摘要
"推理公式法"作为集总式雨洪模型常用于小流域暴雨洪水计算,暴雨递减指数作为敏感参数对计算成果影响较大。为提高模型计算精度,选用跃进水库入库水文站暴雨资料,分析率定新疆木垒县低山区暴雨递减指数。成果显示该区域暴雨递减指数随频率的增大而减小,随时段的增大而增大,以1h为界,n1在0.163―0.330之间,n2在0.597―0.764之间。分析成果可供周边设计暴雨计算及雨洪模型使用。
＂inferential formula method＂,as a lump-sum rainstorm flood model,is often used in the calculation of rainstorm flood in small watershed.In order to improve the accuracy of the model calculation,the rainstorm data of yuejin reservoir storage station was selected to determine the rainstorm decline index of low mountain area in mushi county of xinjiang at an analysis rate.The results show that the rainstorm decline index in this region decreases with the increase of frequency,and increases with the increase of the time interval.It is bounded by 1 h,n1 is between 0.163 and 0.330,and n2 is between 0.597 and 0.764.The analysis results can be used for peripheral design storm calculation and flood model.
