清漳河流域刘家庄水文站设计年径流量及年内分配计算

Calculation of Annual Runoff and Annual Distribution of Liujiazhuang Hydrological Station in Qingzhanghe River Basin

年径流分析计算是水资源利用工程中最重要的工作之一,设计年径流是衡量工程规模和确定水资源利用程度的重要指标。通过分析邯郸市涉县刘家庄水文站1960~1992年实测径流资料,对实测径流量进行可靠性、一致性和代表性审查,并对还原后的天然径流资料进行频率分析计算,确定其统计参数,得出刘家庄水文站丰、平、枯水年不同保证率下设计年径流量及其年内分配过程,为涉县清漳河流域水资源论证和水资源开发利用提供依据。

Analysis and calculation of annual runoff is one of the most important tasks in water re- sources utilization, The annual runoff is an important index to measure the scale of the project and determine the degree of water resources utilization. Based on the analysis of the liujiazhuang hydro- logical station＇ s measured runoff data from the 1960 to 1992 in Shexian County, Handan. The measured runoff was reviewed, and the natural runoff data were calculated and analyzed and statisti- cal parameters was determined. It is concluded that the annual runoff and its annual distribution in different hydrological conditions of the liujiazhuang hydrological station, the research aimed to pro- vide basis for water resources demonstration and water resources development and utilization in Zhanghe River Basin of Shexian County.
