Using Slim Hole Tools to Quantify Hydraulic Conductivity and to Characterize Water Circulation in a Complex Saturated Porous Aquifer Pfynwald, Wallis, Switzerland

B-12 USING SLIM HOLE TOOLS TO QUANTIFY HYDRAULIC CONDUCTIVITY AND TO CHARACTERIZE WATER CIRCULATION IN A COMPLEX SATURATED POROUS AQUIFER PFYNWALD WALLIS SWITZERLAND INTRODUCTION The characterization of boundaries and hydraulic properties of the layers through which the water flows in complex saturated porous aquifers is only possible through numerous measurements in boreholes by using specific slim hole tools. Within the framework of the research project entitled « Fluid and mass transport in porous medium: quantification and comparison of hydrogeological geophysical and hydrochemical methods. Example of the alluvial aquifer in The Bois de Finges (Pfynwald Switzerland) » financed by the Swiss
