ON THE APPROACHES TO A NUMERICAL MODELING OF LANDSLIDE MECHANISM OF TSUNAMI WAVE GENERATION

ABSTRACT: In this work the results obtained in numerical studies of landslide mechanism of tsunami generation on the basis of a complex of multiparameter calculations with the help of algorithms, based on hierarchy of models of wave hydrodynamics, are presented. The dependences of the process of wave formation on length and width of landslide, on the depth of its bedding, on the law of motion and on the bottom slope angle are determined. The solutions, obtained on the approximate and complete models, are compared, the degree of in uence of vertical structure of ow is estimated, and the region of the applicability of the approximate models is determined.
