12.8. Use in Estimating Probable Maximum Precipitation (PMP)

Try these first

1. 1.

   What does PMP stand for?

   Hint

   Think about extreme weather conditions.

2. 2.

   Why are DAD curves important?

   Hint

   Consider their role in hydrological analysis.

3. 3.

   What is the purpose of using DAD curves in regards to PMP?

   • To minimize flood design costs
   • To understand precipitation variations
   • To analyze historical rainfall patterns

   Hint

   Think about what DAD curves represent.

4. 4.

   True or False: PMP is the maximum possible rainfall that can occur in a specific area during extreme weather.

   • True
   • False

   Hint

   Recall the definition of PMP.

5. 5.

   Given a historical storm with a maximum rainfall of 200mm and spatial distribution data, predict the PMP for a region with 50km² area using DAD curves.

   Hint

   Look at maximum rainfall allowed by DAD curves for similar areas.

6. 6.

   Discuss how changes in climate might affect the estimation of PMP and the considerations engineers must take.

   Hint

   Think about how historical patterns could shift.
