Calculation of Eco-Environmental Water Demand for River Dalinghe

Abstract:

According to the characteristics of north river, this paper used the minimum monthly average runoff method, the environmental function setter method and the annual average sediment concentration method to calculate the eco-environmental water requirement of mainstream of River Dalinghe. The results showed that: the non-consumptive water requirement was 4.46×10⁸m³ for Shangwobao Station, 8.87×10⁸m³ for Chaoyang Station, 13.96×10⁸m³ for Yixian Station and 7.26×10⁸m³ for Linghai Station per year; the evaporative water requirement was 0.019×10⁸m³, and the leakage water requirement was not taken into account in the consumptive water requirement. The eco-environmental water requirement of mainstream of River Dalinghe can not be satisfied basically, the management department should control the disposal of sewage strictly for it.
