9. Twineham Restoration

Themes: Fisheries; Natural rivers


  • 19. The effects, on fish and fisheries, of restoring rivers to a more natural state will be clearly identified and taken into account in river restoration plans.

Project description


An in-channel restoration project to provide habitat for invertebrates and fish at all life stages.


A series of berms were constructed through the upstream section of the river Adur at Twineham to provide multiple benefits to the river and recreational users. Built on alternate sides of the channel, the berms have created sinuosity, flow diversity and a slight increase in the water level, providing additional stability to the banks.  In addition, five backwater refuge habitats were created by fixing erosion control matting onto the newly excavated areas and re-seeding them with a restoration mix.
