Design storm hyetograph is the essential element for hydrologic modeling analysis and storm water drainage design. 摘要设计暴雨雨型对水文模式分析与暴雨排水设计是不可或缺的基本要素。
A storm hyetograph constructed by annual maximum rainfall series can distribute the design rainfall depth for specific duration and return period. 在水工设计上，针对年最大降雨序列演算的暴雨雨型，可将频率分析所求得的降雨深度做时间上的分配，以便进行各种水文分析。
Based on error analyses, the modified ranking method showed a good result for solving the design hyetograph of different durations. 经误差分析证实福山地区设计雨型历线推求，以修正位序法较佳，因而采用修正位序法建立不同降雨延时之设计雨型历线。
