River channel adjustment to meander cutoffs on the River Bollin and River Dane, northwest England

Auteur(s) et Affiliation(s)



Description :
Morphological adjustment of a channel after cutoff should be expected. Four natural cutoffs which have occurred since 1980 on two rivers in northwest England have been monitored from pre-cutoff stage. Two of the cutoffs were neck cutoffs of large loops, two were chute cuoffs in which significant bend curvature remained. All were the terminal result of progressive bank erosion and/or scour of the floodplain rather than overflow and all took place in peak flow events. rates of change in all morphological, sedimentary and biotic componentsexhibit an exponential decline with time but with slightly differing timescales.
