- Abstract
- The generation and propagation of tsunamis occurring in coastal regions between November 1977 and April 1980 are analyzed. Focus is on three subject areas: (1) the generation of water waves by three-dimensional bed motion; (2) a viscous model for nonlinear dispersive waves; and (3) the propagation of linear periodic waves over submarine trenches. The experimental design for each phase is presented including its problem formulation and both theoretical and numerical analyses. Results of the first part show that three-dimensional water surface profiles deviate significantly from two-dimensional water profiles.
