Abstract

 In order to perform the large tsunami simulation effectively, multi-scale tsunami simulation having both advantages of two-dimensional tsunami analysis based on the shallow water equation and three-dimensional tsunami analysis is being developed. The authors have selected the three-dimensional particle method as three-dimensional analysis method and proposed a new boundary treatment which can manipulate measured values in the pre-analysis by two-dimensional tsunami analysis. In this study, a matrix array shaped virtual wave-making plate is enhanced as an improved boundary treatment method for multi-scale tsunami simulation within the framework of the particle method, and then the accuracy and adequency has been investigated through a three-dimensional numerical example. Finally, a three-dimensional tsunami run-up simulation, in which the inflow condition is given by a two-dimensional shallow water solution, is conducted at Minami-Sanriku-cho in the 2011 Tohoku earthquake tsunami by using proposed method in order to validate the accuracy.
