Groundwater vulnerability maps represent an essential tool for protecting karst groundwater resources. Vulnerability
assessment is usually based on spatial evaluation of various parameters that affect the vulnerability degree and regulate
the protection role of the unsaturated zone. Most of these parameters, like soil and geology conditions, are constant
and do not change during the year or over several years. In contrast, some parameters, such as the groundwater level,
depend on the variability of recharge conditions. By considering the variability of groundwater parameters, vulnerability
maps are significantly changed, regardless of the applied vulnerability assessment method. In such circumstances,
the obtained groundwater vulnerability maps can reflect the vulnerability degree in different water stages. According
to the state of accumulation of karst groundwater, these maps can be used to define protective measures and adequate
action in case of a contamination accident.
The catchment of the Perućac spring in western Serbia was selected to assess groundwater vulnerability in two characteristic
water storage in the karst aquifer during the hydrological year. The catchment area is characterized by mainly
Triassic limestone with well-developed karst porosity. The karst aquifer is primarily recharged with precipitation on
the autogenous part of the basin and several periodically active ponors with punctual infiltration. The outflow predominantly
occurs through the Perućac karst spring with a flow rate variability of 0.4 to 10 m³/s.
In these examples, two karst vulnerability assessment methods were applied to estimate groundwater vulnerability in
different water stages: PI and COP. Parameters that were found to change in time were the thickness of the unsaturated
zone (PI and COP), precipitation (COP), recharge (PI), and infiltration conditions (PI and COP). The latter parameter
has the most significant impact on groundwater vulnerability since the presence of concentrated recharge significantly
changes the natural protection degree.
Assessment of groundwater vulnerability maps based on different storage conditions in the analysed karst aquifer can
be a powerful tool for improved protection and sustainable development of karst basins and analysis of different climate
change scenarios and long-term protection.
