摘要
山区小流域往往实测水文资料不足或无实测水文资料,因此对于山区小流域设计暴雨的推求通常采用间接方法。现以灵石县曹村沟小流域为例,在外业调查成果的基础上,综合分析小流域设计暴雨计算方法,选用适当方法推求不同频率的设计暴雨,计算内容主要包括设计点暴雨、设计面暴雨、设计暴雨的时雨型和设计暴雨的时程分配等。推求的设计暴雨成果为山区小流域设计洪水的推求提供数据参考,并为山区山洪灾害预警预案编制提供数据支撑。
Mountain watershed hydrological data often insufficient or no hydrologic data, so to get the design rainstorm usually adopts the indirect method. This paper is based on the case study of Ca- ocun Gully watershed in Lingshicounty, based on the results of field investigation. The calculation method of the comprehensive analysis of small watershed design storm, choose the appropriate meth- od to deduce the different frequency of design storm, the main contents include ： design of rainstorm, the type of design rainstormand the temporal distribution ofdesign rainstorm. The results for design storm provides reference data for the calculation of design flood of small watershed in mountainous area and also provides data support for the mountain flood warning plan.
