Análisis de sequías históricas a través de los impactos derivados

Sainz de la Maza, M.; del Jesus, M. (Universitat Politècnica de València, 2020-07-31)

[ES] A pesar de que hoy en día la identificación y caracterización de sequías sigue siendo un proceso no estandarizado, lo más habitual es utilizar índices como el SPI o el SPEI entre otros. En este estudio se han analizado ...
Calibración del Modelo Hydrus-3D para el riego localizado en suelos estratificados con cultivo intensivo (enarenado)

Zapata-Sierra, A.J.; Roldán-Cañas, J.; Reyes-Requena, R.; Moreno-Pérez, M.F. (Universitat Politècnica de València, 2021-01-29)

[EN] The development of the wet bulb under drip irrigation in sand covered soils presents a different behavior from that observed under homogeneous soils. The presence of a very active crop also imposes a series of variations ...
Estimación de la evapotranspiración real en zonas de llanura mediante productos de humedad de suelo de la misión SMAP

Walker, E.; García, G. A.; Venturini, V. (Universitat Politècnica de València, 2018-12-26)

[EN] Evapotranspiration (ET) is an important process in the water cycle and in the land-surface energy balance. Over the last decades, remote sensing has provided valuable information to quantify ET. However, methodologies ...
Estudio de la humedad del suelo con técnicas GNSS-R

Tórtola Lahiguera, Julián (Universitat Politècnica de València, 2019-09-17)

[ES] Se plantea en este proyecto el estudio de las posibilidades de la tecnología GNSS-R para la obtención de la humedad, tanto del suelo como de la vegetación, mediante señales GNSS reflejadas. Así mismo, se incorporarán ...
Multi-constellation GNSS interferometric reflectometry with mass-market sensors as a solution for soil moisture monitoring

Martín Furones, Ángel Esteban; Ibañez Asensio, Sara; Baixauli, Carlos; Blanc Clavero, Sara; Anquela Julián, Ana Belén (EUROPEAN GEOSCIENCES UNION, 2020-07-15)

[EN] Per capita arable land is decreasing due to the rapidly increasing population, and fresh water is becoming scarce and more expensive. Therefore, farmers should continue to use technology and innovative solutions to ...
Nursery location and potassium enrichment in Aleppo pine stock 2. Performance under real and hydrogel-mediated drought conditions

Campo García, Antonio Dámaso del; Hermoso de Mena, Javier; Flors, Jaime; Lidón Cerezuela, Antonio Luis; Navarro-Cerrillo, Rafael M. (Oxford University PressInstitute of Chartered Foresters, 2011-07)

This work investigates Aleppo pine performance under severe drought conditions according to seedling size and nutritional status, with special emphasis on potassium. The interaction of drought ameliorating measures such ...
On the Use of Unmanned Aerial Systems for Environmental Monitoring

Manfreda, Salvatore; McCabe, M. F.; Miller, P. E.; Lucas, R.; Pajuelo Madrigal, V.; Mallinis, G.; Ben Dor, E.; Helman, D.; Estes, L.; Ciraolo, G.; Müllerová, J.; Tauro, F.; de Lima, I.; de Lima, J.; Maltese, A.; Francés, F.; Ruiz Perez, Guiomar (MDPI AG, 2018)

[EN] Environmental monitoring plays a central role in diagnosing climate and management impacts on natural and agricultural systems; enhancing the understanding of hydrological processes; optimizing the allocation and ...
Python software tools for GNSS interferometric reflectometry (GNSS-IR)

Martín Furones, Ángel Esteban; Luján García Muñoz, Raquel; Anquela Julián, Ana Belén (Springer-Verlag, 2020-07-20)

[EN] Global Navigation Satellite System (GNSS) interferometric reflectometry, also known as the GNSS-IR, uses data from geodetic-quality GNSS antennas to extract information about the environment surrounding the antenna. ...
Riparian evapotranspiration modelling: model description and implementation for predicting vegetation spatial distribution in semi-arid environments

García-Arias, Alicia; Francés, F.; Morales de la Cruz, Marco Vinicio; Real Llanderal, Joaquín; Vallés Morán, F. J.; Garófano-Gómez, Virginia; Martinez-Capel, Francisco (Wiley, 2014-04)

Biotic and abiotic interactions between the riparian zone and the river determine relevant hydrological processes and exert control over riparian and bordering upland vegetation types. Vegetation growth and development are ...
Simultaneous soil moisture and properties estimation for a drip irrigated field by assimilating cosmic-ray neutron intensity

Han, Xujun; Hendricks Franssen, Harrie-Jan; Jiménez Bello, Miguel Ángel; Rosolem, R.; Bogena, Heye; Martínez Alzamora, Fernando; Chanzy, André; Vereecken, Harry (Elsevier, 2016-08)

Neutron intensity measured by the aboveground cosmic-ray neutron intensity probe (CRP) allows estimating soil moisture content at the field scale. In this work, synthetic neutron intensities were used to remove the bias ...
Soil moisture estimation using multi linear regression with terraSAR-X data

García, G.; Brogioni, M.; Venturini, V.; Rodriguez, L.; Fontanelli, G.; Walker, E.; Graciani, S.; Macelloni, G. (Universitat Politècnica de València, 2016-06-27)

[EN] The first five centimeters of soil form an interface where the main heat fluxes exchanges between the land surface and the atmosphere occur. Besides ground measurements, remote sensing has proven to be an excellent ...
Tendencia de la cobertura vegetacional afectada por incendios en el Parque Nacional Torres del Paine
