The Evaluation of Water Quality in Shallow Water Using the 3D Physical-biochemical Coupling Model

摘要

Recently, pollution by development in coastal areas is going from badrnto worse. Thus, the Korean government tries to solve these problemsrnthrough policies that prevent water pollution; however, it is stillrndifficult to mention whether such measures are lowering pollution to anrnacceptable level.rnIn this paper, we simulated the rates of dissolved oxygen (DO),rnchemical oxygen demand (COD), total nitrogen (T-N), and totalphosphorousrn(T-P) using the ecosystem model which is a combinationrnof the 3-dimension hydrodynamic model and the material cycle model,rnwe did simulations using a specific set of parameters and didrncomparative analysis to determine those most appropriate for the actualrnenvironmental characteristics of Ulsan Bay.rnThrough the simulation was successful, making it now possible tornpredict the likelihood of coastal construction projects causingrnecological damage, such as eutrophication and red tide. Our model canrnalso be used in the environmental impact assessment (EIA) of futurerndevelopment projects in the ocean.
