Sunset Beach Coastal Adaptation Works

The Sunset Beach Foreshore has been experiencing ongoing coastal erosion which has recently lead to the removal of City assets to prevent them from falling into the ocean.

The City engaged M P Rogers & Associates to investigate and provide advice on potential coastal adaptation options for Sunset Beach which include groynes and revetments.

In late 2019, construction of a low-crest Geotextile Sand Container (GSC) groyne and revetment on the Sunset Beach Foreshore at Triton Place to mitigate coastal erosion was completed. Read more here

The 40m low-crest GSC groyne and 50m long GSC revetment being constructed at Triton Place will help retain an initial beach nourishment. 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 $418,000 project was funded by the City of Greater Geraldton’s CHRMAP Adaptation Measures Budget.

Construction of the groynes was undertaken by Natural Area Consulting Management Services with M P Rogers providing technical services.
