Presentation
Full-text available
The time series data from gauging stations in the basin made it possible to assess the state of the aquifers and relating it to human overexploitation and potential climate change. This study is part of the Project 'Nature-based Solutions for the management of the river Guadaira' and it is supported with European Regional Development Funds (FEDER...
Poster
Full-text available
The project "Nature-based solutions for the management of the Guadaíra river" (SbN) tries to describe the reality of the Guadaíra river (Andalusia), a basin that allows the development of multiple populations in the only uninterrupted green structure that connects the mountains of Cádiz and Malaga with the Guadalquivir estuary and Doñana. We try to...
Article
Full-text available
The geographic location of Andalusia, bordered by the Atlantic Ocean and the Mediterranean Sea, and its great topographic and climate diversity enable the analysis of different factors that condition the isotopic composition of precipitation and groundwater. Forty‐two karst springs representative of the main carbonate aquifers were selected in orde...
Preprint
Full-text available
The evolution from Pleistocene to the Present of the main springs in a slope karstic aquifer (with an altitudinal difference and where the phreatic zone affects only the base of the slope) is studied in two different systems: Fuente Alta and La Natividad. The consequence of the evolution of the slope in Fuente Alta area is the existence of successi...
Article
Full-text available
Water temperature in 40 springs that drain the most important karst massifs in Andalusia is between 9.8 and 27.5 ° C; nevertheless, 75% of flow drained by these aquifers has a temperature from 12 to 18 ° C. Water temperature is similar to the mean environmental temperature (lapse rate of-0.49 °C/100m), although there are small differences, often in...
Article
Full-text available
The physical limnology of a shallow pond system was characterized using field measurements of water temperature, pH, and electrical conductivity (EC). We determined the spatial variability in surface and groundwater temperature, pH, and EC along the pond’s shore and along the several pond-shore transects, analyzed the water column temperature gradi...
Conference Paper
Full-text available
La cuenca alta del río Bérchules tiene unas marcadas características geomorfológicas que han condicionado la formación y el funcionamiento de un acuífero superficial, que en buena medida controla el régimen de funcionamiento hidrológico del río Bérchules. En la cabecera de la cuenca surgen numerosos manantiales asociados al manto de derrubios perig...
Article
Andalusia's lowland countryside has a network of small geographically isolated playa lakes scattered across an area of 9000 km2 whose watersheds are mostly occupied by clayey rocks. The hydrological model proposed by the authors seeks to find equilibrium among usefulness, simplicity, and applicability to isolated playas in a semiarid context elsewh...
Article
We have selected three main wetland systems located in southern Spain to describe the tectonic factors that have given rise to the formation of closed depressions originating playa - lakes in a semi arid climate context. The three wetlands are located in the provinces of Córdoba, Seville and Cádiz (Andalusia). The low-permeability of the materials...
Article
Full-text available
Along-strike and traverse variations of the structural relief can be explored as the result of the coexistence of deformation structures with very different local tectonic regimes. Neotectonic regions with dominant conformable reliefs make easier to establish the relationships between structural and topographic relief and the combined use of geomor...
Article
We analyzed the main morphometric, climatic and hydrochemical characteristics of 48 ponds and playa-lakes of the semi-arid Guadalquivir River basin (southern Spain). Based on a simple conceptual model we were able to develop a Hydrological Function Index (HFI) that relates the effective rainfall in each playa-lake to its watershed (WS). We verified...
Article
This study is based on in situ measurements of the soil and the vadose zone (<60 m) in a Mediterranean karst experimental site near Nerja Cave (a show cave in dolomite marbles in southern Spain). Air temperature, relative humidity, and CO(2) concentrations are the main variables measured, especially their variations with depth in a number of boreho...
Chapter
Sierra de Segura is an extensive mountain range, about 3000 km2 in area, with 800–1200 mm/year of precipitation and groundwater resources assessed as 236 hm3/year. Calar del Espino forms a small and representative hydrogeological unit that discharges almost all groundwater flow through the El Tejo spring. Carbonate rocks nearly 500 m thick are expo...
Article
Tectonic Controls On The Development Of Continental Playa-Lakes Of The Guadalquivir River Basin (Betics, Spain). Low permeable materials belonging to both the Olistostromic Unit (OU) and the Subbetic Zone (SZ) of the Betic orogen (southern Spain) define an ENE-WSW band located in the external part of the foreland fold-and-thrust belt. A notable hyd...
Article
The main morphometry hydrogeochemical and climatic indexes were analyzed in 26 ponds of the of the Guadalquivir basin, related to the materials of the subbetic front. It has been verified that, in most cases, the surface basin (CVS) is the hydrologie unit from which these ecosystems receive the surface and ground water inputs. Therefore, the CVSs c...
Article
The carbonate aquifers of Lora and Mingo form part of the hydrogeological unit of Sierra de Estepa (SE Spain). By means of time series analysis and a 1D numerical groundwater model, groundwater exploitation was quantified and the mean annual recharge in both systems was estimated (2001-2004). During this period, the Lora and Mingo aquifers received...
Article
Summary Sierra de Segura (Betic Cordillera), with a total area of over 3000 km2, is the source of the two principal rivers in southern Spain, the Guadalquivir and the Segura. Due to the orographic effect of these mountains, precipitations are considerably more abun- dant than in nearby lowland areas, where the climate is semi-arid. Sierra de Segura...
Article
By means of a simple water balance model, together with hydrogeochemical and morphological interpretation, the hydrogeological characteristics of a series of playa lakes forming an endorheic complex within the Guadalquivir river basin in Southern Spain (La Lantejuela) have been evaluated. The lakes are demonstrated to be groundwater-dependent ecosy...
Article
The groundwater resources of the aquifer of the Aracena mountain range (Huelva) are being studied in detail by the Spanish Geological Survey. In these studies the hydrochemistry plays a pivotal role and contributes to validate the hypotheses of hydrogeological functioning based on hydrodynamic data. Several sampling campaigns have been made to char...
Article
Full-text available
The analysis and interpretation of physical and limnological parameters combined with hydrochemical (major ions and stable isotopes) analyses enabled us to evaluate the hydrogeological functioning and the hydrogeochemical evolution of groundwater in two adjacent lakes related to a karstic aquifer (Archidona, southern Spain). Lake water, groundwater...
Article
Playa lakes occur in arid and semi-arid climates and have a significant economic, ecological and cultural value. They are particularly vulnerable to changing hydrologic regimes due to climate change or human activities. We determined the hydrological regime of 10 playa lakes in southern Spain based on water budgets for a 5-year period (1997–2001)....
Article
This study presents the results of 10 years of field investigation in Fuente de Piedra Playa Lake located in southern Spain. These field observations along the playa’s shore revealed evidence of a forced convective flow and the existence of density interface below the playa basin. An upward flux of groundwater from underlying formations could be a...
