Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

You have a canal that irrigates 10,000 hectares with a discharge of 5 cumecs. Calculate the Duty and determine the required Delta for a base period of 150 days.

💡 Hint: Follow the formula for both Duty and Delta to solve.

Challenge 2 Hard

Evaluate how changing from a flood irrigation system to a drip system could improve Duty for a cotton crop.

💡 Hint: Consider the efficiency of different irrigation methods.
