WMAwater has extensive experience in catchment flood investigations and floodplain management, being at the forefront of the NSW floodplain management process since the initial stages of its development in the early 1980’s. Our credentials and track record in carrying out flood-related studies as well as producing practical floodplain management plans is significant. We constantly review and update our methodology to use the latest technologies and employ best practice approaches for flood investigations.

Key features of WMAwater’s floodplain management group:

  • completion of flood studies or modelling review work for over 65 different local Councils (and counting!);
  • depth of resources, with 17 professional engineering staff having recent experience undertaking flood studies under the NSW program;
  • a high degree of familiarity with requirements of key stakeholders such as state government departments and the State Emergency Services (SES);
  • a commitment to professional and industry development with primary authorship of over 36 papers on flooding and floodplain management, and a presence on key industry committees.

Specific Projects

  • Murrumbidgee River (Hay to Maude): The Hay to Maude study area encompasses 80 km of the lower Murrumbidgee River with the entire study area covering some 1,800 km2 . WMAwater were engaged to undertake a Floodplain Risk Management Study through two Phases, A and B. Phase A of the project comprised a Flood Study and data collection, which included a desktop environmental assessment. The key objective of Phase B was to develop community owned strategies for the management of the floodplain and its resources in the form of a Floodplain Risk Management Study and Plan.
  • Victoria Park: The Victoria Park Urban Renewal area is located at the site formerly occupied by Waterloo lagoon and swamp. The swamp was drained in the early 20th century and a racecourse was built, to be replaced after World War II by the Zetland Naval Stores depot, which occupied the site until the mid 1990s. Significant redevelopment of this area in the form of medium and high density housing as well as commercial premises has occurred in recent years, presenting many challenges in floodplain management.
  • Maitland Floodplain Management: The catastrophic 1955 flood at Maitland, which caused 14 deaths in the Maitland area, was a major catalyst for the development of modern floodplain management practices in New South Wales. The Lower Hunter River Flood Mitigation Scheme involves several kilometres of levees, floodways, and flood control structures. However, Maitland is still vulnerable to large floods, and floodplain management for the city is a primary ongoing concern.
