Abstract
In the paper the new method for numerical simulation of the long wave run-up process is proposed. Nonlinear shallow water equations are used for description of the wave propagation up to the water edge point. Then the special algorithm used for estimation of the flow parameters and the location of the moving water edge. It is based on the energy and mass conservation laws. Several series of one-dimensional computations were carried out. The shore profile, that gives the maximum run-up height for the fixed initial wave parameters have been found. Results of modeling of the tsunami run-up on the real shore in the Akita prefecture (Japan) are presented.

Key Words
shallow water equations, tsunami, long wave runup process, difference scheme
