Description
Description River Stour Flood Plain is important for palaeohydrological studies of the River Severn, providing both morphological and sedimentary evidence relating to the development of the river during the late Devensian. The site includes the Power House Terrace and the lower flood plain. It is of particular value in that it relates closely to geomorphological conditions before and after a critical date of 15,000 years BP. In addition to information on sedimentary environments, the deposits have provided valuable information on episodes of channel infilling and accumulation rates.
