Abstract
KIM, CHANG S. and LIM, H. S., 2007. Safety criteria on water depth, offshore distance and dredging volume in marine sand mining operation in Kyunggi Bay, Korea. Journal of Coastal Research, SI 50 (Proceedings of the 9th International Coastal Symposium), 507 - 510. Gold Coast, Australia, ISSN 0749.0208 A model study to investigate the sediment transport and cross-shore sediment flux near the shoreline is conducted for a marine sand mining operation in Kyunggi Bay, Korea. A modelling effort using a 3-dimensional model, a wave model and a wave-current sediment flux model has been applied to the study area. The ROMS (Regional Ocean Modelling System), SWAN and the HARRIS and WIBERG (2001) model represent the basic modules of the 3-dimensional hydrodynamics, wave transformation in shallow water and sediment transport respectively. The goal of the current study is to estimate the cross-shore sediment flux to quantify the erosion vulnerability of the shoreline by imposing various dredging intensity as in real situation. Being the wave and current interaction considered, the sediment transport model adopts the outputs of ROMS and SWAN for any designated time and space in the computation field. The realistic hydrodynamic conditions and wave field obtained from 20-year wave statistics enhance the prediction of the erosion process according to the water depth, offshore distance from the shoreline and dredging intensity (volume and frequency etc).
