Holloways and Clifton Beaches in Cairns have faced ongoing erosion for decades, threatening public infrastructure, parklands, and essential roads. ICM provided innovative erosion management solutions that maintained beach access and public use along the foreshore.
Project details
Client: Cairns Regional Council
Date: 2024
Location: Clifton Beach & Holloways Beach, Cairns, Far North Queensland
About this project:
The Challenge:
Holloways and Clifton Beaches experienced severe erosion, leading to the loss of vegetation and the risk of damage to critical public assets. Traditional erosion control methods posed challenges in balancing cost, environmental impact, and public accessibility.
The Solution:
ICM conducted a detailed design process to identify the most effective erosion management solution. Through options assessment and cost-benefit analysis, a nearshore breakwater design was selected. This approach combined nature-based principles with low-impact, cost-efficient engineering.
The design process included:
Use of the GenCADE sediment transport model to assess beach stabilisation and impacts.
Evaluation of multiple structure types, including groynes, breakwaters, and artificial reefs, using diverse materials such as geotextile structures and pre-cast concrete.
Calibration based on similar structures at Ellis Beach to optimise performance and recreational outcomes.
ICM also prepared detailed technical specifications, safety plans, and an Adaptive Management Plan to address future coastal risks and monitoring requirements.
