摘要
防洪工程需要行洪淹没计算.本文把一维的洪水演算方法扩展成为二维,并直接应用曼宁公式,计算出水位与流量,效果与水力学方法相同.此法有简明易用,尺度大,机时省等优点,还可推广应用于湖泊水库水流,分流河段.水网汇流等问题.
The one-dimensional flood routing method is extened to two-dimensional, and the introduction of Manning's formula allows evaluation of stage as well as discharge. The method can also be applied to lakes, reservoirs, tributaries and water networks.
