When the discharge of a stream increases, what happens to stream speed?
What will be an ideal response?
Answer: An increase in discharge will always mean that a larger volume of water is being transported by the stream. But an increase in discharge does not always mean that stream speed will increase. Increases in discharge and speed do not always have a direct correlation because changes in channel geometry and the cross-sectional area of the channel might also occur.
