Review: Thermal water resources in carbonate rock aquifers

Goldscheider, Nicola ; Mádl-Szőnyi, Judit ; Erőss, Anita ; Schill, Eva

In: Hydrogeology Journal, 2010, vol. 18, no. 6, p. 1303-1318

The current knowledge on thermal water resources in carbonate rock aquifers is presented in this review, which also discusses geochemical processes that create reservoir porosity and different types of utilisations of these resources such as thermal baths, geothermal energy and carbon dioxide (CO2) sequestration. Carbonate aquifers probably constitute the most important thermal water...

Comparative application of four methods of groundwater vulnerability mapping in a Slovene karst catchment

Ravbar, Nataša ; Goldscheider, Nicola

In: Hydrogeology Journal, 2009, vol. 17, no. 3, p. 725-733

Four methods of groundwater vulnerability mapping have been applied in a Slovene karst catchment and validated by tracer tests. The test site is characterised by high water table fluctuations, manifested in intermittent lakes and variable drainage divides. A first multi-tracer test (two injections) allowed subdivision of the catchment into zones of different degrees of contribution (‘inner...

Geological structure, recharge processes and underground drainage of a glacierised karst aquifer system, Tsanfleuron-Sanetsch, Swiss Alps

Gremaud, Vivian ; Goldscheider, Nicola ; Savoy, Ludovic ; Favre, Gérald ; Masson, Henri

In: Hydrogeology Journal, 2009, vol. 17, no. 8, p. 1833-1848

The relationships between stratigraphic and tectonic setting, recharge processes and underground drainage of the glacierised karst aquifer system ‘Tsanfleuron-Sanetsch’ in the Swiss Alps have been studied by means of various methods, particularly tracer tests (19 injections). The area belongs to the Helvetic nappes and consists of Jurassic to Palaeogene sedimentary rocks. Strata are folded...

A new quantitative interpretation of the long-tail and plateau-like breakthrough curves from tracer tests in the artesian karst aquifer of Stuttgart, Germany

Goldscheider, Nicola

In: Hydrogeology Journal, 2008, vol. 16, no. 7, p. 1311-1317

In 1998 and 1999, two multi-tracer experiments were conducted in the artesian karst aquifer of the mineral springs of Stuttgart, Germany. The breakthrough curves (BTCs) monitored at the springs showed very long tails or developed plateau-like concentration levels for more than 200 days. Initially, this observation was qualitatively explained by exchange between cavities with stagnant water and...

Karst groundwater protection: First application of a Pan-European Approach to vulnerability, hazard and risk mapping in the Sierra de Líbar (Southern Spain)

Andreo, Bartolomé ; Goldscheider, Nicola ; Vadillo, Iñaki ; Vías, Jesús María ; Neukum, Christoph ; Sinreich, Michael ; Jiménez, Pablo ; Brechenmacher, Julia ; Carrasco, Francisco ; Hötzl, Heinz ; Perles, María Jesús ; Zwahlen, François

In: Science of The Total Environment, 2006, vol. 357, no. 1-3, p. 54-73

The European COST action 620 proposed a comprehensive approach to karst groundwater protection, comprising methods of intrinsic and specific vulnerability mapping, validation of vulnerability maps, hazard and risk mapping. This paper presents the first application of all components of this Pan-European Approach to the Sierra de Líbar, a karst hydrogeology system in Andalusia, Spain. The...

Main concepts of the "European approach" to karst-groundwater-vulnerability assessment and mapping

Daly, D. ; Dassargues A. ; Drew, D. ; Dunne, S. ; Goldscheider, Nicola ; Neale, S. ; Popescu, I. ; Zwahlen, François

In: Hydrogeology Journal, 2002, vol. 10, no. 2, p. 340-345

In order to achieve some consistency in the establishment of groundwater intrinsic vulnerability maps in Europe, a new approach is proposed by Working Group 1 of the European COST Action 620 on "Vulnerability mapping for the protection of carbonate (karst) aquifers". A general procedure is offered which provides consistency while allowing the required flexibility for application to a continent...
