2 | This section deals with modelling the damage to infrastructure as a result |
---|
3 | of the inundation described in the previous sections. |
---|
4 | The National Building Exposure Database (NBED) has been |
---|
5 | created by Geoscience Australia so that consistent risk assessments for a range |
---|
6 | of natural hazards can be conducted |
---|
7 | \footnote{http://www.ga.gov.au/urban/projects/ramp/NBED.jsp}. |
---|
8 | The NBED contains information |
---|
9 | about buildings, people, infrastructure, structure value and building contents. |
---|
10 | It is important to note here that the NBED contains information about |
---|
11 | residential structures only. |
---|
12 | |
---|
13 | Once the maximum inundation is calculated for each building, the resultant |
---|
14 | damage |
---|
15 | can then be determined as a function of its type and location from the |
---|
16 | coastline, \ref{ken:damage}. |
---|
17 | |
---|
18 | Impact on indigeneous communities are important considerations when determining |
---|
19 | tsunami impact, especially as a number of communities exist in coastal regions. |
---|
20 | These communities are typcially not included in national residential |
---|
21 | databases and |
---|
22 | would be therefore overlooked in damage model estimates. |
---|
23 | There are four indigeneous communities located in this study area as seen |
---|
24 | in \ref{fig:communities}. The community located in a potentially vulnerable |
---|
25 | position |
---|
26 | (on the headland) is Tjalka Boorda whose population is not registered. |
