Look at the image above. At which location is the greatest amount of sediment most likely being deposited?
Explain why the water depth at point A is greater than the water depth at point C
Describe why the rate of erosion is always more dominant than the rate of deposition on the outside of a curve.
A decrease in the velocity of this stream will most likely cause an increase in
At which locations is erosion dominant over deposition?
The accompanying table above shows the rate of erosion and the rate of deposition at four stream locations. A state of dynamic equilibrium exists at location
Why does equlibrium exist at this location?
Would you expect the stream to be deeper at Point A or Point B? Explain
Which of the cross sections above represents the stream bottom from A to B?
Describe any conditions that might cause the rate of erosion in a stream to increase
The map above shows a meandering river. Points A and B are locations on the banks of the river. What are the dominant processes occurring at locations A and B?
