The potential impacts of climate change are an issue that must be addressed for all projects relying on hydrological assessment, from flood studies and flood risk management planning to infrastructure design, coastal development, and water supply management. WMAwater have assessed the impacts of climate change on a range of studies and are familiar with state government policy and current research.

WMAwater are aware of the impacts of climate change on both catchment characteristics as well as boundary conditions, such as ocean levels, storm surge and rainfall intensity. WMAwater has also been engaged to extend previous studies to investigate the impact of climate change.

Mark Babister is chair of the Australian Rainfall & Runoff (AR&R) committee on Climate Change. The committee includes representatives from Bureau of Meteorology, CSIRO, Federal Department of Climate Change and Energy Efficiency, universities, state agencies and practitioners. The aim of the committee is to develop a national approach for incorporating climate change. This committee will be responsible for a national recommendation on how IFD will change with climate change.

A WMAwater team lead by Mark Babister and Richard Dewar investigated the impact of climate change on a state wide and case study basis for DECCW. Mark, Richard and fellow Director Graeme Hurrell have all published on the impact of climate change on flooding and ICOLLs.

Other examples of recent projects where climate change has been a key factor include:

  • Hawkesbury Nepean Climate Change Assessment;
  • Shoalhaven;
  • North Creek;
  • Kempsey/Macleay River;
  • Kurnell;
  • Bellinger, Kalang and Nambucca Rivers.
