Implications of the spatial variability of infiltration-water chemistry for the investigation of a karst aquifer: a field study at Milandre test site, Swiss Jura

Perrin, J. ; Jeannin, Pierre-Yves ; Zwahlen, François

In: Hydrogeology Journal, 2003, vol. 11, no. 6, p. 673-686

The Milandre test site is an ideal karstic aquifer for studying the spatial heterogeneity of groundwater chemistry. Numerous observation points can be sampled: the spring, the underground river and its tributaries, and boreholes at different depths. The main causes of the spatial variability of the chemical parameters are: nature and localisation of the input, the structure of the infiltration...

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

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...
