摘要/Abstract

摘要： 采用三维潮流温盐数学模型对六横岛附近海域的水动力环境及盐度场分布进行数值模拟,并以实测资料进行验证,所建立模型可以较好地反映该海域潮流动力特征及盐度场的分布情况。利用验证后的三维数学模型,对海水淡化工程浓盐水排放后盐度场分布进行计算,将排放后的盐度分布与工程前进行对比分析,并推算盐升面积及垂向盐度增量。结果表明,海水淡化工程排放的浓盐水对六横岛海域盐度分布的影响主要集中在排水口附近的底层,影响区域呈带状分布,最大盐度增量为1.2左右,且排水口附近海域出现盐度垂向分层。

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.
