The top left photograph is looking downstream along the River Avon towards the confluence with the River Severn. Evidence of river bank stabilisation can be seen. The top right image is looking along the River Avon in Tewkesbury. Left - shows a weir on the River Severn at Tewkesbury to maintain water flow, to oxygenate the water and to prevent tidal saltwater entering the river system. Tewkesbury, because of its low-lying floodplain location and the confluence of two major rivers, has experienced serious flood events e.g. July 2007.
