The atmospheric water infiltrating the underground predetermines the water budget of small rivers catchment, groundwater and stratum water supplies and groundwater safe yield. Climate components (precipitation, evaporation, vegetation structure) fluctuation cycles affect the natural fluctuations of groundwater horizon, its amount and partially quality. Surface sediments composition, decided the velocities and amounts of infiltrated groundwater. Groundwater exploitation, usually responsible for reduction of groundwater supplies and is another important factor of groundwater dynamics in a horizon. Finally groundwater amount decided of the surface water regime sources. The goal of the present research is to evaluate the groundwater supplies in West and East Žemaičiai Plateau and Žiemgala Lowland. For evaluation used data of climate factors, sediments distribution, land using. Influence of different factor calculating was based on Lithuania Geographical Information Infrastructure date and ArcGIS 10.1 programme using. Research results show that there are direct link between precipitation amount, surface sediments and relief dissection (relief morphometric parameters), which decided surface runoff.

Keywords: river catchment; precipitation; infiltration; retention; interception; relief dissection.
