Severn and Wye
Two of Britain's great western rivers. The Severn runs 220 miles from Plynlimon to the Bristol Channel; the Wye flows 155 miles through the Welsh borders to join the Severn estuary at Chepstow. Both face sustained pressure from agricultural runoff and sewage discharge, and the Wye in particular is the focus of major pollution litigation.
