An artificial neural network approach to the estimation of stem water potential from frequency domain reflectometry soil moisture measurements and meteorological data

Martí Pérez, Pau Carles; Gasque Albalate, Maria; González Altozano, Pablo (Elsevier, 2013-02)

Stem water potential seems to be a sensitive measure of plant water status. Nonetheless, it is a labour-intensive measurement and is not suited for automatic irrigation scheduling or control. This study describes the ...
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 ...
Aplicación de redes neuronales artificiales para predicción de variables en ingeniería del riego: evapotranspiración de referencia y pérdidas de carga localizadas en emisores integrados

Martí Pérez, Pau Carles (Universitat Politècnica de València, 2016-05-30)

En esta tesis se presenta la aplicación de redes neuronales artificiales (ANNs) para modelar dos variables de gran importancia en la ingeniería del riego: la evapotranspiración de referencia y las pérdidas de carga localizadas ...
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 ...
Discussion of Assessment of Reference Evapotranspiration by the Hargreaves Method in the Bekaa Valley, Lebanon by Roula Bachour, Wynn R. Walker, Alfonso F. Torres-Rua, and Mac McKee

Martí Pérez, Pau Carles; Royuela, Alvaro; González Altozano, Pablo (American Society of Civil Engineers, 2015-06)
Discussion of "Hydraulic and Statistical Analyses of Design Emission Uniformity of Trickle Irrigation Systems" by Jafar Safaa Noori and Hayder A. Al Thamiry

Turégano Pastor, José Vicente; Martí Pérez, Pau Carles; Royuela, Alvaro (American Society of Civil Engineers, 2013-12)
Geometric overlapping coefcients for calculating the required emitters per plant in drip irrigation

Martí, Pau; González Altozano, Pablo; Gasque Albalate, Maria; Turegano Pastor, José Vicente; Royuela, Alvaro (Springer-Verlag, 2023-11-29)

[EN] The designer of irrigation systems must consider a complex combination of emitter type, emitter uniformity, hydraulics, topography, desired water distribution, crop salt tolerance, water requirements, water quality, ...
Improvement of temperature-based ANN models for solar radiation estimation through exogenous data assistance

Martí Pérez, Pau Carles; Gasque Albalate, Maria (Elsevier, 2011-02)

[EN] The development of new and more precise temperature-based models for solar radiation estimation is decisive, given the immediacy and simplicity associated to their input measurements and the ubiquitous problems derived ...
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 ...
Modeling the variability of solar radiation data among weather stations by means of principal components analysis

Zarzo Castelló, Manuel; Martí Pérez, Pau Carles (Elsevier, 2011-08)

Measurements of global terrestrial solar radiation (R s) are commonly recorded in meteorological stations. Daily variability of R s has to be taken into account for the design of photovoltaic systems and energy efficient ...
Multivariate statistical monitoring of ETo: A new approach for estimation in nearby locations using geographical inputs

Martí Pérez, Pau Carles; Zarzo Castelló, Manuel (ELSEVIER SCIENCE BV, 2012)

[EN] The standard equation used to calculate reference evapotranspiration (ET o) requires many parameters that are not available or reliable in most cases. Alternative equations have been developed in the literature relying ...
New Approaches for Teaching Irrigation Scheduling. Improving Understanding through Modeling Applications

Martí Pérez, Pau Carles; Shiri, Jalal; Gasque Albalate, Maria; González Altozano, Pablo (EJournal Publishing, 2017)
