Two-dimensional, time-dependent, nonlinear, incompress ible, viscous flow calculations of realistic models of tsunami waves interacting with continental slopes and shelves were performed. Wave heights were observed to grow by a factor of 4 as they shoaled up a 1: 1; continental slope. The second or third wave often exhibited the largest wave run-up. Comparisons with shallow water, long-wave calculations showed similar results except for short wavelength tsunamis. The damping action of submerged barriers on tsunami waves was investigated. Significant amounts of the energy of a tsunami may be reflected by submerged barriers. The numerical simulation of tsunami waves can provide realistic descriptions of their flow. (auth)
