【摘要】:運(yùn)用馬斯京根法進(jìn)行河道洪水演算時(shí),通常存在上斷面及區(qū)間入流的預(yù)報(bào)誤差及馬斯京根法本身的誤差。這些誤差都會(huì)降低河道下斷面洪水的預(yù)報(bào)精度。為此,基于系統(tǒng)反演理論,構(gòu)建三種誤差的反演方程并進(jìn)行誤差校正,以提高河道下斷面洪水預(yù)報(bào)精度;春油跫覊巍獫(rùn)河集河段初步應(yīng)用的實(shí)例表明,該方法可以提高馬斯京根法的預(yù)報(bào)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.
