STABLE ISOTOPE RESEARCH AS A BASIS FORLONG-TERM EXPLOITATION PLANS ON THESORSKO POLJE AQUIFER, SLOVENIA

摘要

From the hydrogeological point of view, the Sorsko polje area is a sink, fi lledwith porous conglomerate and gravel, where large quantities of groundwater areaccumulated. The Sorsko polje aquifer is one of the richest regions of groundwaterand represents an important water source reserve for the central part of Slovenia. Thedetermination of the 18O isotope composition in water (δ18O) represents an independentcompletion of previous hydrogeological investigations of Sorsko polje. Research resultsgive more reliable information about water origin, as well as about the infl uence of localprecipitation and the Sava River water on the dynamics of groundwater restoration inthe aquifer.
