水文分析是平原区小水库常规的一种使用方法。按20年一遇洪水设计,100年一遇洪水校核对李林水库进行设计洪水复核计算。由于李林水库流域内无实测流量和雨量资料,因此,设计洪水采用与王大塘水库及李林水库相距不远的王勿桥水文站资料。根据王勿桥水库的设计洪水成果根据面积比推算出李林水库的设计洪水成果。李林水库设计洪水过程线采用典型洪水过程线放大法。由于李林水库地形、地貌及下垫面因素与临近的已批临的小岗水库相似,故对水库设计洪水成果与小岗水库的设计洪水成果进行对比,设计认为李林水库的设计洪水成果是合理的。
Hydrological analysis is a routine use of small reservoirs in the plain area. According to 20 years of flooding design, 100 cases of flooding check LiLin reservoir design flood review calculation. Due to the unmeasured flow and rainfall data in LiLin reservoir, the data of WangZuQiao Hydrological Station which is not far from WangTang reservoir and LiLin reservoir is used as design flood. Based on the design flood results of Wangxuqiao Reservoir, the design flood results of LiLin Reservoir are calculated based on the area ratio. Li Lin reservoir design flood process line using a typical flood process line amplification method. Due to the similar topography, geomorphology and underlying surface factors of LiLin Reservoir and the adjacent approved Xiaogang Reservoir, the results of the design flood of the reservoir are compared with those of the Xiaogang Reservoir. The design flood results of the LiLin Reservoir Is reasonable.
