Abstract

We developed a hydrostatic three dimensional numerical model, which was applicable to analyses of tsunami scours and depositions in harbors. The model can explicitly estimate vertical distributions of suspended sediment concentration, which would be important to predict the tsunami deposition precisely. In order to validate the model, we carried out the test simulations; the long-wave propagations over a flat wall, and the development of suspended sediment concentration profiles in a steady homogeneous flow over a sand bed with initially clear water. The numerical simulation of tsunami scour and deposition in an idealized harbor was also carried out, and we compared our numerical results with the laboratory experiment. As a result, we confirmed an agreement among them.
