The image above represents the net irrigation requirement. Two essential parameters are needed to calculate net irrigation requirements: Consumptive Irrigation Requirement (CIR) and Water Required for Leading and Other Purposes (Le).
The formula for calculating net irrigation requirement:
NIR = CIR + Le
Where:
NIR = Net Irrigation Requirement
CIR = Consumptive Irrigation Requirement
Le = Water required for Leading and Other Purposes
Let’s solve an example;
Find the net irrigation requirement when the consumptive irrigation requirement is 24 and the water required for leading and other purposes is 2.
This implies that;
CIR = Consumptive Irrigation Requirement = 24
Le = Water required for Leading and Other Purposes = 2
NIR = CIR + Le
So, NIR = 24 + 2
NIR = 26
Therefore, the net irrigation requirement is 26.
Calculating the Consumptive Irrigation Requirement when the Net Irrigation Requirement and the Water Required for Leading and Other Purposes are Given
CIR = NIR – Le
Where;
CIR = Consumptive Irrigation Requirement
NIR = Net Irrigation Requirement
Le = Water required for Leading and Other Purposes
Let’s solve an example;
Find the consumptive irrigation requirement when the net irrigation requirement is 32 and the water required for leading and other purposes is 8.
This implies that;

NIR = Net Irrigation Requirement = 32
Le = Water required for Leading and Other Purposes = 8
That is, CIR = NIR – Le
CIR = 32 – 8
CIR = 24
Therefore, the consumptive irrigation requirement is 24.

Calculating the Water Required for Leading and Other Purposes when the Net Irrigation Requirement and the Consumptive Irrigation Requirement are Given
Le = NIR – CIR
Where;
Le = Water required for Leading and Other Purposes
NIR = Net Irrigation Requirement
CIR = Consumptive Irrigation Requirement
Let’s solve an example;
Find the water required for leading and other purposes when the net irrigation requirement is 24 and the consumptive irrigation requirement is 12.
This implies that;
NIR = Net Irrigation Requirement = 24
CIR = Consumptive Irrigation Requirement = 12
That is, Le = NIR – CIR
Le = 24 – 12
Le = 12
Therefore, the water require for leading and other purposes is 12.
