Answer: Therefore, the rivers speed is at its maximum at the headwaters (high gradient, high energy) and at its minimum at the base level (no gradient, lowest energy). An incoming tide can reverse a river and cause it to flow against the gradient -- uphill! Erosion and speed have a direct relationship. As speed increases erosion increases as well.

Explanation:

The velocity of a river increases if the gradient increased.

What is Velocity?

Velocity may be defined as the rate of change of distance of a body with respect to time.

It is known that, if the gradient increases, the velocity of a river increases or the speed of the stream flows becomes faster. This is because the gradient is directly proportional to the velocity of an object.

Therefore, the velocity of a river increases if the gradient increases.
