Study on staged drought-limited water levels for Three Gorges Reservoir
摘要
Abstract
With the development of society and economy under global warming,extreme drought events occur frequently in the Yangtze River Basin(YRB),and the Three Gorges reservoir is faced with a severe challenge in guaranteeing water security in the middle and lower reaches of the Yangtze.Drought-limited water level(DLWL)is a crucial parameter for reservoir drought relief operation to enhance this basin's drought mitigation capability.This paper defines the reservoir's staged grading DLWL,and construct a multi-objective optimization DLWL model based on a parameterization-simulation-optimization framework that is solved by an intelligent optimization algorithm.The results show that the reservoir's DLWL is more significant in flood season than non-flood seasons,and DLWL at the first grade is 154 m,156.9 m,and 164.8 m in the stages of 6/10-7/31,8/1-9/9,and 9/10-30 respectively.By implementing DLWL operation,the reservoir can improve all the benefits-in terms of impoundment,power generation,water supply,and navigation-each to a different degree.The increases in power generation will be 1.29%and 6.54%for multi-year average and typical dry year,respectively.This study would be useful for reservoir DLWL operation and drought-relief operation.关键词
