Coastal Monitoring

The City monitors the seasonal and long-term changes along our coastline, to better understand how we can manage and protect our coastal environment for the future.

How do we monitor?

  • Photographs captured twice a year at 51 beach sites.
  • Five beach monitoring cameras, capturing a photo every hour.
  • Land surveys of the City's coastline in April and October each year.
  • Aerial imagery of the coastline.
  • Wave date captured from three wave buoys moored off the City's coastline. This can be viewed by visiting: wawaves.org/wanneroo.
  • Water level and wind data supplied by the Department of Transport and the Bureau of Meteorology.

What did we find?

Between April 2022 and April 2023 major erosion was observed at Quinns Beach, Clayton’s Beach in Mindarie and north of Yanchep Lagoon Beach.    

While changes to the coastline are mostly seasonal, in recent years we have lost more sand to erosion than we have gained back in accretion. 

How do we help?

In September 2022 we placed sand at Yanchep Lagoon Beach in response to major erosion caused by winter storms. Beach renourishment was undertaken to improve beach usability and pedestrian access ready for the summer.       

Our Beach Renourishment Program ensures safer and improved beach access, while also protecting the dunes and coastal environment.

In April 2023 we undertook beach renourishment at two locations along Quinns Beach which created a buffer against winter storms.

Coastal Monitoring Report

Every six months a Coastal Monitoring Report is produced that outlines the methodology of the program and details any coastal changes that were observed over the last 12 months.
