a river in Great Britain. The Severn is 310 km long (390 km with its estuary) and drains an area of 21,000 sq km. It originates on the eastern slopes of the Cambrian Mountains, flows primarily across a plain, and empties into Bristol Channel. It is fed chiefly by rain. High water is in the autumn and winter; in the summer the river becomes extremely shallow. The mean flow rate is approximately 250 cu m per sec. The Severn is navigable as far as the city of Stourport and is accessible to seagoing vessels in the lower course. It is connected by canals with the Thames, Trent, and Mersey rivers. A high bridge was built across the estuary in 1966, and there is a tunnel near Bristol. The cities of Shrewsbury, Worcester, and Gloucester are located on the Severn, and the cities of Newport and Cardiff are located on the estuary.
