Abstract
The numerical simulator (STOC) has been developed to estimate tsunami damage on coastal areas in which there are lotsof structures. STOC consists of two sub-models: three-dimensional and non-hydrostatic model (STOC-IC) and multilayerhydrostatic model (STOC-ML). The present model, especially STOC-IC is validated by experiments on flowaround a rectangular weir and tsunamis passing a tsunami breakwater. In addition, applying the combination model of STOC-IC and STOC-ML to tsunami simulation in actual topography of harbor, it confirms that non-hydrostatic phenomenaappear around seawalls and bending section of channels.
