Run-up Heights of Tsunamis for Geometric Variables

Abstract

Since many islands are located in the South Sea of the Korean Peninsula, unexpected tsunamis could cause devastating damage. To investigate the effects of geometric variables on the maximum run-up heights of tsunamis, a numerical model is first employed. The model is based on the nonlinear shallow-water equations with a moving boundary treatment along the shoreline. The numerical model is then applied to simulation of maximum run-up heights of tsunamis approaching on islands with variable geometric conditions. The obtained numerical results can be used to a defense plan of islands in the case of real tsunami attacks.
