| 摘 要： | 具有物理基础的分布式水文模型,是目前国内外水文学者颇感兴趣的科研课题.本文从物理概念出发,对流域产汇流和产输沙过程均采用分布式模型,并将二者有机结合,建立质量和动量的守恒方程.模型中应用了GIS技术,计算结果与监测值比较符合.本文模型可用来进行小流域的径流量及产沙量的预报计算.

| Abstract: | In recent years,physically based distributed hydrological model is an interesting subject for hydrological researchers at home and abroad.Based on the physical mechanisms,distributed runoff model and sediment model are integrated organically by equations of mass conservation and momentum.The technique of GIS(Geographic Information System)is also used in the simulation.The calculated results coincide with the monitored data.This model can be developed for predicting the amount of runoff and sediment yield in small watershed. |
