Walk along the Avon at low tide and you cannot fail to miss the glistening layers of silt that line its banks.
The Bristol Channel has the second largest tidal range in the world, and with that comes enormous movements of silt.
These movements have blocked rivers and contributed to flooding, lain on banks and been used in industry, been dug from ditches and spread over fields, and, recently, provided inspiration for historians and artists.
This talk explores how people across the Severn Estuary have lived with silt, slime and sand over the last five hundred years, and provides historical background on plans for their future management.
Speaker: Dr John Morgan is Lecturer in Early Modern History at the University of Manchester.
This is a UWE Regional History Centre talk.
