11. Consistency of Rainfall Records

Try these first

1. 1.

   What is the purpose of consistent rainfall records?

   Hint

   Think about how inaccurate data could impact engineering projects.

2. 2.

   Name one factor that can cause inconsistencies in rainfall data.

   Hint

   Consider changes that could affect measurements.

3. 3.

   What does a straight line in a Double Mass Curve indicate?

   • Inconsistency in data
   • Consistency in data
   • Data is unreliable

   Hint

   Remember what the graph stands for.

4. 4.

   True or False: Urbanization can improve rainfall measurement accuracy.

   • True
   • False

   Hint

   Think about the impacts of building construction on rainfall measurement.

5. 5.

   A rain gauge at Station B shows a sudden drop in rainfall measurements after a nearby construction project began. Analyze how urbanization could have affected these results. What steps would you apply to assess and correct the inconsistency?

   Hint

   Think about the specific impacts construction projects have on the surrounding environment.

6. 6.

   Design a procedure for routinely checking rainfall data consistency at your institution. Include description of methods, frequency of checks, and how you would document findings.

   Hint

   Consider how you might also include supplemental data from other sources, such as satellite measurements.
