Question 5: What impacts do dams have on the transportation of sediment? (Check all that apply).

A. Water upstream of the dam will increase in flow velocity and erode sediment.

B. Water upstream of the dam will decrease in flow velocity and deposit sediment.

C. Water immediately downstream of the dam will have a high sediment load and deposit sediment.

D. Water immediately downstream of the dam will be relatively free of sediment, and the river will erode its bed and banks to reestablish its missing sediment load.
