A Numerical Wave Simulation for Deformation of Bottom Topography

Tokuzou HOSOYAMADA

From a long time ago, Niigata prefecture is suffering from shore deformation and coastal erosion, mainly caused by wave induced currents. Countermeasures against these problems had been taken. To make such a countermeasure more effective, numerical simulation technique for waves, currents and shore deformation should be established. In this study, numerical wave simulation code with littoral drift is developed. The subject of the study is Niigata west coast. Numerical results for deformation of bottom topography with bottom sediment transport show qualitative agreement with knowledge obtained previously.
