Question 1.
Define runoff.
Show hintHide hint
Think about what happens to rainwater after it hits the ground.
Question 2.
What does the SCS Curve Number range between?
Show hintHide hint
Consider the extremes of infiltration and runoff.
3Question 3.
What is runoff?
- Water that seeps into the ground
- Water that flows into water bodies after rainfall
- Water vapor released from trees
Show hintHide hint
Think about where rainwater goes after landing on the ground.
4Question 4.
True or False: The SCS Curve Number is only influenced by rainfall intensity.
- True
- False
Show hintHide hint
Remember the multiple factors that influence runoff.
Question 5.
Given a watershed with a Curve Number of 85, precipitation of 50 mm, and an initial abstraction of 10 mm, calculate the runoff using the SCS method.
Show hintHide hint
Remember to break the formula down step by step and calculate S first.
Question 6.
Analyze the effect of a steep slope versus a gentle slope on runoff behavior and hydrograph shape.
Show hintHide hint
Think about how the landscape influences the speed at which water travels.
