Investigation of solutions of the shallow water equations in the vicinity of the mobile run-up line
Solutions of initial-boundary problems for the shallow water equations are constructed in the form of rows, which locally converge in the vicinity of the mobile dry-wet boundary for any bottom topography. The law of motion and the velocity of this boundary are defined for various conditions of wave-coast interaction. The obtained analytical results are used for development of new approximations of boundary conditions at the mobile run-up line. Results of the numerical solution of the test problems are presented. We use the second order explicit predictor-corrector scheme on the adaptive grids, which trace the position of the dry-wet boundary
