山东省山丘区典型流域设计洪水成果分析

Design Flood Results Analysis of Typical Watershed in Hilly Region in Shandong

为验证山东省一般山丘区典型流域产汇流新参数研究成果合理性,文章采用设计暴雨计算洪水方法(含瞬时单位线法、推理公式法、地区经验公式法)分别推求了流域控制断面保证率为20%、10%、5%、2%、1%和0.5%的设计洪峰流量。基于新参数推求的设计洪水成果,文章采用流量资料推求洪水与查阅山东省水文图集方法对其进行了验证。

In order to verify the rationality of new parameters research result in runoff and concentration area in typical watershed in general hilly area, the paper derives the design flood peak discharge, based on the watershed control section assurance rate of 20%, 10%, 5%, 2%, 1% and 0.5% respectively, adopting the design storm flood method(including instantaneous unit line method, reasoning formula method and empirical formula method). With the basic of the design flood results derived from the new parameters, this paper verifies the results by means of calculating flood from the flow data and consulting the hydrographic atlas of Shandong Province.
