In more mathematical or scientific terms, it is a measure of the extent to which input is well used for an intended task or function (output).
for irrigation in general,
Different types of Irrigation Efficiencies,
- Water Conveyance Efficiency (ղc)
It includes losses which occurs in conveyance from point of diversion into canal system to the fields.
- Water Application Efficiency (ղa)
It includes losses such as runoff from the field and deep percolation.
- Water Use Efficiency (ղu)
It includes water required for leaching.
- Water Distribution Efficiency (ղd)
Where,
y = average numerical deviation in depth of water stored
d = average depth of water stored in the root zone during irrigation
Higher is the water distribution efficiency better is the crop response.
- Water Storage Efficiency (ղs)
Wn = F.C. - Available moisture in the soil prior to irrigation,
