Norfolk: Spotlight on Natural Flood Management

Work is underway on the first of five natural flood management schemes along rivers in Norfolk to help manage flood risk to local properties and improve habitats, the Environment Agency said in its latest post. 

Natural flood management helps store flood water upstream and slows the flow of water along river channels, complementing the use of more traditional hard engineering downstream such as flood walls and embankments.

The first two schemes under construction in Norfolk are on Camping Beck in the Bure Catchment at Buxton, and the River Yare at Marlingford.

The Buxton project is being carried out through a partnership between the Norfolk Rivers Internal Drainage Board, the Broadland Catchment Partnership and the Environment Agency.

This work will involve storing flood flows upstream of Buxton village in an area that will enhance the environment through providing habitat, whilst helping to reduce flood risk downstream.

The Marlingford scheme is being carried out by a partnership involving Natural England, the Broadland Catchment Partnership and Environment Agency.

A series of ‘flow deflectors’ and lengths of woody debris will be constructed in the channel of the River Yare to redirect flood water on to the flood plain, so it is stored upstream for longer and reduces the risk to communities downstream.

Sections of the riverbank will also be lowered at strategic locations for the same reason, and ‘scrapes’ will be dug in to the floodplain to increase water storage capacity.
