|---|
| 25 | The information within this DVD is the result of a validation study of Geoscience Australia's tsunami modelling methodology. |
|---|
| 26 | The Australian Government Attorney Generals Department (AGD) has supported Geoscience Australia (GA) in developing a |
|---|
| 27 | range of products to support the understanding of tsunami hazard through the Australian Tsunami Warning System Project. This has involved the |
|---|
| 28 | development of methodologies for modelling tsunami generation, propagation and inundation. The work reported here validates |
|---|
| 29 | the tsunami modelling methodology against observational evidence of the 2004 Indian Ocean Tsunami. Results from deep water propagation modelling |
|---|
| 30 | using the URSGA model are compared with satellite altimetry from <a href="http://topex-www.jpl.nasa.gov/mission/jason-1.html">Jason-1</a>. Timeseries from the URSGA model are used to drive |
|---|
| 31 | the <a href="https://datamining.anu.edu.au/anuga">ANUGA</a> hydrodynamic model to simulate onshore inundation for Geraldton, Western Australia. |
|---|
| 32 | Inundation results are compared with observational data including |
|---|
| 33 | <a href="http://www.dpi.wa.gov.au/imarine/19383.asp">tide gauge records</a> obtained from <a href="http://www.dpi.wa.gov.au/">The Department of Transport</a> in Western Australia |
|---|
| 34 | and <a href="field_observations" >field observations</a> collected by Guria Consulting. |
|---|
| 35 | <p> |
|---|
| 36 | While the associated report provides background, model results and interpretations, the DVD contains all data, scripts and |
|---|
| 37 | instructions for installing software necessary to reproduce and potentially augment the ANUGA inundation model underpinning the report. |
|---|
| 38 | This includes modelled <a href="data/western_australia/geraldton_tsunami_scenario/anuga/boundaries/wa04_val">timeseries</a> of the 2004 tsunami along the entire Western Australian coast. |
|---|
| 39 | 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. |
|---|
| 40 | <p> |

| 41 | The data provided on this DVD is: |
|---|
| 42 | <ul> |
|---|
| 43 | <li> Geoscience Australia Record 2009/XX entitled <blink><i><a href="documents/Horspool_et_al_GA_record_2009_XX.pdf">Tsunami modelling validation: |
|---|

| 45 | <li> <a href="field_observations" >Field observations</a> collected from the Western Australian coast following the tsunami |
|---|
| 46 | <li> <a href="data/western_australia/geraldton_tsunami_scenario/anuga/outputs/2004_tsunami_validation">Model outputs</a> including: |
|---|
| 47 | <ul> |
|---|
| 48 | <li><a href="data/western_australia/geraldton_tsunami_scenario/anuga/boundaries/wa04_val">Mux files</a> containing timeseries of the tsunami for offshore Western Australia |

|---|
| 51 | <li>Combined <a href="data/western_australia/geraldton_tsunami_scenario/anuga/topographies">elevation data</a> used by the simulation. Bathymetry data was supplied by |
|---|
