Karst aquifers provide drinking water for 10% of the world's population, support agriculture, groundwater-dependent activities, and ecosystems. These are characterised by complex groundwater-flow systems, hence, they extremely vulnerable protecting them requires an in-depth understanding systems. Poor data accessibility has limited advances in karst research realistic representation processes large-scale hydrological studies. In this study, we present World Spring hydrograph (WoKaS)...
The fluorescence index called the Transit Time (TTi) is based on of natural organic matter in order to qualitatively assess transit time karst groundwater, using springs affected by human activities. This study aims further evaluate potential fluorescent compounds as a tracer when applied unsaturated zone flows with catchments, contrast first study. For this purpose, bi-monthly sampling one year monitoring for fluorescence, TOC, major elements and water-stable isotopes was performed. A...
Core Ideas SNO KARST is dedicated to the study of karst functioning. Hydrodynamics and geochemistry are measured at springs in compartments. Process sampling was set up nine sites various climatic contexts. Continuous monitoring concerns timescales from 10 >50 yr. New tools findings due complementarity gathered data. Karst aquifers watersheds represent a major source drinking water around world. They also known as complex often highly vulnerable hydrosystems strong surface–groundwater...
Carbon dioxide and 222Rn monitoring of the atmosphere a Mediterranean sink hole - spring (SE France) during two hydrological cycles (from September 2004 to 2006) showed seasonal variations with very high concentrations summer (greater than 6% 20 000 Bq/m3, respectively). Gas dynamics in caves often show variations. Meteorological parameters (barometric pressure temperature mainly), cave geometry fracture networks control exchanges between cavity outside atmosphere. may have different sources...

Résumé L'origine de la salinité dans les eaux nappe Plio-Quaternaire plaine Ghriss (Nord-Ouest l'Algérie) et compréhension ses comportements hydrodynamiques géochimiques, en réponse à certains forçages naturels anthropiques, ont été approchées par l’étude combinée des rapports ioniques d'analyses statistiques données hydrochimiques. Cette étude a identifié l'alimentation latérale l'aquifère deux principaux aquifères région. La salinisation résulte essentiellement dissolution évaporites...
Abstract. Transit time can be estimated thanks to natural tracers, but few of them are usable in the 0–6-month range. The main purpose this work is analyze potential ratio heavy- light-weight organic compounds (the humification index (HIX); Ohno, 2002; Zsolnay et al., 1999) as a tracer short transit (Blondel 2012). Critical analysis former studies shows that although link between HIX and seems consistent, whole methodological approach needs consolidated. Natural matter fluorescence from 289...
Karst water resources, traditionally used worldwide for drinking purposes, are highly vulnerable to contamination. Scientific-technical efforts must therefore be done ensure sufficient quality human consumption. Early-Warning-Systems emerge as an effective spring scale protection strategy real-time identification of contamination episodes at capture points. With this ambition, the proposed stepwise procedure implementation site-specific (EWS), focuses on three critical features: groundwater...
Abstract. Submarine springs are a common discharge feature of the karst aquifers along Mediterranean coast. In some instances, occasional and localized saltwater intrusions can occur through submarine spring negatively impact quality groundwater resource. The hydraulic geochemical behaviour discharging into Thau Lagoon just offshore Balaruc peninsula near Montpellier, France, has been characterized to determine impacts such phenomena better understand dynamics regional aquifer improve its...
