Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Given five rain gauge stations located at these coordinates: (0,0), (4,0), (0,3), (4,3), and (2,1.5), construct the Theissen polygons and determine their areas.

💡 Hint: Start by plotting on graph paper for a clearer view.

Challenge 2 Hard

A catchment area has three rain gauges with areas A1=6 km² (P1=80mm), A2=4 km² (P2=120mm), and A3=2 km² (P3=200mm). Calculate the weighted average rainfall.

💡 Hint: Break down the computation step by step to avoid mistakes.
