Tsunami Modelling Methodology Validation: GERALDTON


Introduction

The information within this DVD is the result of a validation study of Geoscience Australia's tsunami modelling methodology. This has involved the development of methodologies for modelling tsunami generation, propagation and inundation. The work reported here validates the tsunami modelling methodology against observational evidence of the 2004 Indian Ocean Tsunami. Results from deep water propagation modelling using the URSGA model are compared with satellite altimetry from Jason-1. Time series from the URSGA model are used to drive the ANUGA hydrodynamic model to simulate onshore inundation for Geraldton, Western Australia. Inundation results are compared with observational data including tide gauge records obtained from the Department of Transport in Western Australia and field observations collected by Guria Consulting.

While the associated report provides background, model results and interpretations, the DVD contains all data, scripts and instructions for installing software necessary to reproduce and potentially augment the ANUGA inundation model underpinning the report. This includes modelled time series of the 2004 tsunami along the entire Western Australian coast. This allows other users both to rerun the inundation model to test the validation and also to potentially run simulations for other Western Australian locations.

The data provided on this DVD is:
