Abstract
Due to the earthquake or the active vocalno at the ocean, the seabed surface at the steep slope may slide down that induces tsunami. Tsunami generated in the deep water area has the initial small amplitude, but it can propagate very quickly, without energy loss. Especially when it meets the shore line, the wave height may be increased quickly then causes the disaster problem. The submarine landslide-induced tsunami is the complicated inter - connected phenomenon between sedbed energy and water wave energy. In this study, the integrated model is introduced to simulate submarine landslide using the nonlinear shallow water equations and tsunami using the extended Boussinesq equations including the bottom - varying in time and space. The result of one - dimensional integrated model of submarine landslide - induced tsunami is verified to the experimental data.
