Hol van termálkarsztvíz a Bükk-térségben?

Abstract

The thermal karst of Bükk Mountains is the 2nd largest thermal karst water body in Hungary. It joins an extensive open karst containing cold water. There also is a tepid (lukewarm) water zone with gradual transition. The geothermal heat-flow beneath the cold karst water is as low as 40-60 mW/m², and the 30 °C isotherm (used as a technical boundary) sinks lower than 1300 m below surface, thus generating the worst rate in Hungary. The large amount of cold karst water situated in karstic rock originates from precipitation and can cool its environment very strongly. That is the reason why we must be very careful when exploiting thermal karst water. It might happen that the water yielded will not have sufficient temperature, or, in case of exploiting karst water from great depths, it can carry risks with regards to the cold karst water supplies which is crucial for communal use.
