Study Notes

General Irrigation Terminologies

This standard defines terms used in the general classification, planning, design, construction, and operations involved in irrigation.
The standard has 123 definitions for terms related to irrigation, including concepts such as access areas, active storage, afflux, and more.

Irrigation Methods

Basin irrigation: a type of surface irrigation where water is applied to the basin through a gap in the perimeter dike or adjacent ditch.
Border irrigation: a method of irrigation that makes use of parallel border strips where the water flows down the slope at a nearly uniform depth.
Drip irrigation: a method of irrigation that involves dripping water onto the soil at very low rates from emitters, where water is applied close to plants so that only part of the soil in which the roots grow is wetted.
Furrow irrigation: a method of irrigation where water runs through small parallel channels as it moves down the slope of the field.

Water Measurement and Management

Application efficiency: the ratio of the average depth of irrigation water infiltrated and stored in the root zone to the average depth of irrigation water applied.
Conveyance efficiency: the ratio between water received at the inlet for a block of fields to that released at the project's headwork.
Crop water requirements: the amount of water used in producing crops, which is the sum of evapotranspiration or consumptive use plus seepage and percolation losses.
Effective rainfall: the amount of rainwater that falls directly on the field and is used by the crop for growth and development, excluding deep percolation, surface runoff, and interception.

Dam and Reservoir Construction

Dam height: the vertical distance from the lowest point of the ground line to the dam crest.
Freeboard: the additional height of the dam provided as a safety factor to prevent overtopping by wave action or other causes.
Reservoir: a part of the system that impounds the runoff.
Storage capacity: the total capacity at normal water surface elevation.

Water Quality and Environmental Factors

Contamination: the introduction of substances not found in the natural composition of water that make the water less desirable or unfit for intended use.
Effluent: discharges from known sources, such as wastewater flowing out of a manufacturing plant, industrial plant, or domestic, commercial, and recreational facilities.
Pollutant: any substance that directly or indirectly alters the quality of any segment of the receiving water body or land resource, affecting or tending to affect adversely any beneficial use thereof.
