지진해일에 의해 발생되는 유사흐름으로 인한 해저지형의 변화

초록

Tsunami, one of the major natural disasters, is rapidly invaded the coastal communities resulting in significant casualties of humanbeings and property damage. In addition, because tsunamis may have a great amount of energy, they transport various floating debrisand silt resulting a deformation of the coastline and a damage to structures. Therefore, predicting the sediment transport caused by tsunamiis also important as much as expecting the inundated area due to flooding. In this study, a numerical simulation is carried out topredict the morphological change of the sea bed considering the domain, where sediment transport occurs, into two layers; bed loadlayer which is made up by bed load, and suspended load layer mainly composed by the movement of the suspended load.
