Challenge Problems
Push your limits with challenges.
Question 1
Given rainfall data from four gauges: 7 mm, 12 mm, 10 mm, and 20 mm. Using the Arithmetic Mean, calculate the areal rainfall. Then discuss how this method might not reflect true areal rainfall in an area with varying distributions.
💡 Hint: Consider if there are any gauges much higher or lower than others.
Question 2
You have rainfall data from five locations forming a Thiessen polygon. The gauges show 5 mm, 10 mm, 15 mm, 20 mm, and 25 mm. Discuss how you would apply these data using the Thiessen Polygon Method.
💡 Hint: Think about how you would determine which gauge influences which area.
