              Severe flood events in small settlements downstream caused this to be considered. The Environment Agency were the main driver behind this measure being implemented, looking for lower-cost solutions to enable protection of small communities where high capital expenditure could not be justified.  Other 'normal'flood defence approaches failed cost benefit criteria for support, and would not be suitable within Belford due to shortage of space between the channel and nearby houses. The 'natural' approaches were financially viable for the site, and enabled storing and attenuating flows in the upstream area.
