If an irrigation system has a duty of 12 hectares/cumec and a base period of 20 days, calculate the required Delta. How might this information influence planning for the agricultural season?
💡 Hint: Use the formula for Delta to find the answer.
Assuming a duty reduction to 6 hectares/cumec while the base period remains at 25 days, what will be the new Delta needed? Discuss the potential consequences on crop yield.
💡 Hint: Consider what happens to the irrigation needs when Duty is altered significantly.
