以景泰县驼水沟流域为研究区，利用景泰气象站1958-2013年最大24 h降水资料推求典型暴雨并建立暴雨强度-历时关系曲线。以驼水沟流域土地利用类型面积为权重计算流域平均径流系数，采用诺模图法求解流域汇流时间，并推求不同频率下沟谷漫滩区暴雨洪水特征参量，为干旱沟谷漫滩资料稀缺地区暴雨洪水计算提供方法借鉴。

The Tuoshui Basin of Jingtai County was selected as the study area. The observations by the gauge station there of rainstorms for a maximum 24 hours from 1958 to 2013 were employed to estimate the relationship between rainstorm intensity and its duration. The land use types were used as the weights for the calculation of the basin-averaged runoff coefficient. The basin concentration time was defined by a nomograph. Based on the above analysis, the characteristic values of rainstorm and flood under different reoccurrences were determined. The study can serve as an example for rainstorm and flood calculation in the arid valley-overbank area.
