Abstract


Storm surges and high waves occur at the same time. Due to high tide and waves, water overflow and wave overtopping occur over the coastal levee. Numerical simulation based on the two-dimensional Navier-Stokes equations by using the VOF method, CADMAS-SURF, is applied. The overflow and overtopping calculated by numerical simulation is analyzed, the hydraulic characteristics of flow rate over the coastal levee are clarified.
