runoff erosion

The process that runoff and sediment material collect into the channel and migrate through the channel network is important in simulating the hydrological and erosion areas. And river confluence relations in the basin is the base of hydrological and erosion models.

径流和泥沙物质向沟道的汇集和通过沟道网络系统的运移过程，是水文和侵蚀模拟的重要环节，而流域之间汇流关系的建立，则是流域水文和侵蚀模型的基础。
