Multilayered Muszyna regional model was constructed in the ArcGIS and the GMS environment. Among the several methods for implementing the model in the GMS system the LPF method was used to create a structure of the model. Conceptual model is a spatial arrangement of the fixed structure, which can be automatically divided in grid blocks of different...

... studied area is located within an open hydrogeologi- cal structure of the common flow system of fresh and medi- cinal waters. The flow conditions of these waters in this structure types have been well recognized in the adjoining catchment area of the Kryniczanka River ( Ciê¿kowski et al., 1999;Witczak et al., 2002). The diagram (Fig. 2) showing the conditions of water flow system was used to construct the numerical ...

... the permeability of this zone is sufficient the gro- undwater supplies the main streams, as shown in the given diagram (Fig. 2). When the permeability is too low, the water table intersects the terrain surface and the flow of water form the spring, which usually initiates small stream. The varied morphology makes the elevated parts, where water table is much higher than in the valleys supplying the deeper water- -bearing zone. Despite the decreasing fracturing ...

... model. These rocks properties applied to the model have been based on the water-pressure tests of the Magura sand- stones (Oszczypko et al., 1981), as well as on the results of pumping test and their interpretation and reinterpretation. These results confirmed that hydraulic conductivity vary with depth according to a preliminary conceptual model (Fig. 2). The variation in the hydraulic conductivity with depth (0-30, 30-100 and 100-200 m below surface) allowed the separation of layers of a hydrogeological model (respec- tively, 2, 3 and 4 - Fig. 6) which are illustrated in the proba- bility plot. The deeper layers of the model are very little re- cognized during the geological ...

The Polish part of the Carpathians is the region in which thermal water potential is still under investigation and exploration, mainly due to complex geological structure and variable hydrogeological settings. Excluding the quite well recognized area of the Podhale artesian basin, the huge area of the so-called Outer Carpathians is poorly recognize...

Charakterystyczną cechą masywu Babiej Góry jest skomplikowany system przepływu wód podziemnych
w ośrodku szczelino-porowym. Złożony system wodonośny wraz z głębokim krążeniem wód podziemnych, uzupełnia morfologa osuwiskowa. Największa ilość wód podziemnych gromadzi się w szczelinach, porach
i oddzielnościach międzyławicowych głęboko spękanego piaskowca magurskiego, a także w przestrzeniach porowych warstw rumoszowych i koluwiów osuwiskowych. Przepływ wód podziemnych w masywie Babiej Góry, jak i ich relacje z wodami powierzchniowymi są uzależnione od wzajemnych powiązań litologii, tektoniki, właściwości hydrogeologicznych skał podłoża (szczelinowatości, porowatości, współczynników filtracji)
oraz ukształtowania powierzchni terenu. Na obszarze badań wydzielone zostały strefy o zróżnicowanych warunkach przepływu wód podziemnych. Model pojęciowy (ang. conceptual model) jest jakościowym opisem systemu obiegu wód podziemnych w powiązaniu z wodami powierzchniowym w modelowanym obiekcie
i stanowi podstawę do jego analizy przy pomocy modeli matematycznych (Kazimierski, 2006). Celem pracy jest przedstawienie modelu pojęciowego systemu krążenia wód podziemnych oraz określenie wzajemnych relacji wód podziemnych i powierzchniowych. Na podstawie tego modelu przedstawionego w formie opisowej i graficznej będzie możliwe w przyszłości opracowanie modelu komputerowego. W ostatnich latach powstało wiele modeli pojęciowych systemu krążenia wód podziemnych przygotowujące modele numeryczne z rejonu fliszu karpackiego m.in. rejonu Muszyny
Numerical modelling is widely spread tool used to estimating of the thermal water resources in geothermal systems. Researchers use this tool for the water thermal formation recognition andfor simulations of environmental processes occurring in geothermal systems during the operating, given the available technical conditions. A choice of appropriate modelling method is determined by specification of research problems. For solving particular problems there was used software dedicated to hydrogeological modelling, with their separate codes/modules. There are comprehensive applications for modelling only geothermal issues, but there is also possibility adapting software and applications from another geological branches. TOUGH simulator (based on the finite difference method-FDM) is dedicated specially to geothermal issues. PHREEQC and related applications are apply for study of chemical composition of the thermal water. For simidating water circulation in geothermal systems and mass/heat transport issues there are used software applications like MODFLOW and SEAWAT (FDM), and FEFLOW or Aqua3D (based on finite element method-FEM). Development of numerical modelling in geothermic is nowadays related with using new algorithms, improving of data editing and processing, cooperation with GIS and creation possibilities for using conceptual modelling.
