12.7. Depth-Area-Duration Analysis Procedure

Try these first

1. 1.

   What is the first step in the DAD analysis procedure?

   Hint

   Think about what you need before starting any analysis.

2. 2.

   What do isohyets represent?

   Hint

   Consider how we would show rainfall variations on a map.

3. 3.

   What is the purpose of Depth-Area-Duration Analysis?

   • To measure temperature
   • To estimate rainfall distribution
   • To evaluate soil quality

   Hint

   Look for the term 'distribution' in the purpose.

4. 4.

   True or False: Isohyets can be used to visualize rainfall distribution.

   • True
   • False

   Hint

   Think about how we can represent equal quantities on a map.

5. 5.

   Given a set of storm data, how would you use the isohyetal method to determine average rainfall over a specific area?

   Hint

   Remember to consider the area represented between each pair of isohyets.

6. 6.

   Discuss how DAD curves can be integrated into flood modeling software and the implications of these models on urban planning.

   Hint

   Consider how these curves help anticipate the worst-case rainfall scenarios.
