Abstract
The seismic response from the marine bottom is numerically simulated. Acoustic equations are used to describe the dynamic behavior of a water layer. Bottom sediments are described as a porous fluid-filled medium by using the Dorovsky model. A unified algorithm for full wave modeling based on the grid-characteristic method is proposed for solving all hyperbolic systems of equations in the entire computational domain. A distinctive feature of this approach is that the necessary contact conditions at the interface of media with different rheology are set in explicit form.
