| description | The groundwater recharge processes were investigated in the unsaturated zone of the Ljubljansko polje
intergranular aquifer. The study based on application of environmental tracers. The monitoring of the drainage
system was established at an urban lysimeter consisting of artifiial and autochthonous sediment layers.
Groundwater was sampled with the suction cups instaled at depths of 0.3, 0.6, 1.2, 1.8, 3.0 and 4.0 m. The results
pointed out the most important factors that control the hydrodynamic processes and solute transport in the
study site where the soil cover and vegetation are missing. The physico–chemical and isotopic properties of
sampled groundwater indicated that the clayey layers have an important role in the hydraulic behaviour of the
unsaturated zone. As a consequence of a piston effect the event and pre-event water concentrate above these
layers causing lateral flw. A vertical breakthrough of this water into lower layers of the unsaturated zone could
occur through preferential paths during intensive precipitation events in dependence on pre-accumulated water
volumes. Under such conditions groundwater residence time is about 2 months in the unsaturated zone 3 m below
the surface. |
