Floodplain environmental change during the Younger Dryas and Holocene in Northwest Europe: insights from the lower Kennet Valley, south central England.
Many lowland rivers across northwest Europe exhibit broadly similar behavioural responses to glacialinterglacial transitions and landscape development. Difficulties exist in assessing these, largely because the evidence from many rivers remains limited and fragmentary. Here we address this issue in...
