西南山区小流域供水保证率流量计算方法研究

Research on the Calculation Method of the Flow of Water Supply Guarantee Rate in Small Southwest Mountainous Areas

供水保证率流量计算是供水工程规划设计的重要内容,西南山区小流域径流观测资料缺乏,无法用实测径流资料推求。本文提出了三种计算方法,即实测调查法、参数等值线图法和水文比拟法。通过分析研究认为,西南山区小流域供水保证率流量计算以实测调查法为主,参数等值线图法和水文比拟法为辅助验证方法。

The flow calculation of water supply guarantee rate is an important content of water supply engineering ,because of the lack of runoff observation data in small southwest mountainous areas ,the method of measured runoff calculations is useless .This text presents three kinds of calculation methods ：the survey method ,the isoline map method and hydrologic analogy method .The survey method is the major method of flow calculation of water supply guarantee rates in small southwest mountainous areas through analysis ,the isoline map method and the hydrologic analogy method are used as auxiliary methods .
