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.

How does a rivers gradient affect its speed erosion capabilities?

The steeper a river's gradient, the faster and greater the erosive power is.


What factors affect a river's ability to erode and carry sediment?

Factors that affect a river's ability to erode and carry sediment include velocity of the water flow, volume of water, slope of the riverbed, geology of the surrounding area, and the presence of vegetation or obstructions along the river's path. High velocity and volume of water, steep slopes, soft rock formations, and minimal vegetation can increase erosion and sediment transport capacity.


What does a rivers power to erode depend on?

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.


How does a river's speed affect its erosive ability?

Along with friction, turbulence slows the stream's flow and may also erode the stream.


What three factors affect how much energy a river has to cause weathering erosion and deposition?

The steepness of the river's slope, the volume of water flowing in the river, and the type of rock or sediment being eroded are the three main factors that affect how much energy a river has to cause weathering, erosion, and deposition. The faster the flow, the more erosive the river can be.

How is a river delta formed?

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.


What is an old river?

An ' Old River' is a river with a low gradient and low erosive energy. Old rivers are characterized by flood plains.


What are the features of a river channel that has a steep gradient?

If a river channel has a steep gradient, the river flows faster and has more erosive energy.


What would a river be called if there is a uplift in land?

A river that has experienced uplift and therefore becomes erosive again is called a rejuvenated river.
