Optimal Operation of Floodwater Resources Utilization of Lakes in South-to-North Water Transfer Eastern Route Project

In order to meet the demand of emergency water supply in northern region without affecting normal transfer, considering use existing South-to-North Water Transfer eastern route project explore potential floodwater resource utilization flood season Hongze Lake and Luoma Jiangsu Province, this paper carried out relevant optimal operating research. First, hydraulic linkages between lakes were generalized, then resources allocation mode scale projects clarified. After that, actual available amount was evaluated. The average annual 2003–2017 1.49 billion m3, maximum capacity 30.84 m3. Then, using method multi period limited levels, research divided into main (15 July 15 August) later (16 August 10 September, 11 September 30 September) by Systematic Clustering Analysis method. control calculation, level can be raised from 12.5 m 13.0 m, reservoir storage increase 696 million 22.5 23.0 September), 23.5 (11 150 300 Finally, establishing optimization model lake group with goals maximizing transfer minimizing risk rate, scheme is obtained through algorithm.
