Australian coastal observation network

Australia’s coastline is one of the country’s greatest natural, economic and cultural resources. The asset value of existing beach-front infrastructure is immeasurable. Climate change is driving sea level rise and changing regional wave climates, resulting in coastal erosion and increasing threats to coastal sustainability.

This research project launches a strategic international collaboration between university, industry, and government to address the considerable and growing pressure for solutions to observe and forecast accelerating shoreline erosion. The initiative is a proactive response to the October 2009 House of Representatives Standing Committee on Climate Change Report: Managing our Coastal Zone in a Changing Climate, that identified the urgent need to better understand the risks of coastal erosion through monitoring and modelling.

The study addresses the knowledge gap between advancing Climate Change science, and the lagging development of our ability to quantify, assess and forecast coastal variability and change.

The three-year project is establishing and rigorously testing a practical approach for establishing baseline coastal monitoring at 10 beaches along the NSW open coastline (Lennox Head, Sawtell, Dixon Park - Newcastle, Wamberal, Terrigal, Collaroy-Narrabeen, Manly, Wanda Beach - Cronulla, Thirroul and Shoalhaven) to build an empirical shoreline model that will enable prediction of wave and sea level impacts on beaches anywhere in the world.

Australian Coastal Observation NetworkComplementary to existing water-level and ocean wave monitoring programs that already exist around much of the Australian continent, the purpose of this present effort is to initiate and demonstrate the practical capability and value of sustained, automated and ongoing coastline monitoring (via surf camera technology) in support of coastal management, engineering and research.

Intensive RTK-GPS beach surveying, LiDAR, bathymetric surveying and inshore wave monitoring using aircraft, jetskis, quadbikes, cameras and buoys, are underway to rigorously test the applicability of existing and new coastal camera infrastructure to routinely obtain automated measurements of local wave climate and shoreline variability.

Of particular importance, is the application of this new data to underpin new developments in forecasting seasonal to multi-decadal shoreline variability and change.
