Abstract
Combining 2-D numerical models and 1-D analytical runup theory, we proposed a novel and rapid method for forecasting tsunami runups on the coasts. In the first step, the 2-D numerical simulations of tsunami generation and propagation are performed assuming impermeable boundary conditions of a 5–10m depth at the last sea points (equivalent to a wall). Then the time series of the water oscillations on the wall are used to calculate the runup heights using the analytical integral expression following from 1-D theory. We have demonstrated that the proposed approach is a more reasonable and rapid method of forecasting than complicated coastal inundation models. This new method can also be applied to other regions.
