Allansford Flood Investigation and SWMS 2025 (Allans25)

A flood study is a technical assessment that defines how water behaves across a catchment or floodplain during times of flood. They involve the use of hydrologic and hydraulic models to determine flood extent, depth, velocity, and other mapping outputs for a range of flood scenarios. Outputs of the Allansford Flood Investigation and SWMS 2025 flood study were provided to Department of Energy, Environment and Climate Action (DEECA) FloodZoom Team and are published here. See below for more information about this study, including the map product types and the modelled flood scenarios:
