- Abstract
Aiming at the issue of eutrophication of artificial lakes in water-scarce cities, this study took the quantity, location and way of water diversion as the research elements and used MIKE21 software to perform numerical simulation of the water diversion effect on the south artificial lake in Ledu main city section of the Huangshui River Management Project in Haidong, Qinghai Province. It simulated 10 water diversion schemes and compared the water exchange rate of water body in the lake in order to identify the best water diversion scheme. The results show that the primary irrigating gate should be set in the location far away from the outlet. When the diversion flow is constant, the multi-diversion scheme with staggered water supply has better diversion effect than that of the single diversion scheme. The average water exchange rate and the minimum water exchange rate are both significantly improved. The water flow is better and the circulation degree is higher.
