12056: Demonstrating erosion control on susceptible soils in the East Kimberley
Erosion is a significant threat to land systems in the upper Ord catchment.
According to a study carried out by the Department of Water in 2006, 12 million tonnes of sediment are washed into Lake Argyle each year. This loss of soil impacts on the productivity of the land by reducing vegetation cover and allowing the spread of weeds.
This project will demonstrate gully erosion control by:
- Completing the installation of check banks across an actively eroding gully.
- Installing a new series of check banks on a second gully adjacent to the first.
- Utilising both gullies as an ongoing demonstration site for landholders to observe the benefits of remediation work over the longer-term.
The demonstration site had the first phase of check banks installed in 2007 to demonstrate erosion control techniques to landholder's. These banks have been maintained and still provide sedimentation data. Installing new banks downstream will complete the picture and demonstrate the longer term viability of gully remediation.
