Two-dimensional bending-gravitational waves in the sea covered with ice

Applied hydromechanics, Vol. 11 (83) ¹ 1, (2009) p.73-76
The general Kadomtsev-Petviashvily-type equation describing propagation of long non-linear flexible-gravitational waves in the sea, covered with ice, has been developed. The equation has been constructed with the taking into account the geometrically-nonlinear flexion of the thin plate, which simulates the ice cover. It must influence the intervals where the equation solution exists.
