Remember them?
When they were newsworthy I read many posts on media sites from ordinary people saying that rivers should be cleared, dredged, cleaned up and allowed to flow. Nobody claimed that the methods were a cure, but that they would help the situation for virtually nothing compared with hemming the rivers in with walls and levees and moving the problem to somewhere else.
The government and Environment Agency were adamant, though: build, spend £hundreds of millions every year, put cities on stilts...... The thinking appears to be that things have to be visible for miles so that claims of being seen to be doing something can be made.
Turn to the Chartered Institution of Water and Environmental Management (CIWEM) - people who might know something about water flows - and they are with the ordinary people. They are talking of returning to the work of the now defunct Regional Water Authorities and the National River Authority to create upland floods, to stop the water from getting to the middle and lower levels, and of keeping the other levels clear to allow them to flow. More power to them, they want to work with nature rather than hem it in.
As a young lad I used to do a lot of walking in the Pennines and the Dales and there were times when areas in the woods and moors were nothing but bogs, but they served a purpose. A simple sluice, not much more than board in a break in the bank, would allow water to drain into a clean ditch. The ditch would eventually split into more ditches and they would get shallower and until they eventually disappeared. I can also remember teams thinning out reed beds in the slower reaches of the river Aire to keep it flowing.
