Monitoring our coastline

CoastSnap_800x500px.png

Our region’s coastline extends from Point Plomer in the north, to Diamond Head in the south. 

Our coastlines are constantly evolving. Storms and stronger tides move sand offshore, which typically returns during calmer conditions. 

We regularly conducts water quality tests for our key estuaries and rivers and to track what changes are occurring and the health of the systems. Water quality monitoring is conducted at Lake Cathie, Duchess Creek, Saltwater Creek and Rainbow Beach, and the results are published weekly.

To track long-term movement patterns, we operate a citizen science project with CoastSnap.

How CoastSnap works

CoastSnap relies on repeat photos at the same location to track how the coast is changing over time due to processes such as storms, rising sea levels, human activities and other factors.

This is a low-cost method for mapping shoreline change using smartphone images collected by the community and uploaded to social media platforms. The data collected helps us understand and forecast how coastlines might change in the coming decades, so we can best plan coastal management practices that will future-proof our stunning coastlines.
