Estudio topográfico, diseño y construcción de un sistema de riego por aspersión subfoliar, mediante un modelo hidráulico para determinar los parámetros de operación y suplir la sequia en plantaciones de banano

Abstract

The purpose of this work was the topographic study, design and construction of a subfoliar sprinkler irrigation system, using a hydraulic model to determine the operating parameters and supply the drought in banana plantations. For the research, the elevations of the land were obtained, the topography was made in the study area to know the altitude points of the surface, so the Qgis software was used, once this procedure was done, these altitude points were imported to the Epanet software in which the pressure and flow were determined according to the needs, after this, the hydraulic plan was made to know the pvc pipes with their different diameters and to be able to make the construction (ditches, pipe connections) in the study area and finally to be able to perform the operation tests. At each consumption point, a pressure of 15.3 mca and a flow rate of 0.122 L/s were obtained; the data obtained were approximately equal to those designed in the Epanet software. It was concluded that the pipe diameters vary from 25mm to 110mm, to meet the pressure and flow requirements at each point of consumption, the sprinklers require an optimum operating pressure of 15mca and a flow rate of 0.12 LPS. It is recommended to implement the plinth protection system; it is also suggested to provide adequate maintenance to the sprinklers to prevent them from deteriorating quickly.
