What affects stream erosion?
There are three factors that affect stream erosion. These are water velocity, shape, size and depth of channel, and stream capacity to transport eroded materials.
How does water create stream valley?
The Velocity
How would a reduction in friction in a stream channel affect the streams velocity?
As water in the stream channel flows, it encounters friction; the friction slows the forward movement. The shape,size, and roughness affect the amount of friction. High friction slows the stream significantly.
How does a stream's gradient affect its velocity?
the difference in velocity is mostly due to the great efficiency of the large downstream channel.
How does an increase in a streams velocity affect its discharge and carrying capacity?
When the discharge of a stream increases, so does it's velocity. When it decreases, so does the velocity.
How does a river's velocity affect its competence and capacity?
the competence and capacity of a steam depend on a streams velocity and discharge. Because the velocity and discharge of a given stream are not constant , the competence and capacity of a stream are not constant . competence and capacity vary along a stream and change throughout the year.
What is the difference between stream discharge and stream velocity?
Stream discharge is a product of the velocity and the area of the stream (velocity x width x depth), and has units of volume per time (e.g. cubic feet per second, cubic meter per day, etc). Stream velocity is the vector describing the speed of the water and has units of length per time (feet per second, meter per second). Stream discharge is relatively constant as you move up and down a stream, while velocity will change predominately as you change depth. The velocity of water is lowest near the bed of the stream, and highest at the surface.
Why one stream could be flowing faster than the other stream?
The velocity of the water in a stream increases when the stream gets narrower or shallower (or both).
How does a stream carry materials?
Stream load is when solid matter is carried by a stream. Stream capacity depends on the velocity, the amount of water flow and the grade.
What happens after a stream discharge increases?
After a stream's discharge increases, it overflows its banks and a flood occurs.
Stream gradient role on stream velocity?
An increase in gradient will generally increase stream velocity.
Where is deposition dominant in a stream?
On the inner curve of a meander, where the velocity of the water is the slowest.
