Challenge Problems

Push your limits with challenges.

Question 1

Given a scenario with five rain gauge stations in a watershed with the following recorded rainfall amounts: Gauge A: 2.5 in, Gauge B: 3.1 in, Gauge C: 4.4 in, Gauge D: 3.6 in, Gauge E: 1.9 in. The area influenced by these gauges is 10 sq miles total. If Gauge A's polygon covers 3 sq miles, Gauge B covers 2 sq miles, Gauge C covers 1 sq mile, Gauge D covers 2.5 sq miles, and Gauge E covers 1.5 sq miles, calculate the mean precipitation.

💡 Hint: Ensure you calculate the weighted average correctly.

Question 2

Describe a case where using the Thiessen Polygon Method would yield significantly different results from the Arithmetic Mean Method. Why would this be the case?

💡 Hint: Focus on how the spatial configuration of rainfall affects outcomes.
