The discharge of a stream is the volume of water that flows past a given point in a unit of time. Usually, we measure the world rivers by its discharge to the sea.
The water is not the only thing that moves in the stream. The sediment, sand, and gravel for example, “flow” too. This sediment transport has a profound effect on river dynamics.
Rivers are so diverse that there are incredible differences in the speed of the flowing, from almost stagnant lake stretches to wild rapids.
