-The initial condition used for this scenario is 0m Australian Height Datum
-which is approximately equal to Mean Sea Level.
+As part of the CRA, it was decided to provide results for the
+extremes of the tidal regimes to understand the potential range of impacts 
+from the event. The Highest Astronomical Tide (HAT) and Lowest
+Astronomical Tide (LAT) are defined as 1.5m AHD and -1.5m AHD 
+respectively for Onslow, \cite{antt:06}, with Mean Sea Level approximately
+equal to 0m Australian Height Datum. These values are tidal
+predictions based on continous tidal observations from Standard Ports
+over a period of
+at least one year, with the Australian Hydrographic Service
+recommending this be extended to three years to capture
+changes to the mean sea level. Onslow is listed as
+a Standard Port. As an aside, current work at GA is
+extracting information from LANDSAT imagery to reconstruct the 
+tidal variations for various WA locations. Future modelling of
+these areas will incorporate this information.

+
+The initial conditions used for this scenario is then MSL, HAT and LAT.

 tidal effects (that is, the changes in water height over time for
