Bank errosion on a small stream, any ideas on how too stop it ??
I have a small stream about 3ft wide, that dries up in mid summer, but
can be a raging torrent in winter up to 2ft deep. The bank sides are approx 40 deg sloping, and made of builders rubble and soil. The stream bed looks like it just builders rubble. Over the years the banks have started to be undercut with the water, and then the bank gives way. So the stream is getting wider and the banks are getting steeper. Access is very limited and there is no chance of getting any machinery in, except hand tools. Any ideas on the best way, and cheapest of trying to stop this errosion. |

I'd have a peek upstream to see what other people have done too - if it's got worse (and just to be nosey) -- http://www.freedeliveryuk.co.uk http://www.holidayunder100.co.uk |

It "might" be the Water Authority's responsibility to do something about it. Have you checked? If it is, you get it done for free. |

If you intend doing any work on a watercourse you need to involve - and probably get permission from - the Environment Agency. As they're dealing with this type of problem all the time they would anyway be a useful source of advice and expertise. Flood Defence is probably a good department to start off with. |

I am not sure about Flood defence in this case ! If you contact the E.A. they will tell you if the stream is registered with them. We had a problem with our stream and the E.A. could only advise - not physically help as it is not "one of theirs". If the "unregistered" stream is on the boundary between two landowners then it is up to the "riparian " owners to sort it between themselves. Regards Pete www.thecanalshop.com |

Your right on that, as its in a new housing estate. Whereby both banks
come with the property. Ones of the problems is that the stream was diverted, so they could built moew houses. But my bets are the stream is trying to get back to its original course. It looks like as the most cost effective option is to use wooden stakes every 750mm and then board up at he back, and rock infill behind it and the bank. I am told that heavy vaccum tanalised timbers will last over 10 years.

I am told that heavy vaccum tanalised timbers will last over 10 years. I would use the pointed angle iron fencing posts, backed by good chain link fencing, then back filled with rocks. For this, you might find a demolition taking place where large manageable chucks of concrete could be obtained. They would last longer with regards to erosion and the limited power even a torrent would have in trying to dislodge them. Wooden stakes and boarding will as you realise rot and then the backfill would be exposed and again washed away Just a few thoughts. Water is funny stuff AND powerful |

The message
from dutchman contains these words: Your right on that, as its in a new housing estate. Whereby both banks come with the property.

Planting willows would be cheaper and better - and if you plant the right ones (osiers) you can harvest them and flog them to basket-makers... -- Rusty Direct reply to: horrid dot squeak snailything zetnet point co period uk Separator in search of a sig |
