三水源新安江与相应涨差耦合模型的研究及应用

Study & Application on Coupling Models of SanShui Yuan XinAnJiang With Corresponding Rising Difference

本文从河道非恒定流St．Venant方程组出发，应用水文预报中洪水时段涨差的基本概念，建立了河道洪水预报的相应涨差模型，与区间洪水预报的三水源新安江模型相耦合，建立了三水源新安江与相应涨差耦合模型。经在资水拓溪～桃江区间洪水预报中应用，效果较好。

From the channel non-constant flow St. Venant equation group,this paper applies the ba-sic concept of flood time period rising difference in hydrologic forecast and establishes couplingmodels of SanShui Yuan XinAnJiang with corresponding rising difference. It has a better effectthrough the application in the flood forecast between ZiShuiTuo Stream^TaoJiang District.
