Riverine flood maps show residents the effect of widespread and prolonged rainfall over a large catchment area. Riverine flood events may cause elevated water levels at our rivers and creeks for several days. Flash flooding can also occur following intense localised rainfall and with little warning.
These maps provide an estimate of how and where water will rise during a flood event. This information is important for emergency preparedness as it assists with disaster management and planning, for both council and our community.
Extreme event:
Low chance of occurrence, 0.05% annually, 3% in a 70 year period.
Examples (between major and extreme):
• Feb 1893 - All major river catchments (Riverine Flooding)
• March 2012 - Alexandra HeadlandKawana/Mooloolaba/Buddina/Warana/Alexandra Headland (Flash Flood)
• May 2015 - Beerwah/Glasshouse (Flash Flood)
Major event:
Medium chance of occurrence, 1% annually, 50% in a 70 year period.
Examples:
• Feb 2020 - Yaroomba/Mt Coolum/Marcoola (Flash Flood)
• Feb 1992 - Maroochy River (Riverine Flood)
• June 1983 - Nambour (Flash Flood)
• Mar 1955 - Kenilworth (Riverine Flood)
Moderate event:
High chance of occurrence, 10% annually, 99.9% in a 70 year period.
Examples:
• Jan 2012 - Nambour (Riverine Flood)
• Jan 2011 & Jan 2013 - Kenilworth (Riverine Flood)
Minor event:
Extreme chance of occurrence, 40% annually, 100% in a 70 year period.
Map published August 2021. Base terrain information is 2014/2018 aerial survey, enhanced with new Development DEMs where available.
This mapping presents surge heights above the Highest Astronomical Tide to show the effects of additional surge from the ocean during meteorological (storm) conditions. This information is important for emergency preparedness as it assists with disaster management and planning, for both council and the community.
Examples:
• Dec 2020 - All low lying coastal areas (0.3-0.4 m above HAT)
The maps were updated with new information in August 2021. |
