Coastal Modeling System using GOCI Satellite Data

Abstract

Down-scaled 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 such as surface elevation, currents, storm surge height, temperature, salinity, and sediment transport from ROMS, wave information such as wave height, wave direction and wave period from SWAN and water quality parameters such as chlorophyll, dissolved oxygen, phosphorus, nitrogen etc. from ICM. The wave and hydrodynamic information is now operational for the forecast of the coastal waters of Korea twice a day in the 72 hours base. The coastal information system which is based on web-GIS system provides the predicted results with real-time monitoring data for dissemination to the public and validation of the operational model using various visualization techniques. 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 usager (GOCI) data.
