Erosion in the Kyeamba Valley has been a significant issue for many years, with most landholders dealing with headcut formation and migration, channel incision and gully or tributary erosion at multiple sites across their properties. In order to manage the erosion, and reduce its ongoing progression across valuable farmland, landholders have used a range of costly engineering solutions, most with limited success. Farmers were keen to repair the damage, but needed a new solution.
With the assistance of a qualified consultant, we were able to provide landholders with tailored solutions for their erosion issues using a variety of low-cost erosion control techniques. The structures used for headcut stabilisation included brush ramps, log steps, rock rundowns, tyre mattresses and poplar headcut armouring. We also introduced various grade control structures, including brush mattressing, brush weirs and one rock dams.
Landholders were given practical demonstrations in the construction of each type of structure through a series of field days, while a Case Study Booklet produced through the project documented the various structures and provided examples of where they had been utilised on local properties.
