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...
