Evaluation of risk factors in fatal accidents in agriculture
(Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria (INIA), 2010) Artículo / ArtikuluaEn el ámbito agrario se producen anualmente muchos accidentes mortales, no siendo todos ellos registrados oficialmente como accidentes laborales. El objetivo de esta investigación es comparar los datos reales y oficiales ... -
Evaluation of surface roughness parameters in agricultural soils with different tillage conditions using a laser profile meter
Surface roughness crucially affects the hydrological and erosive behaviours of soils. In agricultural areas surface roughness is directly related to tillage, whose action strongly affects the key physical properties of ... -
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 ... -
Evaluation of TOPLATS on three Mediterranean catchments
Physically based hydrological models are complex tools that provide a complete description of the different processes occurring on a catchment. The TOPMODEL-based Land-Atmosphere Transfer Scheme (TOPLATS) simulates water ... -
Evaluation of topographic correction algorithms on satellite images
Este trabajo contribuye al previamente limitado conocimiento acerca del rendimiento de los métodos de corrección topográfica proponiendo una nueva metodología de evaluación basada en imágenes sintéticas. Esta nueva metodología ... -
Factors controlling sediment export in a small agricultural watershed in Navarre (Spain)
It is recognised that the hydrological and erosion processes in watersheds are very much conditioned by the (inter)action of a number of variables. This paper covers a 15-year period of studying those factors that have ... -
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 ... -
Geometric locus associated with thriedra axonometric projections. Intrinsic curve associated with the ellipse generated
In previous work on the axonometric perspective, the authors presented some graphic constructions that allowed a single and joint invariant description of the relations between an orthogonal axonometric system, its related ... -
Gully geometry: what are we measuring?
Much of the research on (ephemeral) gully erosion comprises the determination of the geometry of these eroded channels, especially their width and depth. This is not a simple task due to uncertainty generated by the wide ... -

El presente estudio describe el hallazgo de 31 nuevas estelas de Navarra. -
Hydrological signatures based on event runoff coefficients in rural catchments of the Iberian Peninsula
Hydrological signatures are indices that help to describe the behavior of catchments. These indices can also be used to transfer information from gauged to ungauged catchments. In this study, different approaches were ... -
Influence of surface roughness measurement scale on radar backscattering in different agricultural soils
Soil surface roughness strongly affects the scattering of microwaves on the soil surface and determines the backscattering coefficient (σ 0 ) observed by radar sensors. Previous studies have shown important scale issues ... -
Influence of surface roughness sample size for C-band SAR backscatter applications on agricultural soils
Soil surface roughness determines the backscatter coefficient observed by radar sensors. The objective of this letter was to determine the surface roughness sample size required in synthetic aperture radar applications and ... -
Influence of surface roughness spatial variability and temporal dynamics on the retrieval of soil moisture from SAR observations
Radar-based surface soil moisture retrieval has been subject of intense research during the last decades. However, several difficulties hamper the operational estimation of soil moisture based on currently available ... -
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. ... -
Mathematical models to describe the volumetric shrinkage rate of red beans during drying
The present study aimed to determine the volumetric shrinkage rate of bean (Phaseolus vulgaris L.) seeds during air-drying under different conditions of air, temperature and relative humidity, and to adjust several ... -
Metodología interna en la formación académica
Se define la metodología interna de la formación académica como un plan de investigación que permite mejorar el rendimiento académico de una forma continua y autónoma. Por tanto, dicha metodología permite al docente ... -
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 ... -
Multi-criteria evaluation of topographic correction methods
In the last decades, several topographic correction methods (TOC) have been proposed, but there is not an agreement on the best method. Furthermore, different evaluation criteria have been used in the past, and there is ... -
A multi-year analysis of traffic accidents involving agricultural tractors
The agricultural sector in Spain is responsible for a high rate of accidents every year, and many of them are traffic accidents. Tractors are a relatively rare sight on roads, meaning that the incidence of accidents involving ...
