Velocity Through Hole:
volume
area
time
velocity

Discussion Questions:

1. What two factors affect stream flow?

2. Is the velocity through the hole greater or lesser than the stream bed?

3. What was the gradient or % slope for each of the tests?

4. If this were a real stream, how could you prove that the volume was lessduring the one hole trials?
