| Abstract |
In England, many estuaries have been effectively canalised, or so constrained that natural energy attenuation provided by saltmarsh and mudflat has been severely impaired. In this paper, it is argued that there is a need for a change in the management of estuary form, flood defence design and the maintenance of other coastal structures that influence morphological evolution. This needs a radical departure from popular thinking that existing structures should be maintained in situ. Such an approach, whilst defying the popular view of flood and coastal management, is likely to lead to sustainable form, and lower maintenance and capital investment costs in the long-term. In many cases, positive measures to widen the mouth of many estuaries will be needed and reversal of canalisation should be an objective where saltmarsh extent is too limited for effective sustainable flood management. |
