Optimal Living Water Scheme of Polder Area Along the Changjiang River Considering Water Quality and Hydrodynamic Conditions

In order to explore the optimal living water solution for the polder along the Changjiang River in consideration of water quality and hydrodynamic conditions,taking the Tuanjie polder in Nanjing as an example,a one-dimensional river network hydrodynamic and water quality coupling model was constructed using MIKE to reasonably determine the hydrodynamic and water quality improvement goals.On the basis of the changes in water supply source,water quantity,live water point,time to reach the standard,and changes in the live water scheduling mode,the live water plan was designed,and the simulation results of each plan were analyzed to select the optimal live water plan.The results show that the optimal diversion scale for diversion of water from the Changjiang River and Gaowang River is 25m3/s for each pumping station on the east side and 10m3/s for each pump station on the south side.The optimal drainage scale is for the north and west sides.At the same time,the drainage scales are 15m3/s and 20m3/s respectively,and the optimal scheduling method is drainage simultaneously.The research results can provide a basis for the optimization of Tuanjie polder in Nanjing.
