A river's "Capacity"

The amount of sediments a river can transport downstream is called its "capacity". Capacity is measured in cubic feet per second. The Mississippi River normally carries 50,000 cubic feet per second. A cubic foot is about the size of a small carry-on suitcase. Imagine 50,000 suitcases going by per second!

At flood stage the Mississippi River carries 200,000 cubic feet per second.

Capacity is related to the discharge, or the volume of water which flows past a point in a certain amount of time. Normally a stream such as the Mississippi carries enormous quantities of the small particles; clay, silt, and sand. A fast mountain stream can move large boulders, but usually only a few at a time.
