Map shows three flood models for 5, 50 and 500 year probability events for planning purposes. The 90-metre resolution Digital Elevation Model (DEM) available for the study for the affected area was the Shuttle Radar Topography Mission Digital Elevation Model (SRTM DEM). Flood extents and flood depths were derived by performing one dimensional hydraulic routing through the Shire River system for key return period discharges; and these were validated using satellite images of recent flood events.
