The discharge of a river is the discharge that the river puts out into the sea. This is often the finer silt that the river has picked up and carried from the upper and lower reaches of the river.

When a stream's discharge increases, erosive energy increases.
When the discharge of a stream increases, so does it's velocity. When it decreases, so does the velocity.
the competence and capacity of a steam depend on a streams velocity and discharge. Because the velocity and discharge of a given stream are not constant , the competence and capacity of a stream are not constant . competence and capacity vary along a stream and change throughout the year.
The discharge for a single stream should not change much from the headwater to the mouth. The exceptions to the mouth would be if another stream joined the main stream, which would increase the discharge or if you loose a significant amount of water to infilitration, which would decrease the discharge. The gradient should be high at the headwaters and gradually decrease downstream where it should be low at the mouth. Of course differences in lithologies or secondary streams can change the gradient for a short distance, thought the overall profile should fit the expected model.
The total volume of flow in streams is termed discharge.

A heavy rainfall, or more water released from a reservoir.
