Finite element method for simulation of tsunami run-up from quikibird satellite data

Abstract

In this paper, work was carried out to simulate three - dimensional (3 - D) tsunami run - up from high resolution remote sensing satellite data of QuickBird. In doing so, the tsunami wave spectra are extracted f rom QuickBird data using two dimensional di Fourier transform (2 - DFFT). The tsunami propagation equation was then solved based on the standard Galerkin finite element approach to simulate 3 - D tsunmai run - up. The results of this study have shown that the in tegration between different mathematical and numerical models is providing accurate 3 - D reconstruction and simulation for tsunami run - up.
