ABSTRACT: Bodva River area is situated in SW part of Košická kotlina (Fold of Košice). On its low lapse, Bodva River area constitutes important reservoir of groundwater which is exploited as drinking water supply for population. Therein groundwater is mainly fixed in quarternary deposits. The deposits are in form of fluvial and proluvial sand brashes. In the past, listed area was subjected to intensive hydrogeological research but this research in majority of cases does not afford reliable results. The research has elaborated hydraulic parameters of water - saturated setting by direct methods, which use data that are obtained from hydrodynamic tests. For making regional geohydraulic parameters model of listed deposits, in described situation, the most suitable method to get reliable information is undirect method of regional valuation. This undirect method is based on using approximative logarithmic parameters of permeability index Z and transmissivity index Y, which are derived from values of specific discharge or standard specific discharge.
