Challenge Problems

Push your limits with challenges.

Question 1

Given a catchment with 4 rain gauges spread across varied elevations, analyze the potential risks involved with applying the Theissen Polygon Method. Suggest alternative methods that may offer improved accuracy.

💡 Hint: Reflect on the influence of different terrains on rainfall.

Question 2

Consider a region where rain gauges are clustered in one area while other parts are unmonitored. Discuss the implications of this layout using the Theissen Method and present a better sampling strategy.

💡 Hint: Think about the layout similar to city planning where resources must be spread efficiently.
