  • Rainfall simulation experiments are widely used in geomorphological research in badland areas. This technique contributed significantly to our understanding of badland geomorphology in the Mediterranean belt. This study confirmed that rainfall
  • simulations are well suited to 1) analyse runoff-infiltration processes and sediment detachment within badlands, and 2) to establish the factors determining the hydrological and erosion response at interrill scale in badland areas. Rainfall simulations
  • increase our understanding of the temporal and spatial variability of the soil erosion processes. However, rainfall simulation provides mostly qualitative rather than quantitative information. Moreover, this method allows the comparison amongst different
  • environments and soil conditions as the rainfall properties can be reproduced.

  • favor piping, gullying and rilling during the rainfall maxima. Soil erodibility in this area is clearly controlled by the sodium content and the presence of swelling clays. These factors determine the distribution and appearance of piping processes
  • or semi-arid areas. Mudstone is deteriorated and saline materials are concentrated near slope surfaces. It is highlighted that the deteriorated surface layers are removed by rainfall in rainy seasons.
