Resumen de Gestión del agua en sistemas de riego por aspersión en el valle de Ebro: análisis de la situación actual y simulación de escenarios
In all irrigation systems, adequate irrigation design and management are required to promote an efficient use of available water, increase crop production and minimise deep percolation losses. In this research, a contribution to water conservation in sprinkler irrigation systems was performed. An analysis of water use and irrigation performance in the Loma de Quinto District (LQD) is presented. This district is located in the Ebro valley (NE Spain), and irrigates 2,606 ha with a wide variety of sprinkler irrigation systems. This analysis represents a contribution to the Diagnostic Analysis phase of an incipient Management Improvement Program for the LQD. In Chapter I, the irrigation management problems at the LQD and the factors affecting local water management were analysed. The high cost of irrigation water in relation to crop revenues, the technical deficiencies of the irrigation systems, and the limitations imposed by the climate and soils appear to be major causes of the water management problems identified in the LQD.
