lower course
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.
middle course, upper course, lower course...

The upper course, the middle course and the lower course
The upper, lower and middle course.
Crest
the width of the lower course ir 3km and the width of the upper course is 5km.
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.

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.
look there are three courses in a river the upper course, the lower course and the middle course upper course is shallow and fast and as the river rogresses it gets less shallow and less fast
