Erosion processes on different relief units: the relationship of form and process

摘要: Geomorphological relief units are related to certain processes and the history of their development. They well defined by form material. This study investigates erosion on different units. Rainfall simulations, rill experiments monitoring aerial photography were performed dunes, glacis, Holocene fillings, talus material Quaternary loam terraces in order analyse varying process intensities. Splash, interrill runoff generation quantified rainfall simulation experiments, gully growth over several years. The test sites situated NE- SE-Spain, S-Morocco N-Burkina Faso. results clearly show that measured very from those supposed be relevant for formation Dunes fillings highly erodible splash erosion. In contrast, a low susceptibility processes. We conclude dominances differentiation is more significant with increasing scale complexity process: extent varies much between than do.
