Sluices in realignment schemes
| Guidance: The use of sluices allows the volume of tidal flooding
to be controlled. Particularly suited to sites that are currently too low
to support saltmarsh vegetation if opened to a natural flooding regime.
An aim of these techniques is to allow sediment on to the site to raise
ground levels so that when the embankments eventually fail saltmarsh will
be able to develop and the reduced tidal volume will have less of an impact
on the estuary. |
Comment: Used at some sites in Germany.
