Title: Lower Colne improvement scheme : environmental costs and benefits
Author: A. Driver
Document Type: Monograph
The Lower Colne improvement scheme, on a river system to the west of London, was the first in the Thames region to give equal importance to environmental and engineering aspects in a feasibility study which was carried out in the early 1980s. This resulted in a scheme proposal comprising sixty elements of discrete work, rather than a continuous new channel or embankments, which reduced the impact on the environment. Many of these separate elements comprise environmental mitigation and enhancement features. This paper focuses on (a) examples of different types of scheme, (b) the environmental advantages and disadvantages, and (c) the costs of incorporating such features into flood-defence works.
