Pegging diversion banks

 

This video shows how to peg a diversion bank using a level and staff so that the machinery operator builds a bank at a suitable angle to the contour and doesn't exacerbate the problem. It follows on from video 5 - "gully erosion", but does not suggest that when you see a gully you should run out, peg and put in a diversion bank. You should do a lot of background work first.

For example, look at the whole property to understand how much erosion you have and where it will cause you the biggest problem or loss of assets. Then you need to get technical advice about how you address priority areas, such as where natural ground level needs to be restored, where steep sided banks need to be battered, where diversion banks or check banks need to be put in, the topography and amount of water each bank is expected to intercept, what direction water should be spilled, the dimensions and spacing of the banks to deal with the amount of water coming at it....excetera.
