Study on water resource allocation in reservoir irrigation areas considering the end of period storage benefits
摘要
Abstract
[Objective]The optimization and allocation of water resources was proven to be crucial in enhancing the overall efficiency of water utilization,aiming to maximize and optimize the overall benefits of water resource utilization.[Methods]Facing the challenge of formulating water allocation plans for reservoirs with irrigation tasks in irrigation districts,a water resources optimization and allocation model was proposed,targeting maximized comprehensive benefits during the reservoir operation period,maximized storage benefits at the end of the period,and minimized water discards.A benefit function for end-of-period storage was constructed,and the multi-objective problem was transformed into a single-objective model,which was then solved using the genetic algorithm.Taking the Zhanghe Reservoir Irrigation District in Hubei Province as a past example,the model was utilized,based on a water demand forecasting model,to analyze domestic,industrial,and irrigation water demands.Considering the uncertainty of inflow at the end of the reservoir operation period,a relationship for end-of-period storage benefits was established.The model then facilitated the optimal allocation of water resources.[Results]The result revealed that the proposed method had yielded higher overall benefits.Based on water demand predictions for the year 2024 and under different rainfall frequencies(P=25％,50％,75％),compared to the reservoir operation chart method that had been used,the comprehensive benefits of the reservoir were increased by 610,000 yuan,300,000 yuan,and 130,000 yuan,respectively,under different rainfall frequencies of P=25％,50％,and 75％.Meanwhile,the end-of-period water levels were lowered by 1.9 m,0.85 m,and raised by 0.25 m,respectively.[Conclusion]The quantification of end-of-period storage benefits,which represent the risk of comprehensive benefits arising from uncertainty in future inflows after the operation period,played a significant role in water resources optimization.This approach enabled the optimal allocation of water resources during the reservoir operation period to achieve maximum economic benefits in the reservoir-irrigation district system.It also guided the setting of end-of-period water levels,thereby enhancing the overall efficiency of water utilization from the water source perspective.关键词
