Abstract
The experimental design developed to study the changes within storm in some surface (roughness and shear strength) and physical soil properties (bulk density, saturated hydraulic conductivity and porosity) is presented in this paper. The experience was carried out with a rainfall simulator on experimental plots (4m2) in an agricultural area located in South East of Spain. Two soils with different lithology were selected: Tertiary marls and Cuaternary colluvial deposits. The results indicated that the experimental design and rainfall simulator were successful to study the changes occurred in the soil during the rainfall and kinetic energy was found to be the best indicator of the changes produced during the storm, especially on marly soils.
