Water flow simulation and emergent treatment procedure of water supply channel without control gate

摘要

It is difficult for reservoirs to guarantee their main water supply aims when the water demands are tremendous and the control gats in its water supply channel are inavailable. In this papper three monitor points are set in the start, the middle and the end of the channel of the Jinxiuchuan reservoir. The collected monitoring data are input into Mike 11 to simulate the procedure of water flow procedure in this channel during the irrigation period when the rural water demand and municipal water demand are conflict. The relationship of water amount achieved by the municipal users and the water levels along the channel are analyzed; the threshold values of water supply risk are obtained, so that the emergent treatment program is made, which can provide technology support for reservoir's water supply decision.
