我们已经开发了一个模型，其中包括从降雨和土壤崩塌的陡坡侵蚀的影响，模拟河流网络的形成和演变。雪崩提供了一个机制，在相邻的河流流域之间的增长竞争。变化的形态遵循格洛克提出的许多进化特征。我们发现，在演化过程中，该模型保持了在自然河流系统中测量的统计特性。
We have developed a model, which includes the effects of erosion both from precipitation and from avalanching of soil on steep slopes, to simulate the formation and evolution of river networks. The avalanches provide a mechanism for competition in growth between neighboring river basins. The changing morphology follows many of the characteristics of evolution set forth by Glock. We find that during evolution the model maintains the statistical characteristics measured in natural river systems.
