Research Abstract |
The occurrence of large disaster by a great tsunami and the frequent occurrence of coastal disaster by the global warming and coastal erosion are becoming actual. So, the improvement of damage predicting methods was tried for the preparedness of these disasters. About huge tsunamis, a rational method for predicting tsunami inundations, a simple method for evaluating destruction grades of buildings with main part sizes and an inundation depth, and an easy method for predicting the scour by a back flow were proposed. As for big waves, because there are many coastal dikes and seawalls destroyed by scour and suction, easy methods for evaluating the scour in the front of a dike or a seawall and the suction from those bodies, and a suction preventing countermeasure were proposed.
