【摘要】：运用马斯京根法进行河道洪水演算时,通常存在上断面及区间入流的预报误差及马斯京根法本身的误差。这些误差都会降低河道下断面洪水的预报精度。为此,基于系统反演理论,构建三种误差的反演方程并进行误差校正,以提高河道下断面洪水预报精度。淮河王家坝—润河集河段初步应用的实例表明,该方法可以提高马斯京根法的预报精度。
[Abstract]:When using Muskinggen method to calculate river flood, there is usually the error of upper section and interval inflow prediction and the error of Muskinggen method itself. These errors will reduce the accuracy of flood prediction under the channel. Therefore, based on the theory of systematic inversion, the inversion equations of three kinds of errors are constructed and the error correction is carried out to improve the accuracy of flood prediction under the river channel. The preliminary application of the Wangjiaba-Runhe reach of the Huaihe River shows that this method can improve the accuracy of the Maasjingen method.
