The River Thames is the most important river in southern England, originated in the Cotswolds Mountains, flowing through Oxford, London and other cities into the North Sea, a total length of 346 km. The river is unfrozen throughout the year, the water level is relatively stable, and the tide of the seagoing sea can lead to London.
