Abstract

When a tsunami has a large source area it may be the case that important wavelengths of the resulting tsunami wave are in the shallow water domain (i.e. wavelength is greater than 20 times the water depth). In this case TELEMAC-2D should be suitable. If shorter wavelengths are important then the best approach could be to use TELEMAC-3D non-hydrostatic. TELEMAC-2D should be tested for ability to model wave propagation correctly as well as diffraction and refraction phenomena. In this case, it is not expected that the inundation behaviour will be represented in the same model as the propagation to near shore is modelled using the wave equation formulation in TELEMAC-2D and the inundation phase (if required) will use the finite volume (kinetic scheme) in TELEMAC-2D. So it is important to find analytical or laboratory test cases that are within the shallow water equations’ limit of validity. Some such test cases have been identified and the performance of TELEMAC-2D in comparison is presented in this paper.
