Wave Generation By Impulse Moving Of The
Bottom

Abstract
This paper presents a simple formulation of the wave generation problem by impulse
deformation of the sea bottom. The hydrodynamics problem is separated into three value
problems: two of them are time-independent problems of an impulse deformation of the
bottom for unmoving free surface and of given vertical velocity of the free surface for
unmoving bottom, the other one is a time-dependent problem of free boundary deformation
for the unmoving bottom. All these problems have been investigated numerically using the
Boundary Element Method. For comparison, the first two problems are solved analytically.
1 Introduction
A wave generation on the free surface by bottom movings connects with
one of the destroying natural phenomens known as tsunami. Tsunami
waves have at first comparatively not a large amplitude, that's why, it is
