RUN-UP OF TSUNAMIS BY LINEAR AND NONLINEAR THEORIES

Chiaki Goto, Nobuo Shuto

Abstract


Linear and nonlinear sets of equations of long waves in the Lagrangian description are solved numerically to obtain run-up heights. Numerical results are compared -with theoretical ones in case of simple topographies and the agreement is quite satisfactory. As a practical application, the computation is carried out for the Okkirai Bay in Japan. The computed run-up neighs agree fairly well with the recorded ones.
