Modelling approaches in karst hydrogeology imply a high degree of schematization, uncertainty and subjectivity due to the specific nature of karst systems. The need to protect groundwater, especially in karst, has resulted in increasing application of methods for assessing groundwater vulnerability. Vulnerability methods specially developed for karst could assess filtration conditions, anisotropy, specific infiltration, and temporal variability, enabling better characterization and understanding of the karst systems. A recently developed method is the Time Dependent Model (TDM method), where vulnerability is based on the simulation of groundwater flow through unsaturated and saturated zones and expressed through groundwater travel time.
The study demonstrates the utilization of TDM method to simulate the yield of karst springs. This procedure includes creating spatial maps for each rain event, which, in addition to GIS software, requires using Python or similar programming language to automate the entire process. The spatial calculation of recharge using the TDM method enables the creation of maps of the recharge rate for each rainy day. At the same time, calculating groundwater travel times enables obtaining information on the arrival date of infiltrated water from each part of the catchment to the spring. Summing up all the amounts of water that reach the spring on a particular day, a hydrogram of the spring discharge is obtained. The comparison of the calculated and measured spring discharges implies adjusting the TDM method's input parameters, enabling a better simulation and understanding of the entire karst system.
This approach was successfully applied to a karst spring in Western Serbia. The results show that vulnerability maps have great potential in modelling karst systems and simulating karst processes. The conducted research also validates the vulnerability map, which was previously considered the main disadvantage when these methods are applied.
