Hydrogeology and hydrogeochemistry in the alluvial aquifer of the Zagreb area (Croatia)

摘要

The aquifer of the Zagreb area is composed of gravel and sand. East of Zagreb the thickness of the aquifer reaches its maximal thickness, about 100 m. The first results of hydrogeochemical research, which is directed on the research of the different parts of the aquifer, especially the deep parts that can be used for water supply, are presented in this paper. Results show that there is an aquifer stratification with regard to the hydrogeochemical conditions in the different parts of aquifer. This is particularly emphasized with distance from the Sava River.
