2024 Hawkesbury-Nepean River Flood Study

A flood study is a technical investigation of the way floods behave within a river catchment and underpins floodplain management. The aim of a flood study is to define existing flood behaviour, particularly the chance and severity of different sized floods happening. The 2024 Flood Study builds on the 2019 Regional Flood Study and includes 12 technical reports. The Study is available on the NSW Flood Data Portal.
