The paper describes methodology of hydrogeological modelling of Raba river watershed, about 1565 km2 area, in flysch Outer Carpathians. Hydrodynamic model was a first step in procedure of point out groundwater bodies threatened with the risk of not achieving the European Water Framework Directive environmental aims. There was accepted conceptual model of recharge and groundwater circulation in fissured-porous sandstone-shale material, assuming that groundwater circulation could be reduced to a one aquifer in surface part of flysch rocks, connected with quaternary river valleys. There was adopted effective infiltration coefficient of selected types of surface material. There was pointed the importance of comparison the recharge defined by the infiltration method with underground runoff to rivers described by Wundt-Kille hydrological methodology. There was mentioned the effect of model scale on the precision of hydrogeological conditions projection.
