| Zusammenfassung |
| Overland flow generation on a hillslope can be seen as a two-dimensional (2-D) process. In
many studies the hillslope is represented as a plane surface with a certain longitudinal slope,
and 1D models (e.g. kinematic wave theory) are used to simulate the overland flow
generation process. However, most hillslopes also have a transversal slope and, in order to
correctly represent overland flow and the associated transport process, a 2-D model for
overland flow needs to be developed. Laboratory experiments can be a useful tool to test the
performance of such a model.
The work described here aimed to provide experimental data so that a model able to
simulate 2-D overland flow could be built. The goal of this experimental study
was to assess the rill and inter-rill two dimensional overland flows and sediment
loss.
Three experiments were carried out at the Laborat |
