This paper addresses numerical modelling of wave regimes generated by the movement of underwater landslide on a curvilinear bottom. Our work differs from the works of other authors, where the problem of wave generation by a moving landslide has been investigated on flat bottoms only. The equations, describing the movement of an underwater landslide under the action of gravity force, buoyancy force, friction force and water resistance force, are obtained. Dependence of the arising wave properties versus the initial embedding of a landslide, its dimensions and slope of a bottom is investigated. Modelling of the surface waves, arising due to the movement of an underwater landslide on irregular bottom, was carried out in the framework of the shallow water model using the predictor-corrector scheme on an adaptive grid.
