    I just think there will always be a limit to how much water you can shift in a certain amount of time, if you try to contain it it will always find a way out.
    Contain it in a river, pipe, waterway etc,.and it will just rise, higher and higher, it actually needs a large area where it can spread out, but these areas dont have that, other than the towns, its running off the hills at a fast pace.
    Its flash flooding really, due to massive amounts of rain.

      Most of the aircraft specification glass panels fitted, Pete, are 1.8 metres in height [5ft 11 inches] so you weren't far out. I suppose the answer to your question:

      is higher:dunno: It's also well known that over the last decade rivers etc have not been maintained or dredged as often, as thoroughly, or even dredged at all due to cut backs in spending as happened in the Somerset floods. Places of high risk such as Cumbria and the surrounding area should be prioritised for maintenance and regular dredging but instead have been subject to cuts despite the Governments assertions that it is spending more now. Also another rule introduced by Defra 3 years ago is not helping in deciding if the money is spent on rural high risk areas.


      "Under the new rules brought in three years ago, the Department for Environment Food And Rural Affairs (Defra) wanted to see an average of £8 of damage avoided for every £1 they would spend on schemes.

      Previously, projects were simply expected to deliver more than £1 of damage avoided for every £1 spent, with an average across all schemes of £5 of damage avoided for every £1 spent.

      The more stringent targets were introduced after the coalition started to slash the Environment Agency's funding for flood defences, with central government expenditure cut from around £670m when the government came to power in 2010 to about £576m for the next three years."

        The way those rivers were running I would say they were being dredged by nature.

        Surely dredging is not the answer, lower rainfall is.


        And we cant control that one.:smile:

        I'm sure Bangladesh will be setting up fund to help out.:biggrin:

        Well, I think if you read SteveR's post in this thread, Pete, you'll find that the people who live locally and suffer the consequences of repeated flooding will possibly disagree with you.:dunno:

        As for the second..............that ain't going to happen. We are having, it appears, warmer Winters. Warmer air carries more moisture and during Autumn and Winter that must be even more so.:hate-shocked: Whether or not the heavy rainfalls are due to Climate Change is another subject. But, as a Fisherman, I have seen how not dredging and no maintenance of the rivers is slowing the flow of water. I fish on the Rivers Ouse, Nene, Welland, and a few others where now, due to lack of maintenance, they are choked from bank to bank with thick weed. That slows the water down acting as an obstruction and any heavy rainfall means they are more prone to breaching the banks because the water can't flow any faster. Dredging deepens the channels and gets rid of silt, sludge and any debris that hinders the flow of water.....it's a necessary thing.:coffee:

          The river I was watching was flowing as fast as it possibly could, when a river takes out a bridge its usually getting a lick on.

          I just think in these days we look for someone to blame, if you want to blame anyone, try God.

          Believe it or not, and I know its hard to understand, but there are some things that humans just cant control, if they manage to do it short term, that is the best we can hope for.

          You can call it climate change or whatever, but we wont win in the long term.

            @pete, you're right, we won't win in the long term, as long as we keep insisting that nature plays by our rules instead of us playing by nature's rules.

            We have vast areas of wasteland, deliberately managed as wasteland, burning vegetation andpreventing trees from growing (much of the moorland ). We stick impermeable concrete, tarmac and such everywhere, build towns in flood plains, and then ignore all natural and man made drainage systems because maintenance costs money.

            When I say 'we' do all these things, I really mean government, national park authorities, certain land owners etc, ie the ruling class, leaving the ordinary folk to suffer the consequences.

            It's a shame really. We all know it's going to rain. We know we'll get storms. We know we can manage the country in a way that mitigates against such events, yet those with the power and authority to make it happen choose to ignore it. It's like when Devon flooded. The farmers got blamed for cutting down the trees, even though it was the government that just a few years earlier, told them to cut the trees down to make the land more productive.

              Well, it would do, Pete, as it was probably 4 times the volume it should have been but it was also probably 3 times as deep than normal due, partly, to being restricted over time by lack of maintenance. It's the same as pipes getting restricted by "furring up" only in rivers the water has only one option.....to go up and outwards. Dredging and regular maintenance of rivers, etc, is not the complete answer but it goes a long way to deal with heavy rainfall.

              Oh, stop picking on Big "G":doh:, the poor fella is always being picked on and being blamed for anything that goes:dunno:.


              It's not so hard to understand, Pete, and I agree with you completely. But that surely doesn't mean we should shrug our shoulders fatalistically and not do anything. Probably that is what the Government would like to do as it saves them money:heehee:

              Again, I agree with you, Pete. The Politicians of each country have their own nationalistic agendas and getting them to agree to anything practical and effective is nigh on impossible despite all the hand shaking, big friendly smiles, and waving of bits of paper, that mean absolutely nothing. for the TV cameras..

              The rivers through Keswick, down to Cockermouth and on to Workington mostly run shallow on bedrock covered by rocks and pebbles, no significant dredging can be done here in my opinion, the rivers surrounding valleys are now a moving sea, they are a natural flood plain anyway.

              The flood defences worked, but where just not high enough I can remember the outcry at the proposed height during the planning stages until today, and they would not have been as high unless the people of Cockermouth and surrounding area had not fund-raised towards it. An extra couple of foot would probably do it and it could be mostly out of sight until needed by being of the float up type, so when the water gets to a certain level, it pushes the defences higher, but mostly...you never see it

              I also don't buy into the now quoted drivel that defences stopped 6ft of water invading Cockermouth, whether it is 1ft or 12ft of water running through the town, its a flood and requires the same clean up time, money and distress from property owners and causes the same damage overall.

              Steve...:)

                That was Keswick.

                They do need to build it higher but they also need to set aside areas as proper flood plains. To do that properly would require the will and the money and the engineering ability.

                  It kind of looked a bit silly anyway, bearing in mind this flood ripped up roads and bridges.

                  A concrete wall would be better, but would it be acceptable?

                  I can only guess the glass was there in an effort not to make the defences look awful and still allow a view of the river in more normal times.

                  There are things you could possibly do, but would they fit in with the area?
                  I presume the locals wouldn't want the place to look like a concrete jungle.

                  Mr Cameran's government slid £116,000,000 out of the flood defence budget, probably to pay for his plane upgrades

                  Is the flooding receding there now and is the situation improving at all @Steve R ?
