We were thrilled with the success of our Low Cost Erosion Control workshop held on Saturday 27th February.
The workshop was facilitated by Cam Wilson from Earth Integral and hosted at the property of Peter & Kate Heeley, “Sunnyside” between Berridale & Dalgety. Thanks so much to Cam and Peter & Kate for making it such a great day. See below for photos of the day.
After some initial presentations from Cam about the factors causing erosion and some potential solutions, the group built 2 structures on small gullies nearby. In the first case a single layer rock “rundown” was built at the head of a small erosion gully. This structure protects the eroding headcut, captures sediment, encourages infiltration and assists vegetation to establish.
The second gully saw a brush weir built. Here logs are secured to the gully floor, and branches secured to the logs. Once again this slows channel flow, captures sediment, encourages infiltration and assists vegetation to establish.
Both structures used low cost materials available from close to the work sites. They are very suitable for small to medium sized erosion issues, and can easily be installed with relatively inexperienced labour. All participants enjoyed the day and found it very productive.
We are hoping to run another of these field days later in the year so look out for it in our email newsletters.
