Description :
This study presents a runoff feeding device, which is able to multiply the plot length virtually by supplying sediment loaded runoff from upstream. In the present study, this method is used to determine input parameters for the soil loss and deposition model EROSION 2D/3D under field conditions. Based on the model parameters “skinfactor, soil resistance to erosion and surface roughness” the experimental approach is described exemplarily. The experimental results show that results from large-scale rainfall simulations with the plot's length of 22 m can be reproduced successfully.
