Water is the main limiting factor for groundwater-dependent ecosystems (GDEs) in drylands. Predicted climate change (precipitation reductions and temperature increases) and anthropogenic activities such as groundwater drawdown jeopardise the functioning of these ecosystems, presenting new challenges for their management. We developed a trait-based...
The Campo de Dalías is a coastal plain, which has undergone a significant change in land use and intensive exploitation of groundwater. A series of diverse data has been analyzed: aerial and satellite images (1956–2013), evolution of the water table (1973–2019), and exploitation of different aquifers (1964–2017). The results indicate: (1) increase...
Chemical and isotopic tracers are used to identify and discriminate the factors controlling the chemical characteristics of surface water in the Andarax River. Along the river, two areas are found to have distinct processes. In the Upper Andarax zone, the surface water (163–645 μS cm⁻¹) is influenced by the direct infiltration associated with preci...

están relacionadas con la naturaleza del contenido y otras por las características y
nivel de desarr...
Interactions between surface water and groundwater (SW-GW) in the Andarax catchment are complex and encourage a diversity of surface waters in the three longest watercourses. The headwaters of the river Andarax flow continuously, but it is temporal in its middle reaches and ephemeral in its lower reaches; these three reaches demonstrate the effect...
Water resources management in coastal wetlands requires the degree of interdependence between groundwater and terrestrial ecosystems to be known. This is especially so in semiarid areas where surface inflows are restricted, marine influence is marked and the evaporation rate is high. Thus, chemistry of surface waters is very variable in the Cerrill...
The construction of desalination plants along the Mediterranean coast that are supplied with seawater via pumped boreholes in coastal aquifers has given rise to novel hydrogeological situations. At the experimental site on the Andarax delta (SE Spain), a monitoring system has been set up, consisting of piezometer clusters. Piezometric level and ele...
We have investigated the potential of 2D electrical imaging for the characterization of seawater intrusion using field data from a site in Almeria, SE Spain. Numerical simulations have been run for several scenarios, with a hydrogeological model reflecting the local site conditions. The simulations showed that only the lower salt concentrations of...
An Automated time-Lapse Electrical Resistivity Tomography (ALERT) system has been developed for the long-term monitoring of coastal aquifers. This ALERT system has been permanently installed in the River Andarax, Almeria, Spain to monitor and manage the impact of climatic change and land-use practice on the underlying Quaternary aquifer. An electro...
The construction of one of the high-speed railway tunnels between Malaga and Córdoba (South Spain) beneath the Abdalajís mountains
occasioned a series of hydrogeological problems with geotechnical and environmental impacts. The double tunnel, 7,300m in
length, runs south to north across several lines of small, calcareous mountains that have a highl...
Recently, the Junta de Andalucia (Autonomous Regional Government of Andalusia) has taken on the financing of the research project given by the title of this communication. The project represents an ambitious proposal to determine, as precisely as possible, the operation of the hydrogeological system that underpins large part of the economy of Almer...
The climatic variability of southeastern Spain recently produced one of the driest periods of the 20th century, which provoked a marked decrease in river flows. A study of trends was applied to four representative rainfall stations (Granada, Almeria, Murcia and Alicante) and showed that the downward trend is generalised. Three of the stations regis...
The scarcity of water resources in semiarid regions is usually accompanied by brief periods of quite intense precipitation
that can generate potentially catastrophic floods. In such regions, the use of runoff water for aquifer recharge can contribute
to both flooding prevention and effective management of water resources. This paper presents the re...
A study of drip water from a stalactite in the Cueva del Agua (Granada, southern Spain) over four hydrological years has enabled a detailed characterization of infiltration through the non-saturated zone of this cave. The most significant aspects are: (1) The drip water regime is not seasonal, but is linked instead to slow infiltration. Sudden chan...
The contact between freshwater and seawater in coastal aquifers is studied using a relatively simple model for homogeneous aquifers. However, for real aquifers it is not so simple. The desalination plant built to supply water to the city of Almería is situated over the aquifer in the southern part of the River Andarax Delta. Its design capacity is...
The giant Geode of Pulpí (Almería, Spain) can be considered as one of the most significant recent mineralogical discoveries in terms of geological heritage. Any tourist exploitation of this mining environment should be sustainable, and the first step is to determine the feasibility of opening the interior of the geode to visitors. To achieve this o...
