摘要

建立了水对土壤侵蚀的元胞自动机模型SCAVATU。与以前的模型相比，它涉及更多的状态，包括海拔、水深、总水头、植被密度、入渗、侵蚀、输沙和沉积。该模型应用于意大利南部卡拉布里亚的Fiumara Armaconi小集水区。第一次模拟给出了令人鼓舞的结果，即使需要现场侵蚀数据来验证和未来的校准和设置CA参数。该模型易于改进，可以作为经典的基于物理的方法的有效替代方案，通过简单的局部规则描述复杂性。

A Cellular Automata model for soil erosion by water

A Cellular Automata model for soil erosion by water, SCAVATU, was developed. It involves a larger number of states in comparison to the previous models, including altitude, water depth, total head, vegetation density, infiltration, erosion, sediment transport and deposition.

The model was applied to the small catchment of the Fiumara Armaconi, Calabria, Southern Italy. First simulations gave encouraging results, even if field erosion data is needed for validation and future calibration and setting of the CA parameters.

The model is susceptible to improvement and could represent a valid alternative to classic physically based methods, for the description of complexity through simple local rules.
