This paper considers the hydrogeological simulation of groundwater movement in karstic regions using a hydrological modelling system (SHETRAN), which has been adapted for modelling flow in karstic aquifers. The new model has been developed and used within the STALAGMITE (Sustainable Management of Groundwater in Karstic Environments) project, funded by the European Commission. The project has wide-ranging objectives covering: groundwater pollution and land-use management in karstic areas; assessing the efficiency of management policies for the sustainable use of karstic groundwater in Eastern Europe; and the development of a Decision Support Tool (DST) to implement these policies. The SHETRAN model is physically-based in so far as most of the parameters have some physical meaning. The modifications made to SHETRAN to simulate karstic aquifers are: (1) the coupling of a pipe network model to a variably-saturated 3-d groundwater component (the VSS-NET component), to simulate flow under pressure in saturated conduits; (2) the coupling of surface water features (e.g. sinking streams or "ponors", and spring discharges) to the conduit system; (3) the addition of a preferential "bypass" flow mechanism to represent vertical infiltration through a high conductivity epikarst zone. Lastly, a forward particle tracking routine has been developed to trace the path of hypothetical particles with matrix and pipe flow to springs or other discharge points. This component allows the definition of groundwater protection zones around a source for areas of the catchment (watershed) which are vulnerable to pollution from non-point sources (agriculture and forestry).
