Description :
In the lower reaches of the Calder (Lancashire) tributary of the Ribble catchment (northwest England), 5 river terraces set into the surrounding glacial terrain have been mapped and their underlying sediments radiocarbon dated. Evidence for late Pleistocene and Holocene fluvial environments is presented. The record of Holocene alluvial activity is compared with geomorphological research undertaken in the adjacent uplands of the Bowland and Howgill Fells and the more extensive database of change in river systems draining eastwards from the Pennines. Base-level changes may have been a fairly significant factor affecting the lower Calder during late glacial and early Holocene times. Late Holocene vegetation changes, particularly woodland removal, driven by anthropogenic land-pressure appear to have rendered the floodplain prone to channel migration and the landscape more susceptible to erosion.
