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.
