Challenge Problems
Push your limits with advanced challenges
A region has been urbanized significantly, and data shows that the rainfall variability is now 0.5. If planners originally wanted a density of 1 gauge per 500 km², how should they adjust their gauge placement?
💡 Hint: Make sure to recalculate the density based on the new coefficient of variation.
In a flat region of 1000 km², how many rain gauges would be necessary according to WMO guidelines? How does that change if you consider urbanization?
💡 Hint: Calculate the number of gauges based on the area and the guideline provided.
