Herramienta para el cálculo de caudales circulantes en redes de riego a presión y su aplicación al diseño

Abstract

Abstract:Faced with the water deficit and the uncertainties of climate change, it is very important to improve the efficiency and productivity of water use in crops. To achieve this goal, it will be essential to implement irrigation systems especially in dry places where rainfall is scarce to meet the multiple needs of the population that depend on the distribution of water in space and time. Technified irrigation systems allow to improve the management of water resources and control hydraulic variables. For the design of these systems should be made the calculations of variables such as flow rates, velocities and pressures, which allow the efficient operation of the irrigation system under pressure. Within this context, this research intends to implement a virtual tool with a friendly environment; using the JavaScript programming language, with free access. Its operation will allow the development of calculations of circulating flows by the Clément method and design irrigation networks by the uniform slope method, complying with values of speed, demand, and sufficient pressures in demanding nodes. To validate the tool, an irrigation network located in the southern part of Ecuador was selected.
