| Abstract: | The practically important part of geothermal systems belongs to the convective type where the thermal energy is transported by movement of water or steam. Both geothermics and hydrology should be in very close cooperation at the interpretation of convective geothermal anomalies.In the first part of the study the parameters required for the calculation of water- and thermal-balance will be enumerated and their obtainable accuracy will be discussed based mainly on the praxis used in Hungary.In the second part, heat convection problems connected to subterranean water movement will be discussed, divided into three cases which have importance in praxis: • — regional water-flow systems with great inflow and outflow areas; • — mountainous — mainly karstic — areas of infiltration with springs at the foot of the mountain; • — closed convective systems of circulation. For illustrating the conceptual examples given above, Hungarian case histories with characteristic data will be presented: The Transdanubian Middle Range, Spa of Budapest, Spa of Héviz, the Great Hungarian Plain and the Thermal Anomaly at Tiszakécske. |
