ABSTRACT: While groundwater temperature at small depth is normally tightly connected to the surface temperature, this does not hold true in towns and cities where aquifers with shallow depth are mostly influenced by urban development so that groundwater temperature in different parts of the town is distinct to that in rural areas. Heat produced from heated basements and underground utilities was identified as the main source of higher groundwater temperature below inner-city areas. This study focuses on the capital city of Bratislava where the Slovak Hydrometeorological Institute monitoring network determines temperatures for different parts of the city and different kinds of land use. The main task was to compare surface temperatures with groundwater temperatures and analyse their correlation with different types of built up areas. Our results determined that the mean average groundwater temperature in the “Old Town” city centre is 5°C higher than in suburban and rural areas.
