Effective roughness modelling as a tool for soil moisture retrieval from C-and L-band SAR
(Copernicus Publications, 2011)
Artículo / Artikulua,
Soil moisture retrieval from Synthetic Aperture Radar (SAR) using state-of-the-art backscatter models is not fully operational at present, mainly due to difficulties involved in the parameterisation of soil surface ...
Efectos de la actividad agraria sobre los recursos hídricos y la erosión del suelo. Análisis y modelado en cuencas experimentales de la zona media de Navarra
(2014)
Tesis doctoral / Doktoretza tesia,
Este trabajo caracteriza el comportamiento hidrológico y erosivo de la cuenca agraria
experimental de La Tejería del valle de Yerri en Navarra, de 164 ha. Se evalúa el
modelo hidrológico de contaminación difusa AnnAGNPS, ...
Combined spatial and temporal effects of environmental controls on long-term monthly NDVI in the Southern Africa savanna
(MDPI, 2013)
Artículo / Artikulua,
Deconstructing the drivers of large-scale vegetation change is critical to predicting and managing projected climate and land use changes that will affect regional vegetation cover in degraded or threated ecosystems. We ...
Residual stresses with time-independent cyclic plasticity in finite element analysis of welded joints
(MDPI, 2017)
Artículo / Artikulua,
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 ...
The added value of stratified topographic correction of multispectral images
(MDPI, 2016)
Artículo / Artikulua,
Satellite images in mountainous areas are strongly affected by topography. Different studies demonstrated that the results of semi-empirical topographic correction algorithms improved when a stratification of land covers ...
Effects of spatial sampling interval on roughness parameters and microwave backscatter over agricultural soil surfaces
(MDPI, 2016)
Artículo / Artikulua,
The spatial sampling interval, as related to the ability to digitize a soil profile with a certain number of features per unit length, depends on the profiling technique itself. From a variety of profiling techniques, ...
Validation of a simplified model to generate multispectral synthetic images
(MDPI, 2015)
Artículo / Artikulua,
A new procedure to assess the quality of topographic correction (TOC) algorithms applied to remote sensing imagery was previously proposed by the authors. This procedure was based on a model that simulated synthetic scenes, ...
Runoff, nutrients, sediment and salt yields in an irrigated watershed in southern Navarre (Spain)
(Elsevier, 2018)
Artículo / Artikulua,
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 ...
Automatic detection of uprooted orchards based on orthophoto texture analysis
(MDPI, 2017)
Artículo / Artikulua,
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 ...
Gully geometry: what are we measuring?
(European Geosciences UnionCopernicus Publications, 2015)
Artículo / Artikulua,
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 ...
