As a stream's carrying capacity decreases, which of the following sizes of sediments will be deposited last?
width, depth, and velocity all increase
As the discharge of a stream increases, which of the following also happens?
increases
Consider the equation Q = wdv. According to the equation, if Q (discharge) remains constant, but w and d decrease (as when a channel becomes more narrow and shallow), the velocity will
True
Stream width, depth, and velocity are all responsive to discharge rates.
fluvial
Stream-related processes are termed

False
Rivers make excellent political boundaries since they are clearly defined landform features.
