Abstract

MODELLING OF NATURAL CONDITIONS OF GROUNDWATER CIRCULATION IN THE LEŻAJSK REGIONAbstract. In some regions the supply of fresh water for domestic and industrial use leads to excessive exploitation of existing groundwater resources. This is the case of Le¿ajsk town upon the San River. The water management in this area requires optimization. The principal factor is the determination of renewable groundwater resources based upon the hydrogeological modelling. Among others, the modelling results in reconstruction of natural hydrodynamic conditions within the Holocene groundwater horizon and reveals the impact of exploitation of numerous groundwater intakes discharging totally about 9500 m3/24h on the aquatic environment.
