Data of Geological map were reclassified into classes of IAH classification on the base of hydrogeological characteristics. IAH classification is based on description of the hydrogeological units. Firstly, based on extensiveness and productivity and secondly on type of porosity. The purpose is to provide assistance to the strategy of groundwater exploitation as to protection and water resources management.

Map represents the calculated (surface) heat-flow density (HFD) in mW/m2 with topographic correction. It is made with data from 119 boreholes from the measured temperatures in the available boreholes and measured thermal conductivity on cored rock samples from the same boreholes. The pattern of the HFD isolines is affected by numerous parameters, particularly the thermal conductivity of rocks, rock permeability and fracturing, fluid content of the rocks, and all are reflected in the measured temperature gradient in the boreholes.

Vodonosni sistem je ozemlje z geološko zgradbo, v kateri nastopata vsaj dva različna vodonosnika, z ali brez medsebojne hidravlične povezave. Na obravnavanem območju so bile meje vodonosnih sistemov prilagojene na merilo karte 1:25.000. Namenjena so zanesljivemu ugotavljanju stanja celotne pomembne prostornine podzemnih voda v državi in doseganja okoljskih ciljev, ki jih predpisuje Vodna direktiva.

The underground geothermal conditions can be presented, irrespective of the aquifers' position, with the appropriate geothermal maps. This map represents the expected temperatures at a depth of 2000 m and is made with data from 240 boreholes. It is made on the basis of measured temperatures in accessible boreholes throughout the country. However, since the temperature field depends on the geological structure in the depths and tectonic characteristics, the course of the isotherms is a result of many influences, such as thermal conductivity of rocks, permeability and fracturing of rocks, all of which are reflected in the measured temperatures in boreholes. In this depth also a radiogenic heat production in the rocks has smaller influence. The distribution of boreholes, which were useful for the measurement of temperature, is very uneven and different as regard the depths. Following the expected temperatures at a depth of 2000 m a stronger positive anomaly is in the northeastern part of Slovenia, from the line Maribor-Rogatec to the east, while in the eastern part of the Krka basin the anomaly is not so much visible any more. In the northeastern part of the country the anomaly is the result of the thinning of the Earth's crust and greater conductive heat flow from the Earth's mantle.

Podzemni geotermični pogoji se ne glede na lego vodonosnikov prikazujejo s primernimi geotermičnimi kartami. Ta karta predstavlja pričakovane globine do izoterme 150 °C in je izdelana s podatki iz 191 vrtin. Na nek način je inverzna tistim navadnim temperaturnim kartam, ki kažejo temperature v določenih globinah. Izdelana je na podlagi izmerjenih temperatur v dostopnih vrtinah po celi državi. Ker pa je temperaturno polje odvisno od geološke sestave v globinah in tektonskih značilnosti, je potek izolinij rezultat številnih vplivov, kot so toplotne prevodnosti kamnin, prepustnost in razpokanost kamnin, ki se vsi odražajo v izmerjenih temperaturah v vrtinah. Seveda pa je prepustnost in razpokanost kamnin vse manjša v večjih globinah, ki so za to karto v zahodni in južni ter delu severne Slovenije že kar velike do te izoterme. Porazdelitev vrtin, ki so bile uporabne za meritve temperature, pa je zelo neenakomerna in po globinah različna. Karta globin do izoterme 150 °C prikazuje pozitivno anomalijo v severovzhodnem delu Slovenije. Kot posledica tanjše Zemljine skorje na tem območju in višjega konduktivnega toplotnega toka iz plašča Zemlje, so tam najvišje temperature, s tem pa so obratno najmanjše globine do izoterme 150 °C.

The underground geothermal conditions can be presented, irrespective of the aquifers' position, with the appropriate geothermal maps. This map shows the expected depths of the isotherm of 90 °C and is made with data from 191 boreholes. In a way, it is the inverse of those ordinary temperature maps showing the temperature at certain depths. It is made on the basis of measured temperatures in accessible boreholes throughout the country. However, since the temperature field depends on the geological structure in the depths and tectonic characteristics, the course contours result of many influences, such as thermal conductivity of rocks, permeability and fracturing of rocks, all of which are reflected in the measured temperatures in boreholes. The distribution of boreholes, which were useful for the measurement of temperature, is very uneven, and different as regard the depths. The map of depths to 90 °C isotherm shows a positive anomaly in the northeastern part of Slovenia. As a result of thin Earth's crust in the area and the higher conductive heat flow from the Earth's mantle, there are higher temperatures and thus are inversely smaller depths to isotherm of 90 °C.
