摘要
本文应用变量变换法使洪水流量的偏态分布趋向正态,并根据正态分布的参数推算给定功率的洪水变换值,最后转化为设计洪水。文中利用福建省九龙江流域、晋江流域的实测水文资料,对变换法和现行P-Ⅲ型适线法进行比较,结果表明,变换法是可行的。
This paper presents a method of variable transformation for estimating the flood flow. By applying this method, the skew distribution of flood flow turns towards normal. Thereby the transformed values of flood in given frequency can be calculated according to the normal distributed parameters and converted into design-flood. The application of this method is compared with that of the exist- ing Pearson type Ⅲ curve fitting method on the measured hydrological data ga- thering from Jiu Long Jiang river valley and Jin Jiang river vally. The compari- son confirms the feasibility of this method.
