THE Yamba breakwall copped the full force of this week's storm, but may also have a role to play in the erosion at Whiting Beach.
It's clear from the tidal debris and spread of sand that the waves from Wednesday's storm were big enough to climb over the break wall, which the Department of Primary Industry maintains via Crown Lands.
A spokesman said there had been no reports of damage to the structure, but it would undergo an inspection as the department assessed all of its infrastructure assets along the coast in the wake of the storm.
But the breakwalls could also be indirectly responsible for the erosion at Whiting and Turners beaches by reflecting the wave energy from the southern swell into the beaches (see diagram).
Council was trying to secure funding to engage experts to explore wave dynamics, deputy GM Rob Donges said.
