漳泽水库汛限水位计算

Calcutating the Flood Control Level for the Zhangze Reservoir

运用模糊水文学理论计算水库汛限水位,可把汛期作为全年的一个模糊子集,通过计算漳泽水库汛期每日的经验隶属度和理论隶属度,选取两者大值作为综合隶属度,然后由综合隶属度与防洪库容函数关系计算出每日水库库容,查水位库容曲线表,进而计算出每日汛限水位。

Using the fuzzy hydrology theory to calculate the flood control level of a reservoir,and taking the flood season as a fuzzy subset of the whole year,the paper calculates the daily experimental and theoretical membership grades of the flood season of the Zhangze Reservoir,selects the bigger value between the daily experimental and theoretical value as the comprehesive value and then calculates the daily reservoir capacity by using the function relationship between the comprehensive membership grade and the flood controled capacity,through seeking the stage capacity curve,further calculates the daily flood control level in flood season.
