An Operational Prediction System for Cohesive Sediment Transport in the West and South Coast of Korea

Abstract

An operational prediction system of suspended fine sediment transport has been established as a primary tool for coastal management. Various components of coastal models including coastal waves, tide, storm surge, and wave-induced circulation were taken into account for the accurate calculation of various processes involved in cohesive sediment transport especially during the extreme sea states. The system covers all coastal waters surrounding the Korean peninsula and for more detailed prediction of the near-shore area, a much finer grid model is nested to the whole area model. All models developed in this system were combined to allow easy testing and provide fast and accurate prediction. In this paper the results of a simulation test in the south-western coastal waters are shown and compared with field measurements.
