Abstract

Varaždin aquifer is developed in the far western part of the heterogeneous Quaternary deposits in Drava basin. Water captured from this gravel aquifer is used for water supply of major cities. Recent regional problems of water supply and water source protection prompted new interpretations of the structure of deposits and hydrogeological relations in this area. Research has been focused especially on clay interbed that separates Varaždin aquifer in two isolated gravel layers. Geophysical measurements have been carried out followed by drilling of new exploration boreholes. These studies have shown new insights and enabled detailed display of clay interbed within Varaždin aquifer.

Keywords
