The course of a river is the direction in which a river flows. You must remember that all rivers flow downhill.

We can find 3 different courses in a river: upper, middle and lower course.




Upper course: usually, rivers are born in mountains. The place where the river begins is called the source. In the upper course, rivers flow very fast.

Middle course: as the rivers flows through flat lands, it gets slower. Thanks to tributary rivers, rivers collect more water and they get wider. Sometimes, rivers have bends called meanders.

Lower course: is where the river flows into the sea or the ocean. The place where the river joins the sea or the ocean is called the mouth.
