The document describes the three stages of a river's course from its source to its mouth. In the upper course, the river is narrow and fast-flowing from its source. In the middle course, the river widens and slows with meanders and sometimes tributaries. In the lower course, the river empties into another river, lake, sea or ocean at its estuary and mouth.
