ABSTRACT
The temperature of a streamwater that collects water from 4 thermal groundwater sources in Valea Băilor (Moneasa, Romania) was monitored from November 2015 until February 2016. The thermal groundwater flow crosses limestones and dolomites before reaching the topographic surface. The thermal groundwater is used for local economic purposes. The average stream temperature during November-February was 23.88°C. The standard deviation of the recorded water temperature was only 0.15°C, while the difference between the maximum and minimum values was 0.75°C. The water temperature of the thermal stream, measured at 1 m distance from the thermal springs (which are grouped together in a common constructed exurgence area) does not exhibit the diurnal oscillation of the day-night cycle recorded in the air temperature. The average air temperature recorded in Valea Băilor, near the water monitoring point, from November 2015 to January 2016 was 1.47°C. The standard deviation of the air temperature was 4.16°C, while the difference between the maximum (positive number) and minimum (negative number) values was 28°C. Longer air and water temperature time series could be used to decide if there is any correlation between the local climate and the studied thermal springs.
