Evaluación de la aplicabilidad del año de referencia UNE-EN ISO 15927 ainstalaciones fotovoltaicas
(Fundación General de la Universidad Politécnica de Madrid, 2014) Contribución a congreso / Biltzarrerako ekarpenaEl desarrollo y expansión de las tecnologías de aprovechamiento de la energía solar hace necesario disponer de datos meteorológicos representativos de un determinado lugar que permitan predecir el comportamiento energético ... -
Evaluación de la producción de sedimentos y calidad de las aguas en cuencas agrarias de Navarra
The Government of Navarre (Spain) established a series of experimental watersheds on different sites of its territory in order to assess the impact of the agricultural activities on the environment. Hydrological/meteorological ... -
Evaluación multitemporal de métodos de corrección topográfica mediante el uso de imágenes sintéticas multiespectrales
En este trabajo se presentan los resultados de la evaluación multitemporal de varios métodos de corrección topográfica (TOC), cuya bondad se determina de forma cuantitativa mediante el uso de imágenes sintéticas multiespectrales ... -
Evaluation of 2D models for the prediction of surface depression storage using realistic reference values
Depression storage (DS) is the maximum storage of precipitation and runoff in the soil surface at a given slope. The DS is determined by soil roughness that in agricultural soils is largely affected by tillage. The direct ... -
Evaluation of a gully headcut retreat model using multitemporal aerial photographs and digital elevation models
A large fraction of soil erosion in temperate climate systems proceeds from gully headcut growth processes. Nevertheless, headcut retreat is not well understood. Few erosion models include gully headcut growth processes, ... -
Evaluation of mechanical tomato harvesting using wireless sensors
The harvesting of processing tomatoes is fully mechanised and it is well known that during harvest, fruits are subjected to mechanical stress causing physical injuries, including skin punctures, pulp and cell rupture. Some ... -
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 ... -

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 ...
