Question 1.
What is interception?
Show hintHide hint
Think about how rainwater interacts with trees.
Question 2.
How does interception affect surface runoff?
Show hintHide hint
Consider the impact of rain on a forested area.
3Question 3.
What is the main effect of interception on surface runoff?
- It increases runoff
- It decreases runoff
- It has no effect
Show hintHide hint
Think about how captured precipitation behaves.
4Question 4.
True or False: Interception does not influence groundwater levels.
- True
- False
Show hintHide hint
Remember the flow of water through different layers.
Question 5.
Analyze a watershed region where interception accounts for a significant percentage of annual precipitation. How would this affect flood control measures?
Show hintHide hint
Consider how different types of vegetation can change the dynamics of water flow.
Question 6.
Calculate the expected runoff for a region with known interception values. Given 100mm of rainfall, if interception loss is 20%, what is the expected runoff?
Show hintHide hint
Use the formula: Runoff = Rainfall - (Rainfall x Interception Percentage).
