Abstract

The tsunami wave, approaching to river entrance, is related with various river characteristics. In wave propagation process, river mouth morphology is one of the dominant factors because it is first the feature of the river when the tsunami wave arrived near rivers. At the tsunami wave generated by the 2010 Chilean Earthquake, the field observation data indicated a different aspect of wave propagation according to the river entrance structure. In this study, in order to evaluate the influence of tsunami wave due to river mouth morphology, a numerical experiment was conducted for hypothetical cases are based on the representative river mouth type. The results of numerical simulation and analysis of measurement applied to the effect of tsunami wave by the change of the river mouth.
