Estimating Stream Discharge

Working with a very simple stream

Next we will estimate the discharge of a simple stream where the velocity changes with depth, but stays constant from side to side. Below is a cross section of such a stream. There is a "wading rod" tool, which you can move back and forth. Attached to the rod is a velocity sensor (a propellor device), which you can move up and down. The velocity and depth sensor readings can be seen below to the left.

1. What is the velocity value at a sensor depth of 0.30 m at 6.2 m on the tape measure?	m/s
2. How does the velocity at 9.1 m on the tape (also at a sensor depth of 0.3) compare with that at 6.2 m and 0.30 sensor depth?	greater than less than same as
