Detailed explanation-1: -Gradients are typically the lowest at a river’s mouth, and highest at its headwaters. The higher the gradient, the faster the stream flows. Channel shape and texture. The shape and roughness of the channel also affect the velocity of the flowing water.

Detailed explanation-2: -Water and sediment move more rapidly through streams with a steep gradient, while streams that are more gradual in slope may have slow moving water that allows sediment to settle to the bottom.

Detailed explanation-3: -On the outside of a curve, the water flows faster than the inside of the curve. The water erodes some of the river bank and carries the sediment downstream. However, on the inside of a curve, the water flows more slowly. This slower speed causes the water to drop sediment that it may have been carrying.

Detailed explanation-4: -The energy of flowing river water comes from the force of gravity, which pulls the water downward. The steeper the slope of a river, the faster the river moves and the more energy it has. The movement of water in a river is called a current. The current is usually strongest near the river’s source.

Detailed explanation-5: -A waterfall is a river or other body of water’s steep fall over a rocky ledge into a plunge pool below. Waterfalls are also called cascades.
