At the headwaters (in the mountains) the gradient is steep, then as the stream moves into the foothills and onto the plains on its way to the sea where it has its mouth, the gradient gets less and less steep.
Q-Tips
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 gradient typically decreases as you move from the headwaters to the mouth of a stream. This is because the elevation drops and the slope becomes gentler downstream.

Water erosion, mostly by streams and rivers that have a high gradient and discharge.
the Mississippi headwaters is a kind of thing that is located in the Mississippi river. The Headwaters of a river are it's origins. The multiplicity of small streams that converge to form the main body of the river proper.

High gradient streams have steeper slopes, which means they have more energy and power to transport larger sediment particles. The fast flowing water in high gradient streams can effectively carry and move these large particles due to the force of the water flow.
The ability of a stream to erode and transport material largely depends on its velocity, gradient, and discharge. Streams with higher velocities, steeper gradients, and greater discharge have more erosive power and are better able to transport sediment.
Headwaters are the beginning part of a river where it originates, often located in higher elevations as small streams or springs. Floodplains are flat areas around a river that flood during periods of high water, serving as natural reservoirs for excess water and supporting diverse ecosystems.
Bedrock channels are more likely to be found near the head of a stream where the gradient is steeper and erosion processes are more active. As the stream flows downstream and the gradient decreases, the likelihood of encountering bedrock channels decreases as well.
