Detailed hydrologic analysis and hydraulic modelling has been undertaken to map the predicted flood extents, levels, depths, velocities and hazards associated with a range of possible flood types from a 1 in 5 year flood, up to a 1 in 500 year event and the PMF Event (Probable Maximum Flood). The study also considers the predicted effects of climate change on flood behaviour. The information collected from the community about their community’s experiences of flooding has been used to validate the flood model against actual observed flood events.
The draft Bonalbo Flood Study will be on public display until 4pm 23rd September 2021. It can be viewed at the following locations;
- Bonalbo post office
- Old Bonalbo post office
