Diseño de un sistema de riego por aspersión en el sector chorrillos, parroquia Malacatos

The present thesis work was made in the Chorrillos sector, belonging to the council two of the Campana-Malacatos irrigation system. The current state of the area was characterized and identified where, socio-organizational, socio-economic/production and irrigation aspects, were analyzed; this was helped by the applying of 30 surveys to users that belong to this council, who allowed to collect information of great importance. Inside the socio-organizational aspect, there are a total of 55 users and is made up of a directive. In addition, they lack of irrigation shifts, which, from the users point of view, is because of the irrigation system being located at a high zone where there is little surface area; in the socioeconomic-production aspect, there is a traditional agriculture where the majority of the production goes to family consumption and the rest is destined for commercialization therefore recovering the investment; in the aspect of plot level irrigation, it isn’t technified, causing water losses by deep runoff and percolation, as well as erosion, because it is handled in a traditional way (gravity) thus limiting the irrigable area. An aspersion design was made in a 0.20 ha area, based on data and information of the soil hydro-physical properties obtained at field level and in laboratory, for that, non-disturbed samples were taken in 100 cm^3 koppecky cilinders, and disturbed-samples, which were analyzed at the Agrocalidad laboratory, the determination of basic infiltration speed was by infiltrometer cilinders. In the agronomic design the corn crops hydric necessities were calculated, where the Penman-Montieth method was applied, based on data of the meteorological yearbooks of the stations of La Argelia, Cariamanga, Malacatos, San Francisco and Yangana, with an statistic series of 18 years (1992-2009), which were necessary for the calculation of reference evapotranspiration, crop evapotranspiration, irrigation sheet, time and irrigation frequency. Based on the calculations made on the agronomic design it was determined to irrigate with a frequency of 5 days and a time of 7.7 hours, to compensate a 36.1 mm sheet. In the hydraulic design, pressure losses were determined in the main, secondary and side ones, with nominal diameters of 1 1/2", 1 1/2", 1", 3/4", applying the Hazen-Williams formula, the same that had an implementation cost of $547.56, without including workforce. Keywords: aspersion irrigation, agronomic design, hydraulic design
