Abstract:

Field and documentary studies, centred on Hill Pill (Avon), Magor Pill (Gwent), Cold Harbour Pill (Gwent), and Oldbury Pill (Avon), show that over the last four hundred years the seabanks defending the Levels have been shortened, mainly by moving outfall structures progressively seaward along the streams and rivers. The process, which is continuing, reduces maintenance costs and risks, and appears to have been driven by an accelerating relative rise in sea level since the seventeenth century. This is evinced by survival of increasingly large and elaborate outfall works and seabanks. Some early outfall structures, at Hill Pill and Magor Pill (Prat Reen), have partly survived later repositioning of the sea defences.
