the scarcity of irrigation water and decrease of water resources are the most important limiting factors in crop production in countries such as iran. thus, studying the optimum use of water and increasing water use efficiency are essential to the agricultural sector. the use of a low pressure hydroflume has been suggested to replace traditional surface irrigation methods. the aim of this resea...
The Loess Plateau in the northern part of Shanxi Province has uneven rainfall and large evaporation, so droughts often occur. drought restricted development local planting industry economy. Micro sprinkler irrigation advantages strong adaptability, saving water, labor land, increasing production, preventing salinization, which is very suitable for this area. This micro-sprinkler design carried ...
center pivot irrigation system is used as a modern irrigation method in different parts of iran. unfortunately due to lack of proper design and hydraulic shortcomings of the system in several agricultural lands in iran, the efficiency of the center pivot irrigation system is low or unacceptable. low system efficiency results in non-uniformity of water distribution along the lateral and on the c...
limited water resources, especially in iran, require most effective method of water use to avoid losses. one of the important parameters in irrigation is water distribution uniformity coefficient (cu) in sprinkler irrigation. cu in every irrigation depends on pressure heads (p), riser height (rh), distance between sprinklers on lateral pipes (sl), and the distance between lateral pipes (sm). th...
