Joint Operation of Reservoir Group in Longxi River Basin Considering Agricultural Water Demand

Water resources in small- and medium-sized basins are often not reasonably allocated,and the utilization rate of water resources is not high.In this paper,five reservoirs in the Longxi River Basin are taken as an example.Firstly,the hydrological model is constructed,and the parameters of the model a...

description Water resources in small- and medium-sized basins are often not reasonably allocated,and the utilization rate of water resources is not high.In this paper,five reservoirs in the Longxi River Basin are taken as an example.Firstly,the hydrological model is constructed,and the parameters of the model are calibrated and verified by the 12-year measured runoff of Liujiantan Hydrological Station.The NSE can reach 0.89,the R<sup>2</sup> is 0.87,and the relative error (RE) is 5.4 %.The inflow process to the reservoir interval is obtained.Secondly,three representative crops of corn,rice,and sweet potato in the basin are selected to construct the reservoir irrigation water demand model.The crop coefficient method and Penman-Monteith formula are adopted to calculate the crop water demand and the USDA-SCS method was used to calculate the effective precipitation.Finally,the joint and single reservoir operation models of the Longxihe reservoir group to maximize the comprehensive water supply and power generation are built,and the POA solution and fuzzy analytic hierarchy process are utilized to optimize the scheme.The results show that the joint operation is more capable to balance the distribution of water resources between upstream and downstream reservoirs,improve the power generation efficiency and water supply guarantee rate,and reduce the amount of abandoned water than the single reservoir operation.
