Coupled storm surge and wave simulations for the Southern Coast of Korea

摘要: An integrated model system was developed to apply surge-wave coupled simulations the southern coast of Korea during Typhoon Sanba in 2012. Numerical experiments were carried out examine effects land-dissipated wind on storm surges and influence wave-surge surface waves. These numerical used a finite volume ocean model, FVCOM, with wave SWAVE. Due complex geometry coastal area investigated, high-resolution terrain-following unstructured grid employed. Atmospheric forcing generated by planetary boundary layer which revised incorporating effect land’s roughness typhoon wind. A detailed comparison shows generally good agreement between measured simulated wind, surge, In particular, improved results have been found for simulation winds when considering addition, clearly obtained adding coupling waves surges. The show maximum contribution ~40% waveinduced surge peak height along coasts. mean rate error heights decreased from 29.6% 21.3% after dissipation, again 17.9% imply that dissipation caused land should be taken into account determining heights. also wave-current influences generation However, magnitude this relatively insignificant.
