The document summarizes the work of the Severn Estuary Levels Research Committee from 1991-2005. The committee was made up of amateurs and professionals from universities, local authorities, heritage organizations, and archaeological contractors. Their goals were to coordinate, promote, and disseminate research on the archaeology of the Severn Estuary region, and to provide an academic overview of archaeological and environmental research. Over the years, they produced annual reports, conferences, publications, and field meetings to share knowledge about sites dating back 10,000 years that have been uncovered throughout the estuary.
