Research on Improvement of Water Environment in Tidal River Network Area Based on Mathematical Model——Taking Punandong Area in Jinshan District,Shanghai City as an Example
Development of plans for improving water environment in plain tidal river network areas involves multi-objective and multi-variable combinatorial optimization.With Punandong area in Jinshan District,Shanghai City as an example,through building up the hydrodynamic model,improvement in the hydrodynamic conditions and quality of water environments of small and medium-sized rivers in different engineering schemes and dispatching schemes was studied in this paper.The results showed that engineering schemes such as building additional discharge outlets in south Hangzhou Bay can increase the water intake and discharge of this area,and improve the hydrodynamic conditions of the rivers in southern and eastern areas.Flexible use of the water scheduling schemes can further improve the hydrodynamic conditions of the small and medium-sized rivers in different areas.
