(Lalitha Ramachandran) In 2011 we had
an extraordinary flood event
and it demonstrated, quite clearly, what we might be facing
in terms of future flooding with sea level rise
and increased rainfall.
The area traditionally floods because
we’ve built on swamp land,
so we get quite a bit of rainfall that doesn’t have anywhere to go,
and if the coastal conditions, like storm surge,
or a king tide cause some restrictions on the coastline
you tend to get flooding events.
So the flood modelling that we’re doing
is basically to get an idea of
what future flooding might look like for the city.
Other than doing that what we want to be able to do
with the CSIRO project is actually
start to model some of the solutions we’re thinking about,
in terms of future flooding
to see whether they’re effective.
(Mahesh Prakash) Essentially what
the program does is it
gets the information about the urban infrastructure,
things like the canal also the weather forecast data
and it comes up with a visual representation
of what might happen if there was flooding.
It also allows you to start putting in these mitigation options
and actually evaluating them to test what’s going on
before committing the money to actually build infrastructure.
(Lalitha Ramachandran) From the perspective of the average engineer,
or council decision maker,
it would be a really vital tool,
because it will actually assist us to
ascertain which solutions might be effective
for what scenarios and for what period.
That then gives us a relatively good
starting point for negotiating
what infrastructure needs to go down at what cost, when.
