Question 1.
What is the formula to derive DDF curves?
Show hintHide hint
Think about the basic relationship between rainfall depth, intensity, and duration.
Question 2.
Why is it important to derive DDF curves from IDF curves?
Show hintHide hint
Consider which data is critical for water balance studies.
3Question 3.
What is the primary formula to derive DDF curves?
- Intensity ÷ Duration
- Depth = Intensity × Duration
- Depth ÷ Intensity
Show hintHide hint
Think about how each component interacts.
4Question 4.
True or False: DDF curves can represent only rainfall intensity.
- True
- False
Show hintHide hint
Consider what DDF stands for.
Question 5.
A storm produces an intensity of 75 mm/hr for 45 minutes. Calculate the rainfall depth and contextualize how this depth could affect local waterways.
Show hintHide hint
Convert minutes to hours before performing the multiplication.
Question 6.
Consider a catchment area that receives an IDF indicating an average intensity of 50 mm/hr for a storm lasting 2 hours. How does this example illustrate the use of DDF curves?
Show hintHide hint
Again, remember that depth is key in DDF applications.
