Sažetak
As part of the project „Geothermal map of the Republic of Croatia”, initiated in 2007, the broader regions of the cities of Zagreb and Karlovac were investigated (approx. 5500 km2) in order to determine information on the Terrestrial Heat Flow Density (THFD).The results presented here include computation of THFD at borehole locations and maps of THFD of the investigated area. It has been determined that THFD at the borehole locations varies over a wide range and values differ from those previously published. For most of the studied area, THFD is in accordance with the mean values for continental areas. Two positive (Zagreb and Karlovac) and one negative (Žumberak) geothermal value can be singled out. The map of THFD, as presented here, is different from the previously published maps and is considerably more precise. It is determined that hydrogeothermal sources in the investigated area are not associated with THFD in the above mentioned areas.
