Coastal Adaptation Projects Currently Underway

Sunset Beach Geotextile Sand Container Groynes

Three additional Geotextile Sand Container (GSC) groynes and sand nourishment along Sunset Beach to mitigate coastal erosion began on 7 March 2023.  More here

The 40m long low-crest GSC groynes, spaced 70m apart, will be constructed south of the existing groyne and revetment built in 2019.

Approximately 7,000m3 of sand will be imported to nourish the foreshore area. The sand will provide an initial nourishment to the foreshore south of the groyne and allow the littoral drift process to feed the beach to the north of the northern groyne.  Littoral drift is the process by which sand is moved along the coastline by wave action. For Western Australia, this process moves sand along the coast in a northly direction.

The $1.5 million project is joint funded with $750,000 provided by the State Government through the CoastWA Hotspot Coastal Adaptation and Protection (H-CAP) Major Project Fund.

Construction of the groynes will be undertaken by a local contractor with coastal engineers M P Rogers providing technical services.

The estimated date of completion is May 2023.
