A Soil Erosion Model Based on Cellular Automata

It is of great significance to dynamically simulate and forecast the development and evolutionary of soil erosion process. Traditionally, most of soil erosion models are essentially steady-state models. Thus, they have limitations at real-time simulation on the initiation and development of soil erosion process. Cellular Automata (CA), with a “from down to up” dynamic modeling framework, is capable to simulate the spatial-temporal evolutionary process of complex geographical system. So, the basic idea about how CA will be applied to simulate soil erosion process is put forward. In this paper, the process model of soil erosion in one small watershed at loess hilly gully region of the Chinese Loess Plateau is constructed based on CA principles. This research also provides us a new methodology for the simulating and modeling soil erosion process. * Corresponding author. Yuan Lifeng, E-mail : [email protected]
