Operational Coastal Modeling System of Korea

Abstract

We have developed a down-scaled high-resolution operational coastal modeling system for the coastal waters of Korea to support the major ports of Korea. For the operation of this system, we use a high-resolution coastal modeling system with 300 m grid size, for the western ports of Incheon and Gunsan, and southern ports of Yeosu, Masan, Busan, and Ulsan. The modeling system consists of operational coastal modeling and web-GIS modules. The modeling system uses a Regional Ocean Modeling System (ROMS), which is coupled with wave model SWAN using Model Coupling Toolkit (MCT), to exchange data fields between the ocean model ROMS and wave model SWAN. The wave-current coupled model ROMS-SWAN is internally nested with the Community Sediment Transport Modeling System (CSTMS), and is externally nested with the water quality model CE-QUAL-ICM. For the surface forcing, we use predicted results derived from an operational atmospheric model WRF, which has been operated for the East China Sea and East Sea. 300 m grid size, for the western ports of Incheon and Gunsan, and southern ports of Yeosu, Masan, Busan, and Ulsan.
