Operational coastal modeling system for the application of GOCI data

Abstract

High-resolution operational coastal modeling system has been developing for the coastal waters of Korea using a Regional Ocean Modeling System (ROMS) which will be used for the application of the Geostationary Ocean Color Imager (GOCI) data. The operational model ROMS is two-way coupled with wave model SWAN, internally coupled with sediment transport model CSTMS and externally nested with water quality model CE-QUAL-ICM. The system will predict the hydrodynamic information from ROMS, wave information from SWAN and water quality parameters such as from CE-CUAL-ICM. The system has been under developing but the hydrodynamic information is now operational for the forecast of the coastal waters of Korea twice a day in the 72 hours base. The hydrodynamic results have been calibrated with tidal surface elevation and verified with currents observed by bottom mounted acoustic current meter ADCP and AWAC data in the coastal waters of Korea. For the validation of predicted results we use real-time monitoring data such as remote Buoy system, ocean observatory Tower, and HF-Radar system. The suspended solid concentration image retrieved from GOCI which is a main payload for the satellite COMS will be used for the validation of the model prediction on the suspended sediment transport for the coastal waters of Korea. In this study, we will show the predictability of the operational coastal modeling systedata.
