Practice Questions

Test your understanding with targeted questions related to the topic.

Question 1

Easy

What happens to rainfall depth as the area increases for a fixed duration?

💡 Hint: Think about how rain spreads over a larger surface.

Question 2

Easy

What does the term 'saturation point' refer to?

💡 Hint: Consider when soil becomes unable to absorb more water.

Question 1

What happens to rainfall depth as the area increases?

  • Increases
  • Decreases
  • Remains Constant

💡 Hint: Remember the rule of spreading rainfall over larger surfaces.

Question 2

True or False: DAD curves become steeper with increased duration.

  • True
  • False

💡 Hint: Consider the overall trend with data points.

Challenge Problems

Push your limits with challenges.

Question 1

You have a DAD curve that shows a rainfall depth of 80 mm for a 10 km² area over 12 hours. How would this change if the area is expanded to 50 km²? Calculate the expected average rainfall depth if the trend holds.

💡 Hint: Use the trend observation that deeper analysis suggests lower average depth as area increases.

Question 2

Consider a design storm requiring an analysis of two DAD curves—one representing a local storm and another a regional storm. Discuss how each curve's characteristics would affect design considerations for flooding.

💡 Hint: Focus on how depth-area relationships dictate spatial planning.
