Abstract:
The joint water supply regulation model of multi-reservoirs of the water diversion project from the Shuhe River Basin to Futuanhe River Basin was proposed according to the characteristics of the project. The model was based on two objectives including the maximum urban water supply and minimum surplus water. The model was solved using the Genetic Algorithm and the long-series time series method, and it was then used to determine the joint water supply of the Qingfengling, Xiaoshiyang, and Qiaoshan reservoirs in the Shuhe River Basin and Rizhao reservoir in the Futuanhe River Basin, which can provide the allowable limit reservoir storage of each reservoir in the Shuhe River Basin and dynamic water requirement limit of Rizhao reservoir in the Futuanhe River Basin. The results showed that the joint water supply regulation of multi-reservoirs can increase the water supply volume of 9.39 million cubic meters in the Shuhe River Basin compared with the water supply regulation of single reservoir, which suggested that the joint water supply regulation can improve the water supply potential of each reservoir in the Shuhe River Basin and therefore solve water shortage problem in the urban area of Rizhao.
