ABSTRACT
ABSTRACT: An urban lysimeter has been constructed within a highly urbanised area at Union Brewery in Ljubljana (the capital of Slovenia), with the intention of monitoring and controlling the environmental impacts of industry and traffic on groundwater within a Pleistocene alluvial gravel aquifer. The physico-chemical and isotopic properties of sampled groundwater have already produced general information on the hydrodynamic functioning of the study area and on solute transport – the main flow components, the flow hierarchy and the environmental response to the flow system have been indicated. Two important flow types are identified – lateral and vertical flow. The former has an important role in groundwater protection, whilst the latter is the main influence on contaminant transport towards the saturated zone.
