Video Script:
The River Tees is a major river in the north east of England. It rises at Cross Fell in the Pennines and runs for 137 km to its mouth with the North Sea near Middlesbrough.
The upper course of the river is made of a hard rock called whinstone, which has resulted in the formation of a V-shaped valley and interlocking spurs. The UK’s largest waterfall can be found in the upper course: it has formed where a layer of whinstone is above a layer of sandstone and shale. The latter rocks are softer and as a result the waterfall has formed, where the river drops 21m. Cow Green Reservoir is also found in the upper course which stores water for urban areas if they run out of water in the summer. Much of the land around the river is used for grazing animals.
In the middle course, lateral erosion takes over and meanders are formed.
These grow larger in the lower course, also forming oxbow lakes. Levees have also formed due to past flooding events and the floodplain is very flat and wide. Use of the river becomes industrial in the lower course which can be seen where the river has been straightened near Stockton. At the river mouth there is a large estuary with mudflats and sand banks, which make up a nature reserve.
