The studies consisted of a short pumping test in 16 piezometers and then their flooding and observation of water table recovery after the stopping of the pumping. The test allowed the values of hydraulic conductivity and specific capacity of Muschelkalk layers ranging from 8.56 · 10–8 m/s to 3.63 · 10–3 m/s and from 0.0075 to 128 m3/h/1mS, respectively, to be calculated. The wide range of values is related to the fact of studying the layers characterized by high permeability and water-bearing capacity (Karchowice Beds, Diplopora Beds and Górażdże Beds) as well as layers with low permeability (Gogolin Beds). The dense network of the research points made it possible to demonstrate the surface variability of rocks permeability and water- bearing capacity, determined mostly by the direction of outcrops of individual layers. The results of the conducted studies show that the most water-bearing zone of the area is related to the carbonate rocks of the Karchowice, Diplopora and Górażdże Beds, characterized by the highest values of hydraulic conductivity k (above 2 · 10–4 m/s) and specific capacity q (above 15 m3/h/1mS), in the belt stretching latitudinally through Kosorowice–Otmice. The studied area can be considered a Polish limestone-concrete field where several mines exploiting Muschelkalk carbonate rocks operate. The results of the conducted studies may be useful for the correct prognosis of the groundwater inflow either to already existing quarries or newly designed mines within the Major Groundwater Basins.}, type={Article}, title={Permeability of Muschelkalk rocks (Middle Triassic) of the Krakow–Silesian Monocline in Tarnów Opolski area (South Poland)}, URL={http://www.czasopisma.pan.pl/Content/117031/PDF/w%C4%85sik.pdf}, doi={10.24425/gsm.2020.133934}, keywords={hydrogeological parameters, pumping test, Krakow–Silesian Monocline}, }
