Irrigation efficiency definition

Irrigation efficiency. (IE) means the measurement of the amount of water beneficially used divided by the amount of water applied. Irrigation efficiency is derived from measurements and estimates of irrigation system characteristics and management practices. The irrigation efficiency for purposes of this ordinance are 0.75 for overhead spray devices and 0.81 for drip systems.

Irrigation efficiency. (IE) means the measurement of the amount of water beneficially used divided by the amount of water applied. Irrigation efficiency is derived from measurements and estimates of irrigation system characteristics and management practices. The minimum average irrigation efficiency for purposes of this ordinance is 0.71. Greater irrigation efficiency can be expected from well designed and maintained systems.

Irrigation efficiency or “IE” means the measurement of the amount of water beneficially used divided by the amount of water applied to a landscape area. Irrigation efficiency is derived from measurements and estimates of irrigation system characteristics and management practices. The minimum average irrigation efficiency for purposes of these Guidelines is 0.71. Greater irrigation efficiency can be expected from well designed and maintained systems. The following irrigation efficiency may be obtained for the listed irrigation heads with an IME of 90%:

Examples of Irrigation efficiency in a sentence

• Irrigation efficiency is derived from measurements and estimates of irrigation system characteristics and management practices.

• Irrigation efficiency improvements usually result in reductions in return flows and increases in consumption (negative "real" water savings).

• Irrigation efficiency decreases the deep percolation of water into fields and therefore the amount of selenium in the drainage water.

• Irrigation efficiency improvements can be broken into on-farm and district-wide efforts.

• The following equation was used to determine the unit irrigation demand for Method B: [(ET0 x Tc x Qf) – (P-R)] ÷ eiWhere:ET0 = Monthly evapotranspiration, from Texas ET Network (inches) Tc = Turf coefficient (unitless)Qf = Quality factor (unitless)P = Average monthly precipitation, from TWDB (inches) R = Runoff, 25% of precipitation (inches)ei = Irrigation efficiency, (assumed 75%)The irrigation demand was calculated using the area of each parcel to be irrigated as provided by the city Parks Department.

Irrigation efficiency means the percentage of the total amount of water withdrawn

Irrigation efficiency means amount of water that needs to be applied in addition to the plant requirements for a particular type of irrigation system to meet the component system losses. It is expressed as the ratio of water used beneficially by the plants to the volume delivered for use.

Irrigation efficiency means a ratio between the amount of water effectively used for crop growth to the amount diverted from the source;
