Accuracy of methods for field assessment of rill and ephemeral gully erosion
(Elsevier, 2006)
Artículo / Artikulua,
To properly assess soil erosion in agricultural areas, it is necessary to determine precisely the volume of ephemeral gullies and rills in the field by using direct measurement procedures. However, little information is ...
Progress in gully erosion research: IV International Symposium on Gully Erosion
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007)
Libro / Liburua,
The classic forms of water erosion of the soil comprise sheet, rill, and gully erosion. According to the concept most
generalized, in sheet erosion, thin layers of material are uniformly removed from the soil surface due ...
Evaluación de la aplicabilidad de la teledetección radar a la estimación de la humedad superficial del suelo en cuencas agrícolas
(2006)
info:eu-repo/semantics/doctoralThesis,
En esta tesis doctoral se aborda el tema de la estimación de la humedad superficial del suelo mediante teledetección radar. La humedad superficial del suelo es una variable que interviene en multitud de procesos que tienen ...
Effect of initial step height on headcut development in upland concentrated flows
(American Geophysical UnionWiley, 2001)
info:eu-repo/semantics/article,
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 ...
Bean moisture diffusivity and drying kinetics: a comparison of the liquid diffusion model when taking into account and neglecting grain shrinkage
(Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria (INIA), 2007)
Artículo / Artikulua,
El objetivo de este trabajo fue ajustar el modelo de difusión líquida para predecir las pérdidas de volumen de grano en el secado de judía (Phaseolus vulgaris L.). Se recolectaron granos de judía con una humedad del 0,92 ...
Error in radar-derived soil moisture due to roughness parameterization: an analysis based on synthetical surface profiles
(MDPI, 2009)
Artículo / Artikulua,
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 ...
Influence of surface roughness spatial variability and temporal dynamics on the retrieval of soil moisture from SAR observations
(MDPI, 2009)
Artículo / Artikulua,
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 ...
On the soil roughness parameterization problem in soil moisture retrieval of bare surfaces from synthetic aperture radar
(MDPI, 2008)
Artículo / Artikulua,
Synthetic Aperture Radar has shown its large potential for retrieving soil moisture maps at regional scales. However, since the backscattered signal is determined by several surface characteristics, the retrieval of soil ...
