Sand trapping protects erosion hot-spot

Tuesday February 5, 2013 - 13:22 EDT

Coffs Coast beaches escaped the worst of the recent wild weather with erosion hot spots hit less hard than feared.

The Coastal Communities Protection Alliance says it was worried about how beaches at Wooli would cope with strong winds.

The beach only lost about ten centimetres of sand.

Alliance president Bruce Bird said sand trapping at Wooli helped protect the dunes.

"The sand trapping fences haven't lost anything, there was one, maybe two that had a small scouring out between them," he said.

"What they do, they trap the sand as the wind blows along and helps it to build up.

"That is what the ocean would normally work on before it would work on eroding away the dune."

Mr Bird said the Wooli beach only lost about ten centimetres of sand, but the sand trapping that protects local dunes will not work everywhere.

"Each beach is unique in its design and the way it faces onto the ocean and how that reacts also with the ocean currents," he said.

"They are all different I don't think there is only one method that you could say would be the panacea for all."
