The Severn estuary has the second highest tidal rise and fall in the world. Five major rivers flow into this estuary and sundry smaller rivers. The major rivers are the Severn (UK’s longest river at 220 miles), Wye, Usk, Parrett and Avon.

It is one of the most designated estuaries because of the significance of its wetland habitats and wildlife.
So its designations include all of the following:
