Project summary

Edit project overview to modify the project summary.


The Welland for People and Wildlife is a partnership project that will use CRF funds to restore 1.8km of the River Welland and its tributary the River Jordan, as they run through Market Harborough, Leicestershire. This project exists to turn the eyesore the River Welland has become into a central cultural feature, improving biodiversity, water quality and Water Framework Directive status. The Welland for People and Wildlife project strives to restore the River Welland through Market Harborough to a more natural form correcting the unsympathetic flood alleviation works which were carried out in the 1970s. This project aims to remove barriers to fish migration and improve community value without compromising flood defence.

The outcomes of the project are: 1.The return to near natural flow regimes of riffles and pools alternating in a new low flow channel. 2.Habitat restoration via the return of a natural mosaic of biotopes in riffles, pools, runs and bars 3.Biodiversity via the increase in species as a result of improved habitat diversity 4.Social and cultural benefits by recreating a recreational and educational environment for the people of the town 5.Water quality, as the biotope diversity will increase the ecological processes of the river, such as nutrient uptake 6.Ecosystem services (as a consequence of all the above)

Reasons for river restoration

Mitigation of a pressure Urbanisation
Hydromorphology Quantity & dynamics of flow
Biology Fish, Macrophytes, Macroalgae
Physico-chemical Nutrient concentrations
Other reasons for the project


Measures

Structural measures
Bank/bed modifications Pool creation; berm creation from pool arising; gravel placement for riffles; creation of low flow channel; opening of cut-off meanders; marginal planting
Floodplain / River corridor Removal of weirs and creation of a new 2-stage channel, with correctly-sized meander spacing and habitat mosaics (riffle, pool, runs, bars) in the low flow channel
Planform / Channel pattern Meander pattern created by modifying low flow channel bed with berm building
Other
Non-structural measures
Management interventions Planting wildflower mixes
Social measures (incl. engagement) Community Events; River open days; River Walks; Bioblitz event; Education events; School Tours
Other Community involvement before and during the project will ensure that the citizens are aware of the river, enhanced by information boards along the Riverside walk and the involvement of local schools and societies.
