冲淤河道水位预报模型及其应用

A Model of Stage Forecast for Scouring and Silting Channel

摘要: 根据河流动力学基本方程,采用水文学与水-沙关系相结合的方法,建立了适用于不受回水顶托影响,以悬移质为主且水-沙关系良好的冲淤河道的水位预报模型,应用于渭河咸阳-华县河段,精度提高。

Abstract: Based on the river dynamics,a model of stage forecast for scouring and silting channel is developed by using hydrology method and the sediment rating curve.The model is usable for the channel without backwater effect and with the better sediment rating curve.A example is also given.
