A Study of Ecological Water Use Based on the Improved Tennant Method
To solve the existing problems arose in the Tennant method for estimating ecological water use in river course,a new methodology is proposed to replace the mean value by the median of runoff series in the Tennant formula.The motive is to eliminate the impact of some extreme values.Given runoff series of 47 years in Jiaokou reservoir of Zhangxi River,the traditional and the improved method were respectively applied to calculate the ecological water consumption in the river.The results show that the improved Tennant method is more reasonably than the traditional method.
