Analysis of local head losses in microirrigation lateral connectors based on machine learning approaches

Martí Pérez, Pau Carles; Shiri, Jalal; Roman Alorda, Armando; Turegano Pastor, José Vicente; Royuela, Alvaro (Springer-Verlag, 2023-11)

[EN] The presence of emitters along the lateral, as well as of connectors along the manifold, causes additional local head losses other than friction losses. An accurate estimation of local losses is of crucial importance ...
Assesment of a 4-input artificial neural network for ETo etimation through data set scanning

Martí Pérez, Pau Carles; Manzano Juarez, Juan; Royuela, Alvaro (Springer Verlag (Germany), 2011-05)

Evapotranspiration is a complex and non-linear phenomenon that depends on the interaction of several climatic parameters. As an alternative to traditional techniques, artificial neural networks (ANNs) are highly appropriate ...
Combination of satellite imagery with meteorological data for estimating reference evapotranspiration

Montero, D.; Echeverry, F.; Hernández, F. (Universitat Politècnica de València, 2018-06-29)

[EN] The Food and Agriculture Organization of the United Nations (FAO) in its publication No. 56 of the Irrigation and Drainage Series presents the FAO Penman-Monteith procedure for the estimation of reference evapotranspiration ...
Estudios preliminares para la determinación del coeficiente de cultivo de la chufa

Matute Díez, Miguel (Universitat Politècnica de València, 2017-10-25)

The research team in which this Final Master's Thesis will be developed, has carried out several studies, during the last years, leading to improve the irrigation water use efficiency in chufa crop. Although these ...
Evaluación de dos modelos para la estimación de la evapotranspiración de referencia con datos CERES

Carmona, F.; Holzman, M.; Rivas, R.; Degano, M.F.; Kruse, E.; Bayala, M. (Universitat Politècnica de València, 2018-06-29)

[EN] Evapotranspiration is the most important variable in the Pampas plain. Information provided by sensors onboard satellite missions allows represent the spatial and temporal variability of evapotranspiration, which ...
Modeling reference evapotranspiration with calculated targets.Assessment and implications

Martí Pérez, Pau Carles; González Altozano, Pablo; López-Urrea, Ramón; Mancha, Luis A.; Shiri, Jalal (Elsevier Masson, 2015-02)

[EN] Due to the absence of experimental reference evapotranspiration (ETo) records, data-driven models con-sider in most cases calculated ETotargets to train and test the models, usually according to the standardFAO56 ...
Parametric expressions for the adjusted Hargreaves coefficient in Eastern Spain

Martí Pérez, Pau Carles; Zarzo Castelló, Manuel; Vanderlinden, K.; Girona, J. (Elsevier, 2015-10)

The application of simple empirical equations for estimating reference evapotranspiration (ETo) is the only alternative in many cases to robust approaches with high input requirements, especially at the local scale. In ...
Predicción de las necesidades hídricas mediante datos meteorológicos para los cultivos y la creación e implementación de programas de riego para la automatización de los sistemas de redes de distribución de agua de riego en el sector 11 de la Acequia Real de Júcar. TM de Guadassuar (Valencia)

Gules, Ahmet (Universitat Politècnica de València, 2023-10-04)

[ES] El agua es un recurso vital para la vida humana, cuya demanda ha aumentado considerablemente debido al cambio climático y al crecimiento demográfico. Alrededor del 70% del agua se destina al riego agrícola. Para abordar ...
Prediction of evapotranspiration in a Mediterranean region using basic meteorological variables

Jato-Espino, D.; Charlesworth, S.; Perales Momparler, Sara; Andrés Doménech, Ignacio (American Society of Civil Engineers, 2017-04)

[EN] A critical need for farmers, particularly those in arid and semiarid areas is to have a reliable, accurate and reasonably accessible means of estimating the evapotranspiration rates of their crops to optimize their ...
Reference evapotranspiration estimation without local climatic data

Martí Pérez, Pau Carles; González Altozano, Pablo; Gasque Albalate, Maria (Springer Verlag (Germany), 2011-11)

[EN] The Penman-Monteith equation for reference evapotranspiration (ET o) estimation cannot be applied in many situations, because climatic records are totally or partially not available or reliable. In these cases, empirical ...
