A river's velocity is hugely important as erosion on the outside of a meander is solely down to this factor. This is because the river is hurling rocks (abrasion) and air bubbles into the rock face, causing it to break down quickly. The quicker the river, the more abrasion and hydraulic action will cause erosion. This means that the meander moves outwards, and causes further erosion.
The steeper a river's gradient, the faster and greater the erosive power is.
Increases it
A river's power to erode depends on the gradient, the volume and velocity, and the quantity of erosive burden. A river will normally move outwards on bends, deepening the farthest channel, and thus increasing the erosion on that bank.
Along with friction, turbulence slows the stream's flow and may also erode the stream.
An old river is a river with a low gradient and low erosive energy. Old rivers are characterized by flood plains.
the river flows faster and has more erosive energy
it would not be a river it would be stream
The factors that affect a river's ability to erode and carry sediment would be its size, how deep it is, and how fast it is going. If it is going downhill that can also affect it.
A river delta is formed from the deposition of sediments carried by a river as the river enters an ocean, sea, lake, or another river. This is because the flow velocity decreases significantly and the fluid loses the ability to transport sediment.
An ' Old River' is a river with a low gradient and low erosive energy. Old rivers are characterized by flood plains.
A river that has experienced uplift and therefore becomes erosive again is called a rejuvenated river.
If a river channel has a steep gradient, the river flows faster and has more erosive energy.
