Natural resources

Natural resources - as it was mentioned before – include natural phenomena such as thermal and medicinal waters, mineral waters, sea water, medicinal clay, gases, unique climatic conditions or cave microclimate. First of all underground waters need to be surveyed

Considering their location and structure underground waters can be grouped into categories as follows: soil moisture, subterranean water, layer (stratification) water and crack water. Considering our topic the last two groups are of special significance. Layer water, or stratification water can be found between two impermeable layers of rock. Crack water (in limestones it is called karst water) is water which can be found in the cracks of rocks.
