Specific annual thermal energy content for heating and / or cooling referring per surface area for borehole heat exchangers at a defined length.

Energy content available per year in a defined volume of a groundwater body for heating and/or cooling applications

Maximum yield or pumping rate of a groundwater well doublet per square meter at a given location.

Specific thermal capacity per surface area unit for borehole heat exchangers of a defined length.

Thermal capacity of a well doublet for heating and/or cooling depending on the hydraulic productivity and the thermal productivity.

Extracted water volume per hour and meter drawdown for a defined well diameter.

Extracted water volume per hour and meter drawdown for a defined well diameter.

Database contains data from gamma-spectrometry survey. Gamma-ray spectrometry survey means measurement of natural radioactive isotopes concentration i.e. potassium 40K [%], uranium 328U and 235U [ppm], thorium 232Th [ppm]; simultaneously, total gamma-ray activity was registered. This survey started in 1976 and covered about 60 % of the territory.
