Challenge Problems
Push your limits with challenges.
Question 1
A researcher has three stations with normal rainfall figures of 400mm, 500mm, and 300mm. Their recorded rainfalls are 50mm, 70mm, and 60mm respectively. If the normal rainfall at a missing station is 600mm, what should the estimated rainfall be?
💡 Hint: Don’t forget the formula as you calculate for each station!
Question 2
In a dataset, two out of five stations report problems with their gauges. Known normal rainfalls are 100mm, 150mm, and 200mm with recorded values of 10mm, 20mm, and 25mm. How would you apply the Normal Ratio Method to estimate the missing data assuming normal rainfall for the network is around 300mm?
💡 Hint: Remember to focus on how each gauge points its contribution.
