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?

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
