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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
Assessing hillslope-channel connectivity in an agricultural catchment using rare-earth oxide tracers and random forests models
Soil erosion from agricultural areas is a large problem because of off-site effects like the rapid filling of reservoirs. To mitigate the problem of sediments from agricultural areas reaching the channel, reservoirs and ... -
Understanding top management's decision-making on implementing project management systems: an exploratory study
Top Management’s motivation to invest in improving their organisation’s Project Management processes and practices is arguably an important under-researched phenomenon. In this paper we present the results of an exploratory ... -
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. ... -
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 ... -
Assessment of soil factors controlling ephemeral gully erosion on agricultural fields
The soil factor is crucial in controlling and properly modeling the initiation and development of ephemeral gullies (EGs). Usually, EG initiation has been related to various soil properties (i.e. sealing, critical shear ... -
Assessing soil properties controlling interrill erosion: an empirical approach under Mediterranean conditions
Soil erodibility is a complex phenomenon that comprises a number of different soil properties. However, most current (empirical) erodibility indices are based on only a few soil properties. A feasible soil characterization ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ...
