Abstract |
The aim of this study is to give an overview of existing oil spill models that deal with the physical, chemical and biological aspects of fate/behavior of spilled oil, and to develop a feasible, sophisticated, design purpose model of oil spill in the coastal waters. The processes of oil weathering and movements are reviewed in detail, and the characteristics of existing oil spill fate and behavior models are examined and classified, so that an ideal model may be defined. After the evaluation of the existing models, a new model which can be practically applied to the coastal waters are developed considering meteorological and hydraulic factors in the coastal waters including advection and weathering mechanisms summarized in the review work. The wind field effect including land-sea breezes near the coastal area are considered by the comprehensive 3-D meteorological model. The oil-holding capacity and removal coefficient as well as the wave and current dynamics near the coast are included. Other parameters which may affect the advection and weathering of spilled oil are considered as same as in the typical conventional oil spill models. The applicability and feasibility of the model are discussed by comparative applications of the typical conventional model and the developed model to the South-East Coastal Waters of Korea. |
