A review of the current key proposals as originally promoted by the Severn Tidal Power Group and the alternatives, with emphasis on the potential hydro-environmental impact of a barrage, including implications for geomorphological and flood risk changes. An outline will follow of recent research undertaken by the Hydro-environmental Research Centre on bacterial-sediment interactions and the application of computational hydro-environmental models to predict the impact of a Severn Barrage
on tidal currents, sediment transport concentrations, and bacterial and water quality levels.
