Brief description

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.

This dataset includes outputs from state-of-the-art hydrologic and hydraulic modelling, offering detailed flood information on peak levels, depths, velocities, extents, and hazard classifications for events ranging from frequent floods to the probable maximum flood (PMF).
