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.
The underground geothermal conditions can be presented, irrespective of the aquifers' position, with the appropriate geothermal maps. These maps represent the expected isoterms at a depths and are derived from Geothermal maps - Expected temperatures , which are made with data from 302 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. The distribution of boreholes, which were useful for the measurement of temperature, is very uneven and different as regard the depths.
Layer shows discontinuities in the geological structure, and characterizes them according to their type and observation method.
Geophysical cross sections show the geophysical characteristics of the sediments and bedrock at depth.
Geological Units are polygons, defined by equal composition (lithology) and age.
