Agricultural land drainage has agricultural, environmental, hydrological, engineering, economical, social and socio-political aspects (Figure 1). All these aspects can be subject of drainage research. The aim (objective, target) of agricultural land drainage is the optimized agricultural production related to: reclamation of agricultural land
The Journal of Irrigation and Drainage Engineering is a monthly peer-reviewed scientific journal published by the American Society of Civil Engineers covering irrigation engineering as a specialty area in agricultural engineering, and drainage engineering as a specialty area in civil engineering.
Practically, wheat does not require irrigation because it develops deeper roots while during the maturing period a dry soil is favorable. The analysis of cumulative frequency [6] of climatic data plays an important role in the determination of the irrigation and drainage needs in the long run.
The regular surface drainage systems, which start functioning as soon as there is an excess of rainfall or irrigation applied, operate entirely by gravity. They consist of reshaped or reformed land surfaces and can be divided into: Bedded systems, used in flat lands for crops other than rice;
Micro-irrigation, sometimes called localized irrigation, low volume irrigation, or trickle irrigation is a system where water is distributed under low pressure through a piped network, in a pre-determined pattern, and applied as a small discharge to each plant or adjacent to it. Traditional drip irrigation use individual emitters, subsurface ...
Data analyzed with the CumFreq program [13] In projects with an uncertain supply of water due to annual variations in river discharge, water users at the top (the head users) of the irrigation system (i.e. near the system's take-off point) often have preference, to a certain extent, over users at the tail-end.
Irrigation informatics is a newly emerging academic field that is a cross-disciplinary science using informatics to study the information flows and data management related to irrigation. The field is one of many new informatics sub-specialities that uses the science of information, the practice of information processing, and the engineering of ...
In the United States an irrigation district is a cooperative, self-governing public corporation set up as a subdivision of the State government, with definite geographic boundaries, organized, and having taxing power to obtain and distribute water for irrigation of lands within the district; created under the authority of a State legislature with the consent of a designated fraction of the ...
