where does the river teme start and end
River Teme The River Teme (pronounced /tiːm/; Welsh: Afon Tefeidiad) rises in Mid Wales, south of Newtown, and flows through Knighton where it crosses the border into England down to Ludlow in Shropshire, then to the north of Tenbury Wells on the Shropshire/Worcestershire border there, on its way to join the River Severn south of Worcester. The whole of the River Teme was designated as an SSSI, by English Nature, in 1996.
Tiber The river rises at Mount Fumaiolo in central Italy and flows in a generally southerly direction past Perugia and Rome to meet the sea at Ostia. Popularly called flavus ("the blond"), in reference to the yellowish colour of its water, the Tiber has heavily advanced at the mouth by about 3 kilometres (2 miles) since Roman times, leaving the ancient port of Ostia Antica 6 kilometres (4 miles) inland.[4][5] However, it does not form a proportional delta, owing to a strong north-flowing sea current close to the shore, to the steep shelving of the coast, and to slow tectonic subsidence.
