Abstract
In the frame of research project "Impact of Urban Environment on Soil Quality and Processes in Unsaturated Zone" we plan to build a lysimeter within the Union brewery area. By this lysimeter, we plan to monitor the status and changes in quality of soil and of the unsaturated zone of the upper Ljubljansko polje Quaternary aquifer within this area. For this purpose, we will install in soil and in unsaturated zone at different depths under the land surface a series of in-situ parameters measuring captors and a series of suction tubes for pore water sampling. On the surface we will install a meteorologic station for measurement of local hydrometeorologic parameters and an artificial rain producing shower, aimed at studying the preferential flow paths of vertical percolation in the unsaturated zone. Below three different surface covers (asphalt, gravel dump and grass) we will install 126 measuring and sampling points in soil and in unsaturated zone and at least two in the saturated zone of this aquifer. We will monitor all relevant pedologic, hydrogeochemical, hydroisotopic and basic microbiologic parameters. A throughout analytical monitoring is too costly and may even in the richest countries hardly be afforded. Therefore, in order to optimise and lower the costs, we will first perform a throughout "scoping" and then design monitoring of relevant parameters accordingly. It is to be noted that the processes in the unsaturated zone are after recent findings much slower than expected. To assess any changes and trends, 5-8 years may be needed. This research project represents therefore the beginning of a longterm environmental monitoring in this area. We believe that it is innovative for the Ljubljana area and in accordance with the actual world research trends.
