一维水动力学模型在淮河干流的应用
首发时间:2008-08-21
摘要:本文根据天然河道的水动力学特性,建立了一维水动力学模型(即圣维南方程组)。采用vb编程编制了一维水动力学模型,并对淮河干流蚌埠到花园咀的水流进行模拟,对一维河道糙率进行拟合率定尽量减少水位,流量的计算值和实测值之间的误差,经验证模拟值与实测值的误差在一定的范围之内

One-dimensional Hydrodynamic Modal used in
Abstract:n the basis of hydrodynamics characteristic of natural rivers ,1-D hydrodynamic model (saint wenant equation) is established In this paper .VB is used to develop the general hydrodynamic modal.in order to solve the problem of choice parameter on modal ,one dimension river flow roughness parameter is revised to reduce the error between metrical value and calculative value . After validating the relative difference between simulation value and field measured value can be controlled in a definite scope .
Keywords: One-dimensional Hydrodynamic Modal,main stream of huaihe river,roughness parameter revise
