ABSTRACT: The régime of 21 springs located in quite different hydrogeological conditions, in flysh and neovolcanic rocks of Slovakia, was assessed. The aim of the analysis was to evaluate the presence of some trends in discharges, especially in the proved climatic warm period lasting in Slovakia since 1988. The presence of long term decreasing trends was proved by most of springs located in neovolcanic as well as in flysh rocks. Short term trends since 1988 were proved only by springs from flysh rocks.
