In order to determine the impact of climatic variations on several spring discharge, five karst aquifer systems were chosen in the Neuchâtel Jura (three basins over an area of 359 km2) and in the Prealps (2 basins of 4 and 10 km2 respectively). The records of air temperature, precipitation and groundwater discharge vary between 13 and 91 years. Statistical trend analyses...

Advances in biological tracer techniques for hydrology and hydrogeology using bacteriophages : Optimization of the methods and investigation of the behavior of bacterial viruses in surface waters and in porous and fractured aquifers = Utilisation de bactériophages comme traceurs en hydrologie et en hydrogéologie

Thèse de doctorat : Université de Neuchâtel : 1994 ; 1570.

This work was undertaken in the Laboratoire de Microbiologie of the University of Neuchâtel, in close collaboration with the Center of Hydrogeology (CHYN). This multi-disciplinary research project was instigated because of the growing need both for environmentally harmless hydrogeological investigation tools, and for new tracers that can be used in multitracing experiments. This work treats of...
