초록
An Island type reclamation for the construction of industrial complex and harbor structures has been worked at the south-west part of Gwangyang Bay. It was generally known that waterways along the dyke of island type reclamation had higher speed tidal flows and better tidal circulations than those of other structures. However, almost all the data did not sufficiently descript these phenomena and quantitative assessments were still lacking. Therefore, in this study, tide and tidal current were observed in the interesting area and some numerical simulations had been conducted in order to predict flow field and tidal exchange. A three dimensional hydrodynamic model considering wetting and drying with moving boundary scheme had been employed for the computation of a flow field. A particle tracking model had been also simulated for tidal exchanges in terms of the Lagrangian method. As a result, the most strong current speed after reclamation works decreased a great deal over the whole area. The tidal exchanges after all reclamation works, and also, were worse. On the other hand, the tidal exchange by island type reclamation showed more increased tendency about 1～5% than that of complete reclamation.
Abstract
An Island type reclamation for the construction of industrial complex and harbor structures has been worked at the south-west part of Gwangyang Bay. It was generally known that waterways along the dyke of island type reclamation had higher speed tidal flows and better tidal circulations than those of other structures. However, almost all the data did not sufficiently descript these phenomena and quantitative assessments were still lacking. Therefore, in this study, tide and tidal current were observed in the interesting area and some numerical simulations had been conducted in order to predict flow field and tidal exchange. A three dimensional hydrodynamic model considering wetting and drying with moving boundary scheme had been employed for the computation of a flow field. A particle tracking model had been also simulated for tidal exchanges in terms of the Lagrangian method. As a result, the most strong current speed after reclamation works decreased a great deal over the whole area. The tidal exchanges after all reclamation works, and also, were worse. On the other hand, the tidal exchange by island type reclamation showed more increased tendency about 1～5% than that of complete reclamation.
