Studies on Improvement of Costal Flow and Suspended Solid Predictions in the Coastal Zone Developments
In order to direct the reasonable preparation of Environmental Impact Assessment(EIA) reports and eco-friendly development of projects which give impacts on coastal zone, we found problems on the impact prediction of coastal flow and suspended solids(SS) based on existing EIA reports and suggested the guidelines for the reasonable improvement for the problems through qualitative experiences, quantitative modeling, and foreign case study. The content of the present study includes 1) investigation of coastal flow and SS phenomena, 2) analysis of status and problem for the existing ocean-related EIA, 3) foreign case study such as USA and Japan, and 4) improvement direction of coastal flow and SS predictions in EIA process.
The dynamics of coastal processes include coastal flow regimes, weather system, sedimentation transport as well as hydrological link between coast and its boundary. The processes in the coastal zone link all factors physically and biogeochemically, and thus influence the ecosystem in the area. The major flows involved into the processes are tidal flow, wind-driven, density-driven, and wave-driven currents, which influence the biogeochemical system of coastal zone through advection and diffusion processes. Previous fifteen Environmental Impact Assessment reports, mainly for the harbor development, are selected with regional consideration along the coast of Korea and analysed for prediction processes on coastal flow and suspended solid(SS), We found
