Summary
The site is located approximately 1.7 km upstream from the Eumundi-Kenilworth Road crossing. The downstream section of the site consists of a near-vertical bank, approximately 9 m in height. Each of the sections are approximately 120 m in length and are devoid of vegetation. The site abuts a floodplain that sits approximately 3 – 5 m above the inset floodplain immediately upstream of the site.
Streambank erosion at the site has resulted in a high, vertical and unstable bank at the downstream end and a high, steep/irregular bank upstream end. Channel widening and straightening processes have resulted in major sediment mobilisation (approximately 280,000 m^3 between 2013-2019) and over 130 m of bank retreat and subsequent loss of agricultural land. The current steep/vertical bank morphology will likely limit future vegetation establishment. In the absence of management interventions, ongoing erosion at the site may result in a range of impacts, including:
The recommended works for the Carter site include:
BenefitsThese works will provide immediate protection against erosion and help support the establishment of riparian vegetation.
