6 sample questions

Question 1.
Define effective rainfall.
Show hintHide hint
Think about what happens to rainfall before it contributes to runoff.
Question 2.
What factors are excluded when calculating effective rainfall?
Show hintHide hint
Consider the processes that consume rainfall before it contributes to runoff.
3Question 3.
What is effective rainfall?
- Rainfall that accounts for all precipitation
- Rainfall that leads to surface runoff
- Rainfall that is intercepted by vegetation
Show hintHide hint
Remember, it's what flows directly to water bodies.
4Question 4.
True or False: Effective rainfall includes losses due to interception.
- True
- False
Show hintHide hint
Clarify what loss factors are considered and ideally excluded.
Question 5.
A rainfall event in a catchment results in 100 mm of total rainfall. If 20 mm is intercepted by vegetation and 30 mm infiltrates into the ground, calculate the effective rainfall.
Show hintHide hint
Remember the formula E = R - I - P.
Question 6.
Discuss how changes in land cover (like deforestation) might affect effective rainfall in a watershed. Consider impacts like runoff and soil moisture.
Show hintHide hint
Think about how vegetation affects rainfall absorption and runoff rates.
