“…Thus, a key issue is to simulate, in an accurate manner, the performance of the irrigation systems under different head pressures. To this end, [39] has developed the tool PRESUD-irregular, which performs hydraulic and energy analyses of drip and solid set irrigation systems for any shape of plot and topography, determining the discharge and pressure of all the emitters for any pressure at the subunit inlet. With these data, quality parameters of the irrigation events can be accurately determined.…”

The carbon footprint and energy cost of irrigation are increasing due to the modernization of irrigation systems, which also necessitates highly efficient use of water resources. Alternatives to conventional energy sources to power irrigation systems are renewable sources, primarily photovoltaic energy. Photovoltaic energy has the main disadvantage of producing a highly variable amount of energy, which affects the irrigation uniformity. Modeling irrigation systems in an integrated manner generates useful information about system performance for technicians that helps in the decision-making process. The EVASOR (EVAluation of SOlar iRrigation systems) model integrates different modules to simulate the whole solar irrigation system using a holistic approach: (1) I-Solar, which simulates the instantaneous power generated by the photovoltaic system, (2) AS-Solar, which simulates the variable speed pumping system, (3) Solar-Net, which simulates the hydraulic performance of the water distribution network, and (4) PRESUD-Irregular, which determines the discharge and pressure of all the emitters of the subunits together with irrigation quality parameters (coefficient of uniformity (CU), emission uniformity (EU), and coefficient of variation of the emitter discharge in the subunit (CVq) for any pressure at the subunit inlet. The integrated model EVASOR determines the irrigation quality parameters of complex irrigation systems with information on irradiance, air temperature, wind speed, and water table level for any combination of open subunits. To validate the model, results are presented regarding a case study located in southeast Spain.

Smart City Park Irrigation System: A Case Study of San Isidro, Lima—Peru

Water management has become a global priority in recent decades. The demand for water resources is increasing in cities due to the increase in population and the intensive use of water in economic activities and ornamentation. The problem is exacerbated when cities are built on desert regions, this is the case of Lima which is the second largest city built on a desert after Cairo. In this type of cities, it is necessary to minimize water consumption in activities that do not cover the priority needs of the population. For this reason, one of the most important tasks in the management of water resources in Lima is the optimization of water use in irrigation of parks, malls and other public green areas, necessary to offer a good quality of life to citizens. This research develops a smart decision support system to optimize irrigation in city parks. The proposed methodology takes 4 variables: land area, temperature, park humidity and weather forecast. First, strategic segmentation of the total area of the park is carried out, followed by the use of low-cost sensors to construct real-time humidity and temperature maps of the land area. Afterwards, a fuzzy inference system (FIS) that incorporates the knowledge of agronomists to process vague information in terms of computer interpretable language, together with the data collected from the variables and humidity and temperature maps is built, to assess the need for irrigation of each segment of the park. A dashboard is made to facilitate the visualization of results, including humidity and temperature maps, the weather forecast for the area and the recommendation of the FIS, which supports decision-making on irrigation needs in each segment of the park. The methodology was applied in a case study that corresponds to a San Isidro park in the city of Lima. Significant expected savings were obtained in terms of water resources and monetary units, which demonstrates the viability of the application of this smart system oriented at supporting decision-making on smart irrigation in the city’s parks.

“…Under the traditional design paradigm, design and operating costs are not a design criteria but the result of the hydraulic requirements. Some, including Carri on, Tarjuelo, Hern andez, and Moreno (2013), Carri on, Montero, Tarjuelo, and Moreno (2014) and Moreno, del Castillo, Montero, Tarjuelo, and Ballesteros (2016), have studied the relationship between costs and the design of drip irrigation units, but they do not provide analytical expressions for the optimum economic calculation. There is little research that put the economic variables at the heart of the drip irrigation system design.…”

A novel approach for the design of drip irrigation systems is presented. The diameters of the laterals and submains were calculated by minimising an objective cost function that includes investment and operating costs of drip irrigation units. Diameters, head loss and its distribution between laterals and submain, average operating pressure head, upstream end energy head and the distribution uniformity were all deduced from an economic approach. These variables are not matched alone but are the consequence of the economic optimisation. Several examples with self-compensating and non-compensating emitters fed from either a pump station or a water reservoir are presented to illustrate the feasibility of the proposed methodology.
