But those rivers are not controlled by weirs so dredging will increase the flow, add any restriction like a bridge or weir and that is the primary issue not the depth of the river.Sorry, but even the EA have acknowledged that dredging helps:
Dredging underway on Steeping River, Lincolnshire
From the press release:
The Environment Agency and its partners agree there is no single solution that can eliminate flood risk. But that it can be reduced using a combination of methods.
Such a combination, including dredging, is proposed in wide-ranging plans to reduce the risk of a repeat of last year’s flooding.
The EA also got their wrists slapped for not maintaining the ditches on the Somerset levels, when they had flooding. For years after you could not view the levels without seeing a goodly herd of JCB's clearing the streams and ditches. One senior EA bod even got fired (memory fails who it was)
Yet dredging would not work on the Thames?
I say again. for those that did not read all my previous post; I acknowledge that the shoal in the thread title is not in EA waters.
