Diagnóstico del funcionamiento hidráulico del sistema de riego Porlón – El Socorro - Reservorio 67 y propuestas para su adecuada operación: Diagnóstico del funcionamiento en flujo cuasi-permanente de la red de riego Porlón – El Socorro - Reservorio 67 y propuesta de soluciones.

Abstract

The purpose of this study is to evaluate Porlón-Reservorio 67 irrigation system in quasi-permanent flow. This irrigation system is part of El Socorro community from Riobamba, Chimborazo province . This evaluation was developed through computatinal simulations using tthe free access software EPANET. Four types of scenarios were considered with three of them considered as possible solutions. The first scenario consisted of modeling the irrigation system in its current state of operation, the second scenario was based on making certain changes in the diameters of the pipelines 12-15,17,18 and 21, the two remaining scenarios were performed using the average curve, which represents the trend of the system's operation during the week. In the third scenario, a valve was placed to limit the flow rate allowing it to be regulated at 30 l/s as stipulated by the Irrigation Board of this community, this simulation was carried out for every day of the week with the average curve. The last scenario incorporated the limiting flow valve together with tha change of pipes diameters, using for the simulation the average curve. Finally, it was possible to determine the existing deficiencies in the irrigation system that has no adequate control of the flow that circulates. It was determined that a flow regulating valve should be placed as the best solution for a correct operation of the irrigation system.
