2 cards from this section. Quick, good the night before a test.
What does Delta (Δ) represent in irrigation?
Think about how much water a plant needs from seeding to harvest.
What is Duty (D) in relation to irrigation?
Consider how we measure water efficiency for irrigation.
What does Delta (Δ) measure in irrigation?
Focus on what crops need for their growth.
True or False: Duty (D) is the volume of water supplied to crops.
Think about how water is applied to areas.
An irrigation system has a discharge of 15 cumecs and can irrigate 30,000 hectares. Determine the Duty and subsequently calculate the Delta for a base period of 150 days.
First, find Duty, then apply it to calculate Delta.
Analyze how the type of crop and irrigation method can affect the Duty requirement for a given amount of water usage.
Compare traditional irrigation methods with modern techniques.
