摘　　要：论述了日本城原川流域的防洪减灾措施及暴雨洪水特性,分析了在短历时集中降雨次数增加情况下,城原川流域短历时降雨对洪峰形成过程的影响,并利用改进的水箱模型对该流域年最大流量进行了模拟,指出对年最大流量贡献度较大的降雨历时为3～6 h,河道整治以48 h历时降雨为标准对河流流量进行推算的规划设计与实际情况背离。This paper discussed disaster - proof measures and storm flood character of Jobaru River Basin in Japan, analyzed the influence of short period rainfall to the peak formation process when the concentrated rainfall increases and used improved tank model to simulate the annual maximum flow of the basin. The 3 to 6 hours period rainfall pays greater contribution to the annual maximum flow, so using 48 hours period to calculate the river flow in fiver regulation is unreasonable.
