DISEÑO HIDRÁULICO DE REDES A PRESIÓN EN LOS SISTEMAS DE RIEGO, EMPLEANDO UN MODELO MATEMÁTICO.

Abstract

In northern México, has been a problem for water resources, because as you know, the distribution of this is very different from as in the south, in the northern precipitation presented are lower, preventing an average of 428 mm per year and the water used in irrigation comes mainly from that is stored in dams of the region and 92.5% is used for irrigation. Several alternatives have been developed in order to make more efficient water use in irrigation and one of them is given below, that is conducting a hydraulic design in a closed network or pressure, we have applied this hydraulic design of a network to pressure at a district north of the country which in this case is the irrigation district 041 "Yaqui River", all of which surface is sowing irrigation, which it represents a big advantage because they get more agricultural products in less time, that is we shouldn’t wait rainfall of rain to be able to cultivate. To perform a hydraulic design of a closed network using a computer-assisted mathematical model, there are several business models for the design of distribution networks, however, most need to acquire licenses with high cost for using However, we found that the model EPANET 2.0 is well suited to this work and its access is free, and it is not very complex in its use. In this thesis, we found that applying the design hydraulic with EPANET 2.0 in an system irrigation pressure is more efficient water use by 70% and that various alternatives can be proposed design is, you can change the source of supply network and using the mathematical model obtained the diameters optimal of design, and this work had the purpose of contribute to the improvement of designs hydraulic irrigation pressure.
