Análisis del comportamiento hidráulico y propuestas de mejora de la red de riego de San Rafael (Sector 4 Canal Jucar-Turia)

Abstract

[ES] Históricamente la red de San Rafael situada en el subsector norte del Sector 4 de Picassent (Valencia), subzona margen izquierda del canal Júcar-Turia, ha presentado dificultades para llevar a cabo un correcto riego de las parcelas de cultivo asociadas a dicha red debido a los grandes desniveles que implican la utilización de bombas de impulsión con el respectivo consumo energético que esto conlleva. De esta manera, la red presenta zonas donde se superan o no se alcanzan los valores críticos de presión o velocidad considerados por los técnicos de la comunidad de regantes, disminuyendo el rendimiento del riego y provocando roturas de los elementos hidráulicos que constituyen la red. Para comprobar y analizar la situación actual de la red de San Rafael se ha realizado su modelo hidráulico con el programa Epanet 2.0 a partir de los datos proporcionados por los técnicos y los cálculos pertinentes, con el objetivo de llevar a cabo la simulación de este. En base a los resultados obtenidos se han estudiado las áreas más críticas de la red (San Rafael Norte y el este de San Rafael sur), planteado diversas propuestas de mejora a los problemas que presentan y justificando de forma completa cada una ellas mediante los datos obtenidos de sus simulaciones y las comparaciones respecto a la situación inicial de la red. Para terminar, también se ha realizado una valoración económica de cada una de las opciones planteadas, de forma que queden perfectamente descritas y se pueda emplear como criterio para la elección o el rechazo de las alternativas de mejora en cuanto al aspecto económico se refiere.

[EN] Historically, the San Rafael network located in the northern subsector of Sector 4 of Picassent (Valencia), a sub-area on the left bank of the Júcar-Turia canal, has presented difficulties in carrying out right irrigation of the cultivated plots associated with the network due to the large unevenness that imply the use of pumps of impulsion with the respective energetic consumption that entails. In this way, the network presents areas where the critical values of pressure or speed considered by the irrigation community technicians are exceeded or not reached, decreasing irrigation performance and causing ruptures of the hydraulic elements that make up the network. In order to check and analyze the current situation of the San Rafael network, its hydraulic model has been carried out with the Epanet 2.0 program, based on the data provided by the technicians and the relevant calculations, in order to carry out the simulation of this. Based on the results obtained, the most critical areas of the network (San Rafael North and the east of San Rafael South) have been studied, proposing various proposals for improvement to the problems they present and fully justifying each of them through the data obtained from their simulations and comparisons regarding the initial situation of the network. Finally, an economic assessment has also been made of each of the options presented, so that they are perfectly described and can be used as a criterion for the choice or rejection of the alternatives for improvement in the economic aspect.
