1. 1.

   What is one common error in rainfall data collection?

   Hint

   Think about how physical devices can fail.

2. 2.

   What does interpolation do?

   Hint

   It fills in the gaps.

3. 3.

   What is the purpose of Double Mass Curve Analysis?

   • To estimate missing rainfall data
   • To compare cumulative rainfall data over time
   • To calculate average rainfall

   Hint

   Think about how we track data fluctuations.

4. 4.

   True or False: Observer mistakes can lead to inaccurate rainfall measurements.

   • True
   • False

   Hint

   Consider the reliability of human data entry.

5. 5.

   Analyze a dataset of rainfall readings from three gauges over a month where two have consistent readings and one shows unusual levels. What process would you take to assess the validity?

   Hint

   Focus on assessing the unusual readings against what you know from neighboring stations.

6. 6.

   Design a quality assurance plan for rainfall data collection that addresses both instrumental and observer errors.

   Hint

   Consider what could prevent errors in both tools and techniques.
