The Hawkesbury-Nepean River Flood Study (May 2024) provides high-resolution spatial and temporal data identifying areas in the Hawkesbury-Nepean Valley affected by flooding, including backwater inundation of tributaries, and assesses the potential impacts of climate change on flood behaviour. The study covers the 21,400km² catchment and the 190km river length from Bents Basin near Wallacia to Brooklyn, encompassing Local Government Areas such as Penrith, Hawkesbury, Blacktown, The Hills, Wollondilly, Liverpool, Hornsby, and Central Coast. The TUFLOW model input files provide the most up-to-date and reliable flood information for the Hawkesbury-Nepean River and should be used to inform all flood-related decision making from June 2024.
