KARSYS: a pragmatic approach to karst hydrogeological system conceptualisation. Assessment of groundwater reserves and resources in Switzerland, 2013, Jeannin P. Y. , Eichenberger U. , Sinreich M. , Vouillamoz J. , Malard A. , Weber E.

An approach is presented for the hydrogeological conceptualisation of karst systems. The KARSYS approach helps hydrogeologists working in karst regions to address in a pragmatic and efficient way the three following questions. (1) Where does the water of a karst spring come from? (2) Through which underground routes does it flow? (3) What are the groundwater reserves and where are they? It is based on a three dimensional model of the carbonate aquifer geometry (3D geological model) coupled to a series of simple fundamental principles of karst hydraulics. This provides, within a limited effort, a consistent hydrogeological conceptual model of karst flow systems within any investigation area. The level of detail can be adjusted according to the targeted degree of confidence. Two examples of its application are presented; the approach was first applied with a low level of detail on a national scale in order to assess the groundwater reserves in karst aquifers in Switzerland, suggesting a groundwater volume of 120 km3. On a regional scale, it was applied with a higher level of detail to some selected karst systems in order to assess their hydropower potential. The KARSYS approach may provide very useful information for water management improvement in karst regions (vulnerability assessment, impact assessment, water supply, flood hazards, landslides, etc.). It leads, in a very cost-effective manner, to a new and highly didactic representation of karst systems as well as to new concepts concerning the delineation of catchment areas in karst regions.

Role of soil cover and epikarst on karst groundwater recharge: an experimental approach conducted on the Milandre underground laboratory (Jura Mountains, Switzerland), 2013, Jeannin Pierreyves, Huselmann Philipp, Ltscher Marc

The Milandre underground river is recognized as a site of high patrimonial value and is monitored for many parameters since 1990. The recent construction of a highway in-cluding a tunnel portal 50 meters above the cave galleries induced a series of dedicated observations. Among them, was the monitoring of flow conditions at a series of inlets at cave roof in the part of the cave located directly below the road. Water discharge and CO2 concentrations have been monitored for 5 years before the highway construction, 5 years during the road construction and 3 years after. The effects of the removal of the soil and epikarst, as well as the sealing of the surface could be observed in the cave, implying significant changes in the regime of the water inlets in the cave. As this effect was predicted and confirmed by observations, it was decided to build an injection sys-tem below the road in order to artificially feed this part of the cave which is highly dec-orated with active speleothems. The injection system is operating since October 2011 and several tests are being conducted in order to adjust discharge and CO2 concentra-tions of the injected water. Cave inlets clearly react to injections, but the control of CO2 concentrations is still difficult to fix. A modeling of recharge before, during and after the road construction has been attempted. Changes in the recharge parameters accord-ing to the three situation of the construction could be assessed. The model should be improved in order to take CO2 and possibly temperature transfer into account.
Investigations related to the dimensioning and construction of the injection system, as well as experiments, which can be conducted using this system are very valuable for better characterizing diffuse recharge of karst systems.

Combining 3D geological boundaries and fundamental hydraulic principles (KARSYS) in a GIS procedure to depict flow-systems in a karst region, 2013, Jeannin Pierreyves, Malard Arnauld

Interpretation of hydrogeological functioning of a high karst plateau using the KARSYS approach: the case of Trnovsko-Banjška planota (Slovenia), 2013, Turk Janez, Malard Arnauld, Jeannin Pierreyves, Vouillamoz Jonathan, Masini Jean, Petrič Metka, Gabrovšek Franci, Ravbar Nataša, Slabe Tadej

The high karst plateau of Trnovsko­Banjška planota is one of the most important reservoirs of karst water in Slovenia. Almost all important karst springs in this area are captured for water supply. A sustainable management of this source of groundwater is of strategic importance, not only as drinking water supply but also for the economy. For these reasons, many hydrogeological monitoring studies have been carried out over the last decades. However, no consistent regional overview of the hydrogeological functioning of Trnovsko­Banjška planota was available and we decided to study this area with more direct approach based on 3D geological and hydrogeological models. The so called KARSyS approach was developed in Switzerland and applied primarily to characterize groundwater reserves within a karst massif, and to sketch the main flow­paths carrying groundwater from recharge areas to the respective springs. The delineation of spring catchment areas in karst regions was better defined and interactions between catchments were interpreted. These results can be used to improve the management of karst waters in the studied area.
