Abstract

The problem about a flow of ideal incompressible nonviscous gravitational liquid over the plane is considered. The special attention is paid to waves with an amplitude close to maximum (Stokes's wave). Numerical research and extrapolation of results of calculations on the basis of a numerical filtration for an estimation of asymptotic parameters is carried out. The examples of application of the offered filtration methods given in the work show their efficiency.
