Hi. I am looking at putting leaky dams in a lowland stream running through arable land. High flows are rare but have occurred and been damaging downstream. The land is in HLS so has nice wide field margins. The landowner is however not keen because of potential damage to crops – so – I need to be able to demonstrate previous similar projects which have not damaged crops – can anyone provide me with evidence? Also, I was thinking of adding something which is a cross between a leaky dam and a check dam as I think any action is better than nothing and I’m trying to reach a compromise – so the dam would be raised above base flow but not come to the height of the bank and have a central low point to direct flow, basically just a board to slow flow – I cant find any examples of where this may have been done – opinions please.
