- Abstract:
-
Rill erosion is an important link on the transition from sheet erosion to gully erosion,and is an important component of water erosion physical process on hillslope.Rill erosion research is of great importance to comprehend erosion and sediment mechanism on slope surface.Traditional erosion model is difficult to accurately dynamic simulate and reproduce rill initiation and development process on slope,and this process is self-organizing.Cellular automata,simple named ‘CA’,is a ‘from down to up’ dynamic modeling framework.It is able to simulate the spatial-temporal evolutionary processes of complex geographical system.By interaction between one cell and another,CA can show a great deal of complex non-linear action and phenomena as a whole.CA-Rill,a rill erosion dynamic model on loess slope,is constructed by use of theory and method of cellular automata.The dynamical virtual experiment is carried out for rill self-organizing process on slope.A rill initiation and development process is simulated vividly.The experimental results are analyzed.This research is a breakthrough in traditional test approach,and gives us a new way for researches in rill erosion.
