- Abstract
- A second-order upwind scheme is employed to predict the run-up heights of tsunamis in the East Sea and the obtained results are compared with the available field observed data and numerical results of a first order upwind scheme. In the numerical model, the governing equations solved by the finite difference scheme are the linear shallow-water equations in deep water and the nonlinear shallow-water equations in shallow water. The target event is the 1983 Central East Sea Tsunami recorded as the most devastating tsunami in Korea. The predicted maximum run-up heights agree reasonably well with field observations.
