Project summary

Edit project overview to modify the project summary.

Alkborough Flats are on the south bank of the Humber Estuary, on the eastern side of the confluence between the River Trent and the River Humber. The site is around 440 hectares of agricultural land, of which approximately 375 hectares are protected by a flood embankment constructed in the late 1950s. The Alkborough tidal defence scheme increases the level of flood protection to an area stretching from the Humber Bridge to Goole up the tidal River Ouse and as far as Keadby Bridge on the tidal River Trent. The scheme features include a 20 metre-wide breach of the existing flood bank, a 1,500 metre length of lowered embankment or spillway and a new section of floodbank to protect assets at the edge of the site. The scheme has been designed to: reduce the impact of sea level rise; safeguard the internationally important nature conservation interest of the Humber by creating new wetland habitat; provide a focus for education and access opportunities for local communities.
