Реферат: eng: In this paper we describe results obtained in numerical investigation of the mechanism of tsunami generation by a moving submerged landslide which is simulated by a solid body sliding down a slope. The authors perform complex multiparameter calculations by algorithms based on the hierarchy of wave hydrodynamics models comprising shallow water equations and full hydrodynamical equations of an ideal fluid. We investigate the crucial dependences of the wave formation process on the length and thickness of the landslide, its bedding depth, and the law of motion. A comparison of solutions obtained by the approximate and full models allowed us to assess the degree of impact of the vertical flow structure and specify the domain of applicability of the approximate models.
