Caracterización del modelo HEC-HMS en la cuenca de río Arga en Pamplona y su aplicación a cinco avenidas significativas
Pamplona es una ciudad que es atravesada por el río Arga a lo largo de una llanura aluvial, que es susceptible de inundaciones cuando se producen avenidas de cierta magnitud. Ante esta situación es importante contar con ... -
Challenges in Life Cycle Assessment (LCA) of stabilised clay-based construction materials
The preference of clay-based materials for sustainable construction is well-established. The establishment ofsustainability credentials of emergent construction materials is very subjective, and most available tools are ... -
Clasificación de cultivos en la zona media de Navarra mediante imágenes radar polarimétricas
Navarra lleva años empleando la técnica de clasificación supervisada de imágenes multiespectrales de satélite para la realización de la estadística agraria. La cubierta nubosa, muy habitual en esta zona, limita e incluso ... -
Combined spatial and temporal effects of environmental controls on long-term monthly NDVI in the Southern Africa savanna
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 ... -
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 ... -
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 ... -
Demonstrating correspondence between decision-support models and dynamics of real-world environmental systems
There are increasing calls to audit decision-support models used for environmental policy to ensure that they correspond with the reality facing policy makers. Modelers can establish correspondence by providing empirical ... -
Desarrollo de productos avanzados para la misión SEOSAT/Ingenio
SEOSAT/Ingenio es la futura misión española de observación de la Tierra en el óptico en alta resolución espacial. Mientras que los productos de imagen a Nivel 1, radiancias geo-referenciadas a nivel de sensor, se encuentran ... -
Diseño de un nuevo motor de explosión de dos tiempos con etanol como combustible
Actualmente, el mecanismo en el cual están basados la mayoría de los motores de explosión mono o pluricilindricos y que montan los vehículos convencionales, es el tradicional mecanismo cigüeñal-biela-pistón. En este ... -
Effect of initial step height on headcut development in upland concentrated flows
Experiments were conducted to examine the effect of initial step height on growth, development, and upstream migration of headcuts in concentrated flows typical of rills, crop furrows, and ephemeral gullies. In a laboratory ... -
Effective roughness modelling as a tool for soil moisture retrieval from C-and L-band SAR
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 ... -
Effects of spatial sampling interval on roughness parameters and microwave backscatter over agricultural soil surfaces
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, ... -
Error in radar-derived soil moisture due to roughness parameterization: an analysis based on synthetical surface profiles
In the past decades, many studies on soil moisture retrieval from SAR demonstrated a poor correlation between the top layer soil moisture content and observed backscatter coefficients, which mainly has been attributed ... -
Estimated and real durability of unfired clay bricks: Determining factorsand representativeness of the laboratory tests
This paper presents an analysis of the representativeness of the main laboratory tests and the real dura-bility of earth-based construction materials. For this study, a natural marl soil, mixed with different per-centages ... -
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 ...
