The NSW Office of Environment and Heritage has commissioned UNSW Water Research Laboratory (WRL) to complete a hydraulic and cost benefit assessment of the impact of climate change on the Hunter Valley Flood Mitigation Scheme (Scheme). The objectives of the study are to:

  1. Assess the current state of flood protection provided by Scheme infrastructure;
  2. Provide options and recommendations for the ongoing management of the Scheme to maintain the flood mitigation function as fit for purpose, considering the potential impacts of climate change;
  3. Evaluate the economic, social and environmental benefits and costs of the current scheme, and options and recommendations for its ongoing management.

Study outcomes will directly inform a broader strategic review of the HVFMS currently underway to improve understanding of the role of the Scheme; the impacts and costs of a range of flood events on the existing and future community; the impacts of climate change on flood risk and sea level rise, and the implications for the level of protection provided; to identify priority, at risk and potentially redundant components of the Scheme; and to provide recommendations for future investment or management.


Workshop Purpose

To provide Councils with information on the broader review of the HVFMS and to facilitate input to the current cost benefit study underway, focusing on areas around risk and risk mitigation.
