Richmond River Flood Mapping

The Richmond River Flood Mapping Study was funded by the Richmond River County Council, Richmond Valley Council, and the NSW Department of Environment, Climate Change and Water in 2008 as part of the Flood Prone Land Policy of the New South Wales government.

It is the first of three studies on flood management in the Richmond Valley between Casino, Lismore, and Broadwater.

The study area includes the Richmond River, Bungawalbin Creek, Wilsons River, and major tributaries such as Shannon Brook and Sandy Creek.

The study resulted in a calibrated hydrologic model, a calibrated 1D/2D hydraulic model, and flood mapping for historical and design flood events.
