Geotextile groyne trial in battle to beat erosion

Noosa Council will install geotextile sand bag groynes along the Noosa River foreshore in a bid to curb erosion and restore the Munna Point beach.

Noosa Councillor Frank Pardon said tenders closed next week for the work, which includes the installation of three geo-fabric groynes and three geo-fabric ‘scour mattresses’ on the river bed.

“The groynes are designed to trap the sand on the foreshore to assist in rebuilding the profile of the beach,” he said.

Cr Pardon said Council had lodged applications with the state government to install the structures and commence a sand replenishment program.

“With the tenders closing next week we should be ready to go as soon as we get the green light,” he said.

“This is a trial project, similar to when we trialled the sand shifter to restore the dunes on Main Beach. That project proved very successful and we’ll be hoping for similar success with this work at Munna Point, but we are heading into the unknown,” Cr Pardon said.

Council installed temporary fencing along part of the shoreline late last year to improve safety while staff investigated a solution to the erosion, caused by severe weather.
