Abstract
There are a lot of researches on the run-up of waves which propagate onto plain beaches. The results from them have been contributing to the estimations of wave run-up height for the real planning of maritime structures and the managements of coastal zones. Contrary to this, however, not enough knowledge has been given on the run-up phenomena of long-period waves on complex beaches, because of the difficulty of numerical simulations of breaking and run-upping waves and restrictions of experimental equipments for long-period waves.
Koshizuka has developed a numerical simulation method for breaking and run-upping waves on a beach, based on the particle analysis. This Koshizuka's method is applied to analyze the run-up height of long-period waves such as Tsunami or solitary wave. The results are verified by Synolakis's experimental data for the run-up heights for the plain beach.
