| Abstract | Water erosion often causes cultivated lands to degrade, particularly with regard to soil productivity. In addition to the reduction in arable lands lost, erosion has numerous offsite effects such as dam siltation. Erosion in the study area has been accelerated by climate regime, lithology, land-use change and topography. The study area concerns the Tlata catchment, located in northeastern Morocco. Satellite images were analysed for a 15-year period to determine the land cover and land-use changes, as well as the spatial patterns of erosion and deposition over this time period. Results of the land-use/land-cover change and meteorological data analyses indicate that the hydrological regime of the region has changed since the 1980s, following the beginning of the lasting drought, which is still ongoing over Morocco. For the Tlata River catchment, runoff coefficient increased and at the same time badlands extension also increased. This is correlated with land-use/land-cover change, which leads to the impermeabilization of the soil top layer, and the reduction of the water holding capacity. |
