[3064] | 2 | This section deals with impact modelling which covers damage |
---|
| 3 | modelling and economic impact analysis. |

---|
| 5 | Damage modelling refers to damage |
---|
| 6 | to infrastructure as a result |
---|
| 7 | of the inundation described in the previous sections. The infrastructure |
---|
| 8 | refers to residential structures only and is sourced from the |
---|
| 9 | the National Building Exposure Database (NBED). The NBED has been |
---|
[2950] | 10 | created by Geoscience Australia so that consistent risk assessments for a range |
---|
[3064] | 11 | of natural hazards can be |
---|
| 12 | conducted\footnote{http://www.ga.gov.au/urban/projects/ramp/NBED.jsp}. |
---|
| 13 | It contains information |
---|
| 14 | about residential buildings, people, infrastructure, |
---|
| 15 | structure value and building contents. |
---|
| 16 | From this database, we find that there |
---|
[3024] | 17 | are 325 residential structures and a population of approximately 770 |
---|
[3078] | 18 | in Onslow \footnote{Population is determined by census data and an ABS |
---|
| 19 | housing survey}. |
---|
[2950] | 20 | |
---|
[3017] | 21 | Once the maximum inundation is calculated for each building, the resultant |
---|
| 22 | damage |
---|
[3064] | 23 | can be determined as a function of its type and location from the |
---|
[3017] | 24 | coastline, \cite{ken:damage}. |

---|
[2950] | 28 | Impact on indigeneous communities are important considerations when determining |
---|
| 29 | tsunami impact, especially as a number of communities exist in coastal regions. |
---|
[3064] | 30 | These communities are typically not included in national residential databases |
---|
[3004] | 31 | and would be therefore overlooked in damage model estimates. |
---|
[2950] | 32 | There is one indigeneous community located in this study area as seen |
---|
[3064] | 33 | in Figure |
---|
[3079] | 34 | \ref{fig:points}. The population of the Bindibindi community is 140 |
---|
[3004] | 35 | and is situated in a potentially vulnerable location. |
