Calculation of Ecological Environment Water Demand for Tidal River Section in Jiangsu Province:taking Sheyang River as an example
摘要
Abstract
The study focuses on the tidal section of Sheyang River in Yancheng,Jiangsu Province.A hydrodynamic-water quality-sediment coupling model suitable for Sheyang River is constructed to simulate the changes in water quantity,pollutant concentration,and sediment deposition.The constructed hydrodynamic-water quality-sediment coupling model is used to calculate the ecological water demand for river water quality compliance and erosion and sedimentation protection,and compared with the basic ecological environmental water demand calculated by the improved ecological hydraulic radius method.Finally,the ecological environmental water demand above and below the Sheyang River tidal barrier is determined.The research results indicate that the constructed hydrodynamic-water quality-sediment coupling model in the study area can effectively simulate the changes in hydrodynamics,water quality,and sediment deposition of the Sheyang River,meeting the requirements of simulation accuracy;The ecological water demand during the flood season above the Sheyang River sluice is 348 m3/s,and the ecological water demand during the non flood season below the sluice is 205 m3/s.The research results can provide reference for the ecological environment water demand accounting,ecosystem health protection and restoration of tidal rivers in Jiangsu.关键词
