Coupling hysteresis analysis with sediment and hydrological connectivity in three agricultural catchments in Navarre, Spain
Purpose: Rain storm events mobilise large proportions of fine sediments in catchment systems. Sediments from agriculturalcatchments are often adsorbed by nutrients, heavy metals and other (in)organic pollutants that may ... -
Runoff, nutrients, sediment and salt yields in an irrigated watershed in southern Navarre (Spain)
The environmental impact of irrigated agriculture on water quality was assessed in Landazuria watershed (Navarre, northeast Spain), a 479.5 ha watershed with 53% of irrigated agricultural land. In the framework of a long-term ... -
Comparison between capacitive and microstructured optical fiber soil moisture sensors
Soil moisture content has always been an important parameter to control because it is a deterministic factor for site-specific irrigation, seeding, transplanting, and compaction detection. In this work, a discrete sensor ... -
Temporal downscaling of test reference years: effects on the long-term evaluation of photovoltaic systems
Representative meteorological data from a given location are necessary to assess the long-term performance of photovoltaic (PV) systems. Test reference years (TRYs) or typical meteorological years (TMYs) are widely used ... -
Generation of the site-adapted clearest-sky year of direct normal irradiance for solar concentrating technologies
Concentrating photovoltaic and thermoelectric solar facilities base their operation on collecting the direct component of solar radiation. Given that the direct beam that reaches the Earth's surface varies greatly in ... -
Sustainable unfired bricks manufacturing from construction and demolition wastes
The management of construction and demolition wastes is a huge challenge for most Governments. Thegreatest component of such wastes is concrete and masonry fragments or remains. Among the most com-mon approaches to ... -
Technical and environmental characterization of hydraulic and alkaline binders
Portland cement is a widely used binder in construction and building applications because of its good properties. Despite its convenience as construction material, the social demands and policies trends are requesting a ... -
On the assimilation set-up of ASCAT soil moisture data for improving streamflow catchment simulation
Assimilation of remotely sensed surface soil moisture (SSM) data into hydrological catchment models has been identified as a means to improve stream flow simulations, but reported results vary markedly depending on the ... -
Pohlke theorem: demonstration and graphical solution
It is known that the axonometric defined by Pohlke, is geometrically known as a means of representing the figures of space using a cylindrical projec-tion and proportions. His theorem says that the three unit vectors ... -
Evaluation of the improvement of streamflow prediction through the assimilation of remotely sensed soil moisture observations
El objetivo principal de esta tesis es evaluar si la asimilacion de datos de humedad superficial del suelo obtenidos mediante tecnicas de teledeteccion, en modelos hidrologicos es capaz de mejorar la prediccion de caudales ... -
Residual stresses with time-independent cyclic plasticity in finite element analysis of welded joints
Due to the intense concentration of heat in a reduced area when Gas Metal Arc Welding (GMAW) is used to join mechanical components, the regions near the weld bead are subjected to severe thermal cycles. Firstly, the region ... -
Automatic detection of uprooted orchards based on orthophoto texture analysis
Permanent crops, such as olive groves, vineyards and fruit trees, are important in European agriculture because of their spatial and economic relevance. Agricultural geographical databases (AGDBs) are commonly used by ... -
Entendiendo el proceso de toma de decisiones de la alta dirección acerca de invertir o no en mejorar sus capacidades en gestión por proyectos
La globalización, facilitada por el transporte y las tecnologías de la información y la comunicación, han acelerado el ritmo del cambio. Las organizaciones no s ajenas a esta aceleración y tienen que evolucionar y adaptarse ... -
Analysis of the hydrological and erosive behavior of agrararian watersheds in Navarre (Spain) by experimentation and modelling
Es de general conocimiento que la actividad agraria causa un importante efecto en el medio ambiente. Se hace por tanto necesario conocer este efecto así como proponer medidas para su control. Para ello, la información ... -
Analysis of surface roughness in agricultural soils using in-situ measurements and remote sensing techniques
El término rugosidad superficial del suelo es utilizado para describir las variaciones de elevación de la superficie del suelo (micro-relieve). La rugosidad afecta diferentes procesos hidrológicos importantes como el ... -
Análisis textural de la ortofoto PNOA para la actualización de bases de datos geográficas de cultivos permanentes
Los cultivos permanentes como los olivos, las viñas o los árboles frutales son importantes en la agricultura europea desde el punto de vista de su relevancia especial y económica. En al ámbito agricola, es muy común que ... -
La atención a las emergencias en las zonas rurales. Modelos de personal operativo de los servicios de bomberos
En 2013 un estudio sobre la ubicación de los parques de bomberos en España y de su cobertura territorial identificó deficiencias en relación a la población que no dispone de atención apropiada en un tiempo considerado como ... -
Análisis de la información sobre accidentes en el sector agrario recogida en los medios de comunicación en el decenio 2004 a 2013
El presente trabajo trata de sacar a la luz muchos accidentes que ocurren en el sector agrario y a los que no se da la importancia debida haciendo que este sector parezca menos peligroso de lo que realmente es. Del ... -
Magnesium oxide as alternative binder for unfired clay bricks manufacturing
Replacement of fired bricks by unfired ones could be an effective way to reduce the building industryenvironmental footprint: Their manufacture not only requires less energy and natural resources but alsogenerates less waste. ... -
Monitoring water vapour with GNSS during a heavy rainfall event in the Spanish Mediterranean area
The Spanish Mediterranean area is periodically affected by torrential rainfall events during autumn. In September 2012, one of these episodes took place with up to 50 mm of rain in a 1-hour period and with more than 300 ...
