Palaeoenvironmental Investigations of the River Chelmer, Chelmsford, Essex, UK

The value of understanding the landscape context within which sites of human occupation are situated is key to understanding their function and locality. The recovery of a borehole adjacent to the current course of the river Chelmer during the replacement of the existing A138 Chelmer Viaduct and river bridge allowed the palaeoenvironmental analysis and radiocarbon dating of floodplain sediments. The results of which demonstrated that woodland clearance and possible exploitation of the valley floor were occurring by early Bronze Age, despite a lack of archaeological evidence for settlement at this time. The nearby sites of Springfield Lyons and Great Baddow demonstrate a lack of human activity in this period although unexcavated cropmark evidence from within the wider valley may yet demonstrate the presence of earlier human activity. This study demonstrates the potential of the Chelmer valley to preserve palaeoenvironmental records and potentially for the preservation of archaeological sites in the floodplain deposits.
