In this article, tsunamis represented as solitary waves was simulated using the fully nonlinear free surface waves based on Finite Element method developed by Sriram et al. (2006). The split up of solitary wave while it propagates over the uneven bottom topography is successfully established. Wave transmission and reflection over a vertical step introduced in the bottom topography is in good agreement with the experimental results from Seabra-Santos et al. (1987). The wave transformation over a continental shelf with different smooth slopes reveals that the solitary wave reflection increases while the continental slope varies from flat to steep. The interaction of the solitary wave with a vertical wall for different wave steepness has been analysed. The reflected shape of the profile is in good agreement with the observation made by Fenton and Rienecker (1982) and an increase in wave celerity is observed.read more

Simulation of nonlinear free surface dispersive shallow water waves
TL;DR: In this article, the finite element method is used in the domain for the estimation of the velocity potential, while, a cubic spline approximation is used to recover the velocity, and further modification is carried out for the velocity recovery by using least square method to overcome the difficulties in the simulation of steep waves.

Effect of continental and nearshore slopes on tsunami height
TL;DR: In this paper, a numerical model study is carried out using shallow water equations that are solved using Crank-Nicolson finite difference approximation method on a staggered grid, where a rectangular solitary wave is considered to propagate over typical continental slopes and nearshore profiles available along the Indian coast.
