| Abstract : | Abstract. In semi-arid Mediterranean regions the pressure on natural resources such as water and soil is in-creasing. In the Maghreb, soil degradation and reservoir sedimentation are serious problems, particularly in catchment areas with a high proportion of marls. As part of an Algerian-German project of scientific-technical cooperation, the runoff from soils on marls was studied, using modern rain simulators. A description of the rainfall experiments is followed by the presentation of a simple and appropriate mathematical approach to the modelling of runoff from soils on marls, and by a discussion of the influence of cultivation on water infiltration and runoff of these soils. |
