TEACHING-RESEARCH POLYGON, VELIKA GORICA
Autor: Laura Bačani, mag. ing. geol.
Groundwater reserves of the Zagreb unconfined aquifer are defined as a strategic resource of groundwater in Croatia within the Croatian Waters’ Water Management Strategy. They present the only source of potable water for the inhabitants of the City of Zagreb and one part of the Zagreb County. In the past decades, groundwater level declines have been identified in the Zagreb aquifer. Consequently, it became important to identify and quantify every single source of its recharge. In order to observe and measure the processes in the unsaturated zone a teaching-research polygon was constructed (Figure 1) in collaboration between Velika Gorica water supply system (VGV) and Faculty of Mining, Geology and Petroleum Engineering (RGNF), University of Zagreb. Polygon is located in the southern part of the Zagreb aquifer, at the Velika Gorica well field.
