stream erosion and deposition

Front

What is stream erosion?

Back

Stream erosion is the process by which flowing water removes soil and rock from the stream bed and banks, leading to the shaping of the landscape.

Front

What is stream deposition?

Back

Stream deposition is the process by which sediment carried by a stream is dropped or settled when the water slows down, leading to the accumulation of materials in certain areas.

Front

What factors influence stream velocity?

Back

Stream velocity is influenced by factors such as slope (gradient), channel shape, roughness of the stream bed, and the volume of water flow.

Front

How does slope affect stream speed?

Back

The steeper the slope, the faster the stream flows due to the increased gravitational force acting on the water.

Front

What happens to sediment as water velocity decreases?

Back

As water velocity decreases, larger and heavier particles are deposited first, followed by smaller particles.

Front

Where are the deepest parts of a stream typically found?

Back

The deepest parts of a stream are typically found near the outer bends of meanders and in areas where the water flows fastest.

Front

What is the relationship between stream velocity and sediment transport?

Back

Higher stream velocities can transport larger and heavier sediments, while lower velocities result in the deposition of smaller particles.

Front

What is the significance of points B and C in a stream?

Back

Points B and C are typically locations where the greatest stream velocities are found, often due to the channel's shape and slope.

Front

How does the shape of a stream channel affect erosion and deposition?

Back

The shape of a stream channel can affect how water flows, influencing areas of erosion (where water is faster) and deposition (where water slows down).

Front

What is the impact of vegetation on stream erosion?

Back

Vegetation can reduce stream erosion by stabilizing soil with roots, absorbing water, and slowing down water flow.
