Fitzroy River 2D Flood Modelling

Project: Fitzroy River 2D Flood Modelling
Client: Main Roads Western Australia

BG&E were commissioned to provide specialist flood modelling services in support of the upgrade of the Great Northern Highway near Fitzroy Crossing in the Kimberley region of Western Australia.

The key objectives of the study included:

  • 2D Flood Modelling of the confluence of The Fitzroy River and Margaret River near Fitzroy River.
  • Development of an integrated 1D-2D floodplain model using MikeFlood (DHI) software.
  • Calibration of the 2D model with recorded flood data at various sites including remote indigenous communities.
  • On-going waterways design support for the upgrade of the Great Northern Highway.
