Flood and Overland Flow
Flood represents the type of flooding that occurs when heavy rainfall causes the water levels in a river, creek or urban drainage system to rise and exceed the capacity of the main channel or pipe network.
Overland flow is excess rainfall runoff from homes, driveways and other surfaces. Overland flow can cause flooding in gullies and depressions located upstream of rivers and creeks and also in areas where the runoff exceeds the capacity of urban drainage systems. It is generally caused by short, intense bursts of rainfall that are typically less than an hour long. Any flooding will usually go down shortly after the rainfall has stopped.
High Likelihood Flood (5% AEP)
This is a reasonably large flood event that is very likely to occur during your lifetime. A flood of this size has a 1 in 20 chance (or 5% chance) of occurring in any given year and location.
Within the Moreton Bay Region, a flood event of this size occurred in the middle reaches of the Caboolture River and the upper reaches of Cabbage Tree Creek in May 2015.
Medium Likelihood Flood (1% AEP)
This is a large flood event that could possibly occur during your lifetime. A flood of this size has a 1 in 100 chance (or 1% chance) of occurring in any given year and location.
A flood event of this size has occurred in both January 2011 and May 2015 in parts of the Moreton Bay Region. In January 2011 the flooding occurred in the upper reaches of the North Pine River and the middles reaches of Burpengary and Cedar Creeks.
Whilst in May 2015, the flooding was in the middle reaches of Burpengary, Little Burpengary and Elimbah Creeks as well as in the lower reaches of Todds Gully.
Low Likelihood Flood (0.1% AEP)
This is a very large flood event that is rare to witness during a lifetime. A flood of this size has a 1 in 1000 chance (or 0.1% chance) of occurring in any given year and location.
Within the Moreton Bay Region, a flood event of this size occurred in Terrors Creek in January 2011 and in the middle reaches of King Johns and Saltwater Creeks in May 2015. Whilst rare, these exceptional events can and do occur.
Storm Tide
Storm tide inundation can occur when weather conditions produce a storm surge resulting in sea levels above the normal tide levels. Storm surges that coincide with high tide can result in significant inundation of low-lying coastal land.
High Likelihood Storm Tide (5% AEP)
A reasonably large storm tide event that is likely to occur during your lifetime. A storm tide of this size has a 1 in 20 chance (or 5% chance) of occurring in any given year.
Medium Likelihood Storm Tide (1% AEP)
A large storm tide event that could possibly occur during your lifetime. A storm tide of this size has a 1 in 100 chance (or 1% chance) of occurring in any given year.
Low Likelihood Storm Tide (0.1% AEP)
A very large storm tide event that is rare to witness during a lifetime. A storm tide of this size has a 1 in 1000 chance (or 0.1% chance) of occurring in any given year.
On 30 March 2017 Ex-Tropical Cyclone Debbie produced up to a one metre surge along parts of the Moreton Bay coastline. Had this storm surge coincided with high tide this would have resulted in storm tide levels approaching the 0.1% event.
In 1967 Tropical Cyclone Dinah resulted in storm tide inundation 1.5 meters deep in houses close to the shore at Sandgate and significant inundation elsewhere within the Moreton Bay region.
