McAuley Westmead students at Collaroy beach
Year 10 Geography students studied beach erosion and management strategies at Collaroy beach last week.

Year 10 Geography students have been studying environmental change and management and as part of their study they visited Collaroy and Narrabeen beaches last Wednesday.

The students have written a report below:

“The 2016 storm that hit Collaroy caused much beach erosion and impacted housing near the beach. Our excursion looked at the management strategies implemented to improve this erosion. One strategy that was very eye-catching was the sea walls that were built to stop the beach from eroding further, in particular the vertical concrete seawall which was established to make the water splash up and away, preventing the housing near the beach from being impacted again by severe waves.

The excursion gave us an insight into how changes over time have helped shape Narrabeen and Collaroy beaches. A big thank you to Mark, Ashley, Sam and Lydia, who led us on the day, and a massive shout out to our teachers for taking us on this excursion”

“I was fascinated to learn about the complex dynamics of coastal erosion and its impact on urban development. Exploring the beach, we discovered how natural forces such as tides, wind and waves shape the coastline on a continuous basis, presenting both opportunities and challenges to coastal communities. Witnessing firsthand the erosion vulnerability of buildings and infrastructure highlighted the importance of taking proactive risk-mitigation measures. I learned about strategies like sand replenishment, seawalls, and dune management, all of which play important roles in protecting our coastal environments.

Furthermore, learning about the Coastal Erosion Emergency Action Sub-Plan demonstrated the importance of being prepared when dealing with erosion events. This experience not only expanded my understanding of coastal processes, but it also emphasised the importance of long-term coastal management approaches to protect both communities and ecosystems. I'm so grateful for this experience and the opportunity to know more about our Australian beaches”
