A line of small waterfalls and rapids on the rivers?

Explanation:
The fall line is a line along many rivers where the water drops from higher land to lower land, creating a series of small waterfalls and rapids. In Virginia, the Fall Line marks the boundary between the Piedmont and the Coastal Plain and helped towns grow there because water power could be used for mills. A delta forms at a river’s mouth where sediment builds up; an estuary is where freshwater mixes with seawater at the river’s mouth; a tributary is a smaller river that flows into a larger one. Therefore, the line of small waterfalls and rapids on rivers is the fall line.
