Abstract: Since the end of 19th century artesian confined groundwater has played a primary role for the rural potable water supply in Eastern Styria (Austria) because this groundwater is well protected against antropogenic influences by impermeable layers. In order to get planning documents for the management of these groundwater numerous investigations, based on geological, geophysical, hydrological and hydraulic data, were executed. By means of this data and by the analysis and interpretation of the piezometric level hydrograph of the surveying places we have tried to simulate the groundwater flow. The recorded piezometric level hydrograph made it possible to predicate on the distribution of the storage coefficient in the investigation area by way of the calculation of the barometric efficiency. The available data permitted only the creation of two-dimensional flow models. The model of the Safe Valley affirms the assumption that the horizons covered in the investigation area represent a multiaquifer and that there doesn' t exist a direct hydraulic connection between the different horizons. In the Feistritz Valley a single horizon could be defined by pumping tests. For this horizon the simulation of the steady contribution was executed.
