the upper course, closest to the mountains and hills; the middle course, between the upper and lower courses; the lower course, the flattest area close to the sea.
It is a large bend , or part of a series of bends, in the lower course of a large river.
The upper course of a river is characterized by steep gradients, fast-flowing water, and features such as waterfalls and rapids, typically found in mountainous or hilly regions. In contrast, the lower course has a gentler gradient, slower-moving water, and broader floodplains, often exhibiting meanders and deltas as it approaches its mouth. The upper course primarily focuses on erosion and sediment transport, while the lower course is more about sediment deposition and shaping the landscape.
What features?
No, they tend to be found more in the Middle/Lower courses of a river. Where the process of smaller streams or rivers joining the main river is more common, than in the higher upper course.

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.
Wherever a river suddenly passes from a higher level to a much lower one. At the vertical, or near-vertical, edge of a hill or mountain.
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.
