Abstract:The river network is dense, the water system is interlaced and the hydrodynamic conditions are complex in Gaolan Port Economic Zone. The river channels take into account the multiple functions such as flood discharge, tide absorption, waterlogging drainage and improvement of urban ecological environment. At the same time, the water system, lake, river, bay and sea blend in this area. The operation scheduling of water conservancy projects such as sluices and pumping stations in this area has a great impact on the change of hydraulic power. In order to further implement the concept of green development, promote the construction of water ecological civilization, effectively maintain the healthy life of rivers and lakes, and perfect the water management system, the regional water system layout is studied and perfected, the regional flood control and waterlogging drainage capacity are improved, the scheduling scheme of water conservancy projects is adjusted, the layout and scale of various water conservancy facilities are optimized, and the vitality of river surges is recovered, which can provide the references for the other river network areas.
