Question

describe the processes by which sediments are moved by streams and the flow velocities that are necessary to erode them from the stream bed and keep them suspended in the water

Answer 1

Answer:

a) process

• saltation,
• rolling and traction
• suspension.

b) High flow velocities

Explanation:

The process by which sediments are moved by streams are

• saltation,
• rolling and traction
• suspension.

The flow velocities that can erode sediments from the bed  and keep them suspended in water have to be extremely high to be able to carry the sediments after agitating them from the River Bed. and this is dependent on the volume and capacity of the water body
