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

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

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