Challenge Problems
Push your limits with advanced challenges
If an irrigation canal has a discharge of 15 cumecs and irrigates a total of 37,500 hectares, calculate the Duty. If the base period is 150 days, find the Delta.
💡 Hint: Break the problem into two parts: first calculate Duty, then use that to find Delta.
An irrigation project requires that 1000 hectares needs a total of 80 cm of water over 120 days. What should be the capacity (in cumecs) of the irrigation system?
💡 Hint: Convert water depth to meters and apply the Delta formula in reverse.
