The Duero Basin: a general overview [PDF]

open access: yes, 1996
The Duero basin occupies a large area in the north-west of the Iberian Península. It has ao approximately quadrangular shape, and three of its four corners are the sites of distinctive sub-basins that extend outwards from the main basic. The different margins of lhe sub-basins and the main basic tend to have distinctive histories of tectonic and ...

South-western Duero and Ciudad Rodrigo basins: infill and dissection of a Tertiary basin [PDF]

open access: yes, 1996
In the soult western sector of the intracontinetal Duero basin, the post-Hercynian sedimentary record consist of Upper Cretaceous to Quaternary terrestrial sediments. Climates shifted from tropical, with poorly defined seansos (end of Cretaceous), to Mediterranean (Neogene). Tertiary deposits are divided into three tectonographic completes.

Alpine tectonic framework of south-western Duero basin [PDF]

open access: yes, 1996
The tectonic activity in the south-western area of the Spanish Northern Meseta (Ciudad Rodrigo and Duero basins) during most of the Tertiary was determined by u transpressive regime that reactivated Hercynian to Late-Hercynian faults. The record of the Alpine Orogeny is complex because the sedimentary record indicates a compresive regime in the sour e ...

River regimes and recent hydrological changes in the Duero basin (Spain)

open access: yesJournal of Hydrology, 2011
[EN] River regimes are key tools in water management as they enable prediction of minimum and maximum flows throughout the year. In the Mediterranean region, flow regimes are very sensitive to climatic variations, and are likely to change with the declining precipitation and higher temperatures predicted for the future.

Lacustrine Neogene systems of the Duero Basin: evolution and controls [PDF]

open access: yes, 1996
Vertical aggradation of Neogene fluvial and lacustrine deposits occurred until the Late Neogene in central and northem areas of the Duero Basin, coeval with river incision in the southwestern corner of the basin. The whole basin became exorheic in the Latest Neogene. We have differentiated five tectonosedimentary units (TSUs) of basinal extent, bounded

Hydrogeotoxicity from arsenic and uranium in the southern Duero Basin, Spain

open access: yesJournal of Geochemical Exploration, 2017
In the southern part of the Cenozoic Duero Basin (Spain), naturally occurring arsenic and uranium in groundwater sometimes occur in concentrations exceeding the limits for potable water. Usually, concentrations of these elements are only slightly above the limit, but this is sufficient to invalidate its use as drinking water.

Temporal Stability of Soil Moisture and Radar Backscatter Observed by the Advanced Synthetic Aperture Radar (ASAR) [PDF]

open access: yesSensors, 2008
The high spatio-temporal variability of soil moisture is the result of atmosphericforcing and redistribution processes related to terrain, soil, and vegetation characteristics.Despite this high variability, many field studies have shown that in the ...

From Spatial Characterisation to Prediction Maps of the Naturally Occurring Radioactivity in Groundwaters Intended for Human Consumption of Duero Basin, Castilla y León (Spain)

open access: yesAgronomy, 2022
According to the European Council Directive 51/2013 EURATOM, the radionuclide content in human consumption waters must comply with the stated recommendations to ensure the protection of public health.

Drainage reorganization and divide migration induced by the excavation of the Ebro basin (NE Spain) [PDF]

open access: yesEarth Surface Dynamics, 2018
Intracontinental endorheic basins are key elements of source-to-sink systems as they preserve sediments eroded from the surrounding catchments. Drainage reorganization in such a basin in response to changing boundary conditions has strong implications ...
