Description :
By means of simulated rainfall the influence of the slope angle on the soil, water and seed erosion has been studied on badland surfaces. Slope angle has a clear influence on runoff initiation, with cracks and crusts as the main factors controlling the time to ponding and time to runoff. Steady-state infiltration rates and seed losses have an inverse relationships with slope angle. The different behaviour of seed losses between pediment and slope is due to the strategy of the seeds against erosion processes.
