes the expansion of vulnerable areas to water erosion from 39% of the basin surface in 1986 to 45% in 2008.
