12. Depth-Area-Duration Relationships

Try these first

1. 1.

   What does DAD stand for?

   Hint

   What are the three components of the relationship?

2. 2.

   Explain why DAD curves are important?

   Hint

   Consider their application in water resource projects.

3. 3.

   What is the primary utility of DAD relationships?

   • Flood design
   • Only in urban areas
   • Not used anymore

   Hint

   Think about water management systems.

4. 4.

   True or False: DAD curves assume consistent rainfall behavior.

   • True
   • False

   Hint

   Consider climate change impacts on data.

5. 5.

   Given a DAD curve for a region, if the rainfall depth is 100 mm over 1 km², calculate the expected depth for a 5 km² area using the DAD formulae you know.

   Hint

   Remember how depth decreases as area increases.

6. 6.

   Analyze how climate change can potentially alter DAD relationships in coastal versus inland regions.

   Hint

   Consider the different impacts climate change might have.
