The problem of the numerical simulation of the seismic response from the marine bottom is considered. Acoustic equations are used for the description of the water dynamic behavior. Bottom sediments are described with the porous fluid-filled medium. The Dorovsky model is used. The algorithm for solving all hyperbolic equation systems with the grid-characteristic method was proposed. The distinctive feature of this approach is the ability to set explicitly necessary contact conditions between media with different rheology.
