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
From June 2014 to May 2019, following the bifurcation of United Andhra Pradesh into the present-day residual Andhra Pradesh and Telangana, the Irrigation Minister of Andhra Pradesh was Devineni Uma Maheswara Rao of the Telugu Desam Party.
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.
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 ...
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;
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.
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 ...
Point drainage, which intercepts water at gullies (points). Gullies connect to drainage pipes beneath the ground surface, so deep excavation is required to facilitate this system. Support for deep trenches is required in the shape of planking, strutting or shoring. Channel drainage, which intercepts water along the entire run of the channel.
