The mouth of the River Tees is at the North Sea. The lower course of the River Tees goes through Redcar near Middlesbrough.
Yangzi River.
A river usually flows quickly in the upper course, as it is at a higher elevation - mountains streams, waterfalls, etc. In the lower course, it will slow down as the lower elevation means the slope is more horizontal. It is here that the river may start to meander across the valley floor, forming bends, oxbow lakes, and a flood plain.
The lower course flows through Egypt, into the Nile delta where it divides into two distributaries, the Damietta to the east and the Rosetta on the western part of the delta. It then flows into the Mediterranean Sea.
what is a river process ? A river process consists of three 1.erosion (in the upper course) 2.transportation(in the middle course) and 3.deposition (in the lower course).
A young river is very active. It is still at the upper course. It moves at a characteristic high speed that enhances its active down-cutting and under-cutting. Its competence is very high due to its speed. An old river on the other hand is characterised by its materials and also the topography of its course. The old river has lost its competence due to the gradient of its course. The speed is low compared to a young river.
Fairly slow
The upper, lower and middle course.
The lower course in the sense of rivers, means that it is now nearing the end of its journey, where all the sediment, and nutrients it has picked up in the 'upper' course is now settling out, and making rich deltas and embankments to grow crops or have farms on. So the lower course of the river is where it is very mellow, and barely moving. And the upper course of the river is where its very fast and turbulent.
that part of the mouth or lower course of a river in which the river's current meets the sea's tide.
