Abstract

Abstract: The hydrodynamic environment and the salinity field distribution around Liuheng Island are simulated with a 3D current-temperature-salt numerical model and the simulation results are verified with the field data, which shows the computation results are able to reflect the hydrodynamic characteristics and the salty-field objectively. Base on this 3D numerical model, the salinity field distribution after the discharge of the concentrated brine from seawater desalination is calculated and compared with the salinity field distribution before the discharge. The results show that the influence of concentrated brine discharge is mainly centralized at the bottom water layer in a zonation distribution near the outlet around where the salinity is stratified in vertical and the maximum increment of the salinity is about 1.2.

Key words: strong brine, seawater desalination, mathematic simulation, Liuheng Island
