Baetic Cordillera and Guadalquivir Basin

1984
The Baetic Cordillera constitutes the main structural unit of the south of the Iberian Peninsula, extending for 600 km from the Strait of Gibraltar to Cabo de la Nao (see Fig. 13.1). In its north-eastern part, it merges with the Iberian Cordillera while to the north and north-west it is separated from the Hercynian block by a triangular depression ...

Screening of currently used pesticides in water, sediments and biota of the Guadalquivir River Basin (Spain)

open access: yesJournal of Hazardous Materials, 2013
The occurrence of 50 currently used pesticides and their transformation products in surface and waste waters, sediment and fish in the Guadalquivir River Basin was determined in 2010 and 2011. After selective sample extraction, pesticides were identified and quantified by liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS).

Value of Irrigation Water in Guadalquivir Basin (Spain) by Residual Value Method

Water Resources Management, 2011
This paper presents an application of residual value techniques to the economic analysis of irrigation water at the basin level for the Guadalquivir River (Southern Spain). The methodology is simple; the results are robust and consistent with alternative method findings.

A new approach to AVO analysis and its application in the Guadalquivir Basin, Spain

The Leading Edge, 1999
This article introduces a new AVO methodology that allows the interpreter (thanks to pseudo-3-D visualization modules) to handle real data and to avoid limitations imposed by techniques based solely on seismic processing.

Pesticide concentrations in the waters from a section of the Guadalquivir River Basin, Spain

Environmental Toxicology and Water Quality, 1997
When surface water is used to supply urban settlements, exhaustive studies of the composition of the source are necessary to ensure its potability, and to assess the possible environmental effects associated with contamination by pesticides. The present study centers on the pesticide content of the waters from a section of the Guadalquivir River and ...

Monitoring of pharmaceutically active compounds on the Guadalquivir River basin (Spain): occurrence and risk assessment

Journal of Environmental Monitoring, 2011
Guadalquivir River (South of Spain) is among the major freshwater sources of the European Atlantic basin. Until now scientific efforts have been focused on contamination by heavy metals and some priority pollutants in Guadalquivir River. However, the presence of "emerging contaminants", such as pharmaceutically active compounds, has not yet been ...

On the occurrence ofAnaecypris hispanica, an extremely endangered Iberian endemism, in the Guadalquivir River basin

Journal of Fish Biology, 2010
The jarabugoAnaecypris hispanica, considered endemic to the Guadiana River basin, has been found in the Guadalquivir River. First genetic data showed a high degree of similarity to those of the Guadiana River populations. The genetic study recovered five different groups of haplotypes, the Guadalquivir River specimens belong to the largest and most ...

A new Pliocene ostracod species from the Guadalquivir Basin (SW Spain)

2018
A new ostracod species from Pliocene sediments of the Gualdalquivir Basin (SW Spain), Cyprideis civis nov. sp., is herein described and illustrated. This new species is distinguished in having small size (length: < 820 μm; height < 460 μm) and strongly reticulated valves and a small size in comparison with other species of this genus.

Patterns of reservoir operation over a 20-years period in the Guadalquivir basin and implications for basin management

Water management in basins where natural flow regime is altered by the presence of reservoirs is a complex issue that often requires the development of modelling tools to support managers in their decision-making process. However, when it comes to large basins where it is necessary to satisfy the different demands of a vast and heterogeneous territory,
