Formulation of the Problem

Figure 2
[8]  We consider a problem of long wave generation by a dynamic source and their propagation with account for real bathymetry of the Black Sea in two-dimensional formulation. Spatial variables are x, y, and z, the Ox axis is directed to the shore (Figure 2). The system of coordinates is oriented so that axis Oz is directed vertically upwards, and non-perturbed sea level coincides with yOx plane.

[9]  Here, u(x, t) is horizontal velocity component; h (x, y, t) is perturbation of the free surface; H is maximal depth of the basin; B(x, y, t) is variation in the bottom of the basin; Hast is depth at the 10-meter isobath.

[10]  Dynamic seismic source in the form of key-blocks, which can rise (or descend) to a given distance with different velocity, was used for tsunami wave generation [Lobkovsky and Baranov, 1984]. At the initial time moment, parameters of dynamic seismic source (coordinates, velocity of the vertical motion of key-block) are specified in the calculation area. The boundaries are located either in the land regions or the water surface.
