Numerical Study on Transport of High Concentration Suspended Sediment Water in Artificial Seawater Lake

The sea water near the estuary of Yangtze River is high in sediment concentration and low in transparency. Clear coastal water can be found in artificial sea lakes, which are isolated from outer sea water by reclamation projects in the intertidal zone. But the water supplied by sea for the artificial lake exchanging is still a big problem. Transport of high concentration suspended sediment (SS) water in artificial seawater lake is studied. The water supplied from the small lake (sand basin) cannot meet the requirements of the landscape and recreation needs of the big lake, as the SS concentration is 0.2 kg/m(3). After adding the ecological barrier in sand basin, the SS concentration of most water area in big lake is below 0.1 kg/m(3). This idea can be used as reference for water quality control of seawater artificial lake.
