The purpose of the investigation was to establish regional hydrology and flooding constraints of the Weddell region of the Litchfield Shire, for land use planning and counter disaster management purposes.

The summation of errors from all sources results in data with a standard deviation defined by scale used as +/-25m for well-defined points.0not knownHigh0The Q100 and PMF datasets produced were a product of the Elizabeth and Blackmore Rivers Flood/Floodplain Model developed by Cardno in April 2014. A high resolution 1:10,000 scale dataset that details the extents of flooding for a predetermined flooding frequency (usually 1% annual exceedance probability), with peak flood height contours, and floodway derived from hydrologic model URBS (Version 4.00), utilising the split runoff routing model and hydraulic model TUFLOW (Version 2012-05-AE), a linked 1D/2D hydrodynamic modelling package 2D floodplain model) using topographic mapping (2009 LiDAR) and flood event flow dataset. The mapping dataset is displayed over a topographic/cadastre base and is mainly used for planning purposes to provide a basis for identifying the extent and distribution of flood levels at a predetermined return period for the area.
