Numerical Simulations of Three Dimensional Current Coupled With Wave in the Near-shore Area and Its Application Research on Pollutant Transport

摘要

In this paper, firstly, the module of depth–dependent radiation stressesrnis introduced into COHERENS-coupled hydrodynamical ecologicalrnmodel for regional and shelf seas . Secondly, a three dimensionalrncurrent model of Bohai bay is set up and used to simulate the pollutantrntransport of a certain pollution outlet in costal Bohai bay.The majorrnconclusions as following: coupling wave with current should be tookrninto account in the study of current or pollutant transport in coastalrnzone. With the coupled wave and current, flow field will have a greatrnchange and the dispersion of pollutants will be more severe in thernnearshore.
