Flood mapping system now online

Residents across the Bundaberg region can now access flood mapping relating to their individual properties based on upstream flood gauge levels.

RESIDENTS across the Bundaberg region, and especially those in floodplain locations, are now able to access flood mapping relating to their individual properties based on upstream flood gauge levels.

The online software that will allow residents to easily correlate flood gauge heights to potential inundation of their individual properties.

Following extensive flood modelling of the Lower Burnett River and community information sessions held in September, the council has now released the new state of the art interactive mapping system to the public.

The council's manager of design Dwayne Honor, said that after the 2010/11 floods, members of the public, landowners and council struggled to understand the relationship of key flood warning gauges on the Burnett River to potential flooding of properties downstream.

"Across the floodplain, people living adjacent the river wanted to know what a certain upstream flood gauge level at Paradise Dam, Walla or Bundaberg might mean to their individual properties," he said.

"Council is now able to provide interactive maps that highlight potential downstream inundation based on these flood gauge levels.

"The extent of mapping is from Paradise Dam to the river mouth at Bundaberg Port and covers some 275 square km of flood inundation area."

Mr Honor said that the new technology did not provide information regarding the flooding height on individual properties but did show where inundation was likely to occur.

"The information can provide property owners an understanding of what upstream gauge increments start to affect their properties and the potential flood extents that could be experienced," he said.

"It provides an interactive tool for people to understand potential flood impacts covering some 275 square kilometres of the Lower Burnett River"

Bundaberg Deputy Mayor David Batt said the new mapping interface was the culmination of extensive technical work with the program built and developed using the best available information including computer modelling.

"Councils project team was assisted by GHD flood engineers and spatial analysts from AAM Group," he said. 

"The maps will display across smart phones, tablets and PC's and is part of a mobile technology strategy that council has adopted.

"You can even use your devices GPS to zoom to your position on the map."

Cr Batt said the program was developed using funds contributed through the State Government's Flood Resilience Program.

The Bureau of Meteorology operate the Flood Warning System for the Burnett River and through their website, they provide the latest river heights at key gauge locations.

During flood events, the Bureau are able to predict some gauge levels including the Bundaberg flood gauge.

"The challenge has always been to define what those gauge readings mean in terms of potential flood inundation to private property downstream," Cr Batt said.  

"The new mapping system now provides a solution to these questions and is being provided in good faith and in the public interest."
