Storm Surge in Estuary
In this study, we modeled tides and storm-induced surges around Korean Peninsula, with a focus on riverine discharge effect. The additional inclusion of riverine-discharge effect into simulation is made to improve the prediction accuracy. Delf3D-Flow was utilized for hydrodynamic part and HEC-HMS was adopted for hydrological part. Since Delft3D is quite open to accommodate the indirect flooding factors such as riverine discharge and short waves, outer-coupled modeling system was established to account for combined tide-surge-riverine flow effects. The marginal contribution of riverine discharge on the flooding area (or depth) was assessed by comparing tide-surge with tide-surge-riverine discharge simulation.
