Abstract:
In the present paper, the numerical algorithm for the hydraulic bore propagation onto a dry channel on the basis of the shallow water equations is proposed. This algorithm is based on a modified total momentum conservation law. The results of numerical simulation of generation, propagation and run-up onto the inclined shore of the hydraulic bore, arising after the total or partial (in the two-dimensional case) dam-break, and of the wave like tsunami, arising after a quick local bottom rise.
Key words:the theory of shallow water equations, hydraulic bore, dry channel, inclined shore.
