Coastal Processes
Erosion along the coastlines of Australia and the world, is a significant natural process that shapes the planet's diverse coastal landscapes.
The combination of powerful waves, tides, and weather patterns can lead to the gradual wearing away of cliffs, dunes, and beaches. Coastal erosion in Victoria is influenced by various factors, including sea level rise, storm events, and human activities such as coastal development and sand mining.
This erosion can have both positive and negative impacts on the coastline. While it contributes to the formation of picturesque features like sea caves and sandy beaches, it can also pose risks to infrastructure, ecosystems, and communities.
Understanding the processes and patterns of erosion in Victoria is crucial for effective coastal management and the preservation of these valuable natural resources. Ongoing research, monitoring, and strategic planning are essential to mitigate the potential hazards associated with coastal erosion and ensure the long-term sustainability of Victoria's coastlines.
Several sections of the beach that the Whitecliffs Foreshore Reserve Committee of Management manages are under significant pressure from these coastal processes and this has impacted amenity at these beaches, with some sections of beach impassable at high tide.
We are working with DEECA to address the issues. There are several assets around Blairgowrie, including the seawall east of BYS, included in the recent Port Phillip Bay Coastal Processes Study commissioned by DEECA to identify high-risk assets and coastal infrastructure. We are waiting on the release of these recommendations to DEECA; and subsequently, their advice for further options that could benefit both the sections of coastline we manage and have broader benefits.
