How will channel velocity change along the longitudinal profile of a stream?
A) Velocity will remain constant for the entire length of the stream
B) Velocity will start high and gradually decrease toward the mouth due to increasing discharge downstream
C) Velocity will start low and gradually increase toward the mouth due to increasing discharge downstream
Question 2
What is the longitudinal profile?

B) The cross-sectional area from the headwaters to the mouth
C) The slope of the stream channel from headwaters to the mouth
D) The probability of a specific stream discharge occurring in a given year
