Simulation of Salinity Changes Induced by Man-Made Sea Embankment

Article Preview

Abstract:

Understanding the salinity transport mechanism in the estuaries is of great importance for coastal engineering, disaster prevention, water security and intertidal zone aquiculture.In this paper,the large-scale sea embankment in the Oujiang River Estuary (ORE) of Wenzhou shoal was taken as an example.Based on the intoduction of the study area,the 3D marine numerical model (EFDC) was setup and used for simulation of salinity changes induced by the embankment. The results indicated that the ORE is well-mixed estuary. The Ling-Ni Embankment designed in accordance with the flow direction makes the freshwater inflow reach far away, the salinity gradient increase, and the tongue contour reach further. The salinity difference of the north and south side of the embankment sea area is increased.
