Challenge Problems
Push your limits with advanced challenges
A botanical garden measures its CWR at 180 mm. Effective Rainfall is 60 mm, Groundwater contribution is 30 mm, and soil water available is 20 mm. Calculate the IR required and discuss how varying conditions might affect this requirement.
💡 Hint: Use the IR equation methodically.
Analyze how an anticipated drought might change irrigation practices based on the IR equation. If CWR is fixed, what adjustments would farmers need to make in their water sourcing?
💡 Hint: Think about water conservation strategies and management plans.
