The River Glaven in the eastern English county of Norfolk is 10.5 mi (16.9 km) long and flows through picturesque North Norfolk countryside to the North Sea. Rising from a tiny headwater in Bodham the river starts 2+1⁄2 miles before Selbrigg Pond where three small streams combine. The scenic value of the Glaven valley is important to the tourist industry in North Norfolk. The river is one of over 200 chalk rivers in the world and one of 160 in the UK.
