Abstract: A Boussinesq-type model is developed for simulating wave and runup generated by sliding masses in the coastal region. A shock-capturing Boussinesq type model, which is originally designed for simulation of coastal water waves over fixed sea bottom, is extended to include the effect of time-varying bed. Landslide is then assumed as a rigid body without changing its shape during sliding. The governing equations are solved using a hybrid finite difference and finite volume method with shock-capturing ability. Moving shoreline is specially treated in the model. The resulting numerical model is particularly efficient and computationally robust. Numerous numerical experiments, including both 1DV and 2DH cases, are conducted for model validation and the computed results are compared against the analytical solution or experimental data.
