222Rn as a natural tracer to investigate recharge and groundwater flow dynamics at three Mediterranean karst systems in Southern Spain.
Fernández-Ortega, Jaime; Rovira-Medina, Juan José; De la Torre Martínez, Beatriz; Barberá-Fornell, Juan Antonio
; Mudarra-Martínez, Matías; Andreo-Navarro, Bartolomé[et al.] (2023)
Comprehensive knowledge of groundwater origin and movement into karst aquifers is crucial to establish the adequate management practices. This is of special interest in areas strongly affected by the impact of climate ... -
A common framework for the development of spring water contamination early warning system in western Mediterranean karst areas: Spanish and French sites
Fernández-Ortega, Jaime; Ulloa-Cedamanos, Francesco; Barberá-Fornell, Juan Antonio; Batiot-Guilhe, Christelle; Jourde, Hervé; Andreo-Navarro, Bartolomé[et al.] (Esevier, 2024)
Karst water resources, traditionally used worldwide for drinking purposes, are highly vulnerable to contamination. Scientific-technical efforts must therefore be done to ensure sufficient water quality for human consumption. ... -
A soft sensor open-source methodology for inexpensive monitoring of water quality: a case study of NO3− concentrations
Chaves García, Antonio Jesús; Martín-Fernández, Cristian; Llopis-Torres, Luis Manuel; Díaz-Rodríguez, Manuel; Fernández-Ortega, Jaime; Barberá-Fornell, Juan Antonio; Andreo-Navarro, Bartolomé[et al.] (Elsevier, 2025-01)
Nitrate (NO3−) concentrations in aquifers constitute a global problem affecting environmental integrity and public health. Unfortunately, deploying hardware sensors specifically for NO3− measurements can be expensive, ... -
Comparison of artificial neural networks and reservoir models for simulating karst spring discharge on five test sites in the Alpine and Mediterranean regions.
Cinkus, Guillaume; Wunsch, Andreas; Mazzilli, Naomí; Liesch, Tanja; Chen, Zhao; Ravbar, Nataša; Doummar, Joanna; Fernández-Ortega, Jaime; Barberá-Fornell, Juan Antonio; Andreo-Navarro, Bartolomé; Goldscheider, Nico; Jourde, Hervé[et al.] (Copernicus Publications (European Geosciences Union), 2023-05-23)
Hydrological models are widely used to characterize, understand and manage hydrosystems. Lumped parameter models are of particular interest in karst environments given the complexity and heterogeneity of these systems. ... -
Coupling major ions and trace elements to turbidity dynamics for allogenic contribution assessment in a binary karst system (Sierra de Ubrique, S Spain).
Fernández-Ortega, Jaime; Barberá-Fornell, Juan Antonio; Andreo-Navarro, Bartolomé (Springer, 2023-10-28)
This investigation deals with the application of a multi-technique approach combining data from turbidity, major ions, and trace elements to characterize the implications of allogenic recharge in a binary karst system and ... -
Distribution, threats and protection of selected karst groundwater-dependent ecosystems in the Mediterranean region.
Siegel, Lena; Goldscheider, Nico; Petitta, Marco; Xanke, Julian; Andreo-Navarro, Bartolomé; Bakalowicz, Michel; Barberá-Fornell, Juan Antonio; Bouhlila, Rachida; Burg, Avihu; Doummar, Joanna; Ezzine, Ines; Fernández-Ortega, Jaime; Ghanmi, Mohamed; Jourde, Hervé; Marín-Guerrero, Ana Isabel; Mhimdi, Amal; Pipan, Tanja; Ravbar, Nataša; Stevanović, Alexandra Maran; Stevanovic, Zoran[et al.] (Springer Nature, 2023-09-25)
En la región mediterránea, los ecosistemas dependientes de las aguas subterráneas de origen kárstico (KGDEs, por sus siglas en inglés) albergan hábitats de un alto valor ecológico. Aún así, se encuentran cada vez más ... -
Groundwater vulnerability to pollution in karst aquifers, considering key challenges and considerations: application to the Ubrique springs in southern Spain
Marín Guerrero, Ana Isabel; Martín-Rodríguez, José Francisco; Barberá-Fornell, Juan Antonio; Fernández-Ortega, Jaime; Mudarra-Martínez, Matías; Sánchez García, Damián; Andreo-Navarro, Bartolomé[et al.] (Springer, 2021-01-21)
Groundwater vulnerability mapping is one of the tools most often applied to analyse the sensitivity of karst aquifers to pollution. These maps aim to support stakeholders in decision-making and to promote land-use management ... -

Preliminary assessment of sediment transport and associated bacteriological contamination in a mountainous rural karst area (Sierra de Ubrique, S Spain)
Fernández-Ortega, Jaime; Barberá-Fornell, Juan Antonio; Andreo-Navarro, Bartolomé (Jaime Fernández Ortega, 2021)
Sierra de Ubrique is a karstified carbonate aquifer system developed in Jurassic limestones and dolostones located in one of the wettest regions in Spain (NE of Cádiz province). Groundwater discharge, which is mainly ... -
Preliminary Assessment Of Sediment Transport And Associated Bacteriological Contamination In A Mountainous Rural Karst Area (Sierra De Ubrique, S Spain)
In rural karst areas, where agricultural and cattle activities are developed and quite often urban waste waters are not properly treated, the high probability of groundwater pollution occurrence together with the high ... -
PRODUCCIÓN Y TRANSFERENCIA DE 222RN EN EL ACUÍFERO KÁRSTICO DE LA SIERRA DE UBRIQUE (NE CÁDIZ)
(2021-11-17)El gas radiactivo 222Rn tiene múltiples aplicaciones en hidrogeología kárstica, entre las que destaca su uso como trazador para la evaluación de procesos de recarga y transferencia de flujo subterráneo. La red de control ... -
Real-time karst groundwater monitoring and bacterial analysis as early warning strategies for drinking water supply contamination
Fernández-Ortega, Jaime; Barberá-Fornell, Juan Antonio; Andreo-Navarro, Bartolomé (Elsevier, 2023-12-22)
Karst aquifers have been globally exploited as a reliable source of drinking water but their intrinsic characteristics (concentrated recharge, high groundwater flow velocities, etc.) and the increase of anthropogenic ...
