The River Seph (or River Sep) is a tributary of the River Rye (itself a tributary of the River Derwent) in North Yorkshire, England.[1] The river flows for 13 miles (20.5 km) down Bilsdale and meets the Rye near the village of Hawnby.[2] When the surrounding land was owned by Roger de Mowbray, the river was referred to as the Sep.[3]
