Abstract

The paper is focused on making an integrated evaluation of hydraulic and energetic management in urban landscapes with the intention of detecting consumptions which are far from those recommended as best. The method is based on indentifying hydrozones inside plots and calculating their water needs. Additionally, an assessment methodology based on catch-can testing and quality irrigation indicators are proposed to appraise irrigation efficiency and uniformity. Finally, some energetic performance indicators for evaluating irrigation supply systems are defined. The protocol has been conducted in the gardens of the Universitat Politècnica de València (Spain) and a potential saving of 43% in water consumption could be achieved. Quality irrigation and energy performance was assessed and showed that the system is not operated under the optimum conditions.
