ESPINOSA ESPINOSA, Bartolomé; FLORES MAGDALENO, Héctor; ASCENCIO HERNANDEZ, Roberto  e  CARRILLO FLORES, Guillermo. Design of a system of farm hydrant with the Turns and Clement methods: technical and economic analysis. Terra Latinoam [online]. 2016, vol.34, n.4, pp.431-440. ISSN 2395-8030.

The optimal and sustainable use of water resources available for irrigation requires that the irrigation facilities are able to manage water with appropriate strategies for each situation. This aspect, is absolutely necessary to make profitable investments in infrastructure for crops in irrigated areas and because of the evolution of policies and agricultural markets. For this reason, the objective of this study was to perform a technical and economic analysis of a plot hydrant irrigation system design using the Turns and the Clement methods in the module Yurecuaro of Irrigation District 087, located in the state of Michoacán, Mexico, in order to recommend a better design solution for irrigation systems. Analysis of the results shows that the hydraulic design by the Turns method requires smaller pipe diameters to operate, while the design using the Clement method requires larger diameters that allow greater flexibility in the irrigation system. The initial investment cost of the irrigation system designed with the Clement method was 28% higher than that with the Turns method. Operating costs of irrigation using the Turns method were 12.5% higher than the costs using the Clement method.
