11.5.1. Ratio Method (Simple Correction)

Try these first

1. 1.

   What does P_c represent in the Ratio Method?

   Hint

   Think about what the adjustment aims to achieve.

2. 2.

   What is a possible reason for inconsistent rainfall records?

   Hint

   Consider environmental changes.

3. 3.

   What does the Ratio Method aim to correct?

   • Temperature data
   • Rainfall data
   • Wind speed data

   Hint

   Focus on the type of data we discussed in the section.

4. 4.

   True or False: The Ratio Method requires data from multiple neighboring stations.

   • True
   • False

   Hint

   Think about what the Double Mass Curve requires.

5. 5.

   Suppose a rainfall gauge has an old slope of 2.5 and a new slope of 3.0. If the original rainfall reading for July is 150 mm, calculate the corrected value for that month.

   Hint

   Focus on using the right formula for adjustment.

6. 6.

   Consider a scenario where two neighboring stations show a consistent slope, but your station's slope changes dramatically after a decade. Discuss the implications for data reliability and how the Ratio Method could be applied.

   Hint

   Think of how neighboring data helps validate the station's records.
