Dunedin council considers reinstating groyne to mitigate erosion at city beach
Moves to reinstate a wooden groyne at Dunedin’s St Clair Beach are making waves.
The Dunedin City Council will discuss a proposal to reinstate the beach’s timber groyne, which had been used with varied success since 1902.
A groyne is a series of poles embedded in the sand and built out from the beach, which affects how the sand moves.
Retaining sand at the beach is becoming increasingly important as large waves have stripped sand and exposed man-made ‘sand sausages’ at the foot of dunes, which form part of the low-lying area’s coastal defences.
