In work is considered numerical solution of a task about distribution superficial waves in a liquid layer on the porous basis. Expressions for the decrement of attenuation and frequency of fluctuations of a wave are written. Dependences of frequency of fluctuations of a wave on dimensionless sizes are shown. Various special cases are considered. The dispersive equation for the infinite thickness of a layer of the porous environment is written.

Keywords: porous environment, frequency of fluctuations of a wave, decrement of attenuation of fluctuations of a wave, rhombohedral packing of balls of the porous environment
