Research on Planning Design and Application of Water Diversion and Distribution of Urban Rivers
The"Five Water Co-governance"(FWC),which includes sewage treatment,flood control,drainage,wa-ter conservation and water saving,act as the breakthrough to pushback the transformation mechanism.It is the key strategy to promote the new round of reform and development in Zhejiang.With the increasing requirements for water environment improvement of FWC,the important measures of water diversion and distribution of urban rivers have become increasingly prominent and caused various associated problems.In view of the problems existing in the cur-rent situation of water diversion and distribution facilities in urban rivers of Hangzhou,the influencing factors are analyzed.Combined with the actual geographical environment,the planning and design ideas are put forward.The river network flow field is calculated by constructing and verifying the hydrodynamic model and water quality model.The water flow control direction of each river is clarified by partition.The planning and application results are tracked and analyzed.The results show that the improved effect of water diversion and distribution planning scheme has been seen in project implementation,water diversion ratio and water quality,which provides reference value and ideas for urban river management in future.
