3 cards from this section. Quick, good the night before a test.
Define Delta in the context of irrigation.
Think about the crops and their water needs.
What is Duty?
Consider the relationship to water discharge.
What is the relation between Duty (D) and Delta (Δ)?
Recall the derived equation!
True or False: Delta measures the total area supported by a flow of water.
Focus on what Delta represents.
An irrigation system has a Duty of 3000 hectares/cumec and operates for a base period of 90 days. Calculate the Delta for a given crop.
Focus on substituting the values into the derived formula.
Suppose you need to design an irrigation scheme for a series of crops with varying water needs. How would you prioritize the requirements based on Duty and Delta?
Consider each crop's specific delta values when allocating resources.
