Numerical model calculations have been carried out to investigate the interaction of topography-driven forced and buoyancy-driven free thermal convection in a synthetic, two-dimensional model. Effects of numerous model parameters were systematically studied in order to examine their influence on the Darcy flux, the temperature and the hydraulic head field. It was established that higher geothermal gradients and greater model depths facilitate the evolution of time-dependent free thermal convection in agreement with changes of the thermal Rayleigh number and the modified Péclet number. However, increasing water table slope and anisotropy coefficient favor the formation of stationary forced thermal convection. Free thermal convection mainly affects the deeper part of the midline and the discharge zone of the synthetic model. In the examined model basins, the position of the maximum hydraulic head is located within the bottom thermal boundary layer near the recharge zone. This divergent stagnation point underlies a local downwelling zone characterized by underpressure.

For geothermal exploration, it is crucial to have an insight into the subsurface temperature distribution. A new thermal model of Hungary is presented extending from the surface down to the lithosphere-asthenosphere boundary (LAB) based on a new stochastic thermal modeling workflow. The model solves the heat equation in steady-state, assuming conduction as the main heat transfer mechanism. At the top and the base, we adopt a constant surface temperature and basal heat flow condition. For the calibration of the model, temperature measurements were collected from the Geothermal Database of Hungary. The model is built up in a layered structure, where each layer has its own thermal properties. The prior thermal properties and basal condition of the model are updated through the ensemble smoother with multiple data assimilation technique. The prior model shows a misfit with the observed temperatures, which is explained fundamentally by transient thermal effects and non-conductive heat transfer. Other misfits can be attributed to a-priori assumptions on thermal properties, boundary conditions, and uncertainty in the model geometry. The updated models considerably improve the prior model, showing a better fit with measured records. The updated models are capable to reproduce the thermal effect of lithospheric extension and the sedimentary infill of the Pannonian Basin. Results indicate that the hottest areas below 3 km are linked to the basement highs surrounded by deep subbasins of the Great Hungarian Plain.

The GDRGF concept informs about basin hydraulics and groundwater as a geologic agent. It became obvious that the effect of heterogeneity and anisotropy on the flow pattern could be derived from hydraulic reactions of the aquifer system. The topography and heat as driving forces were examined by numerical simulations of flow and heat transport. Evaluation of groups of springs, in terms of related discharge phenomena and regional chloride distribution, reveals the dominance of topography-driven flow when considering flow and related chemical and temperature patterns. Moreover, heat accumulation beneath the confined part of the system also influences these patterns. The presence of cold, lukewarm and thermal springs and related wetlands, creeks, mineral precipitates, and epigenic and hypogenic caves validates the existence of GDRGF in the system. Vice versa, groups of springs reflect rock–water interaction and advective heat transport and inform about basin hydraulics. Based on these findings, a generalized conceptual GDRGF model is proposed for an unconfined and confined carbonate region. An interface was revealed close to the margin of the unconfined and confined carbonates, determined by the GDRGF and freshwater and basinal fluids involved. The application of this model provides a background to interpret manifestations of flowing groundwater in thick carbonates generally, including porosity enlargement and hydrocarbon and heat accumulation. © 2015, Springer-Verlag Berlin Heidelberg.}, keywords = {Hungary; groundwater flow; Hydraulic properties; Carbonate rocks; Geological agency}, year = {2015}, eissn = {1435-0157}, pages = {1359-1380}, orcid-numbers = {Mádlné Szőnyi, Judit/0000-0002-5628-4386; Tóth, Ádám/0000-0002-7300-6687} } @article{MTMT:3033346, title = {Potentials of transboundary thermal water resources in the western part of the Pannonian basin}, url = {https://m2.mtmt.hu/api/publication/3033346}, author = {Rman, N and Gál, Nóra Edit and Marcin, D and Weibold, J and Schubert, J and Lapanje, A and Rajver, D and Benková, K and Nádor, Annamária}, doi = {10.1016/j.geothermics.2015.01.013}, journal-iso = {GEOTHERMICS}, journal = {GEOTHERMICS}, volume = {55}, unique-id = {3033346}, issn = {0375-6505}, year = {2015}, eissn = {1879-3576}, pages = {88-98} } @book{MTMT:2048748, title = {Geology of Hungary}, url = {https://m2.mtmt.hu/api/publication/2048748}, isbn = {9783642219092}, doi = {10.1007/978-3-642-21910-8}, editor = {Haas, János}, publisher = {Springer Netherlands}, unique-id = {2048748}, year = {2013}, orcid-numbers = {Haas, János/0000-0003-0929-8889} } @article{MTMT:1441814, title = {Lithosphere tectonics and thermo-mechanical properties: An integrated modelling approach for Enhanced Geothermal Systems exploration in Europe}, url = {https://m2.mtmt.hu/api/publication/1441814}, author = {Cloetingh, S and van Wees, JD and Ziegler, PA and Lenkey, László and Beekman, F and Tesauro, M and Förster, A and Norden, B and Kaban, M and Hardebol, N and Bonté, D and Genter, A and Guillou-Frottier, L and Ter, Voorde M and Sokoutis, D and Willingshofer, E and Cornu, T and Worum, G}, doi = {10.1016/j.earscirev.2010.05.003}, journal-iso = {EARTH-SCI REV}, journal = {EARTH-SCIENCE REVIEWS}, volume = {102}, unique-id = {1441814}, issn = {0012-8252}, year = {2010}, eissn = {1872-6828}, pages = {159-206}, orcid-numbers = {Lenkey, László/0000-0003-4236-4075} } @book{MTMT:2947371, title = {Gravitational systems of groundwater flow}, url = {https://m2.mtmt.hu/api/publication/2947371}, isbn = {9780511576546}, author = {Tóth, József}, doi = {10.1017/CBO9780511576546}, publisher = {Cambridge University Press & Assessment}, unique-id = {2947371}, abstract = {This book recognises groundwater flow as a fundamental geologic agent, and presents a wide-ranging and illustrated overview of its history, principles, scientific consequences and practical utilization.

These terranes are composed of different Mesozoic continental and oceanic fragments that were each assembled during a complex Late Jurassic-Cretaceous Palaeogene history. Palaeomagnetic and tectonic data suggest that the Carpathians are built up by two major oroclinal bends. The Alcapa bend has the Meliata oceanic unit, correlated with the Dinaric Vardar ophiolite, in its core. It is composed of the Western Carpathians, Eastern Alps and Southern Alcapa units (Transdanubian Range, Bukk). This terrane finds its continuation in the High Karst margin of the Dinarides. Further elements of the Alcapa terrane are thought to be derived from collided microcontinents: Czorsztyn in the N and a carbonate unit (Tisza?) in the SE. The Tisza-Dacia bend has the Vardar oceanic unit in its core. It is composed of the Bihor and Getic microcontinents. This terrane finds its continuation in the Serbo-Macedonian Massif of the Balkans. The Bihor-Getic microcontinent originally laid east of the Western Carpathians and filled the present Carpathian embayment in the Late Palaeozoic-Early Mesozoic. The Vardar ocean occupied an intermediate position between the Western Carpathian-Austroalpine-Transdanubian-High Karst margin and the Bihor-Getic-Serbo-Macedonian microcontinent. The Vardar and Pindos oceans were opened in the heart of the Mediterranean-Adriatic microcontinent in the Late Permian-Middle Triassic. Vardar subducted by the end of Jurassic, causing the Bihor-Getic-Serbo-Macedonian microcontinent to collide with the internal Dinaric-Western Carpathian margin. An external Penninic-Vahic ocean tract began opening in the Early Jurassic, separating the Austroalpine-Western Carpathian microcontinent (and its fauna) from the European shelf. Further east, the Severin-Ceahlau-Magura also began opening in the Early Jurassic, but final separation of the Bihor-Getic ribbon (and its fauna) from the European shelf did not take place until the late Middle Jurassic. The Alcapa and the Tisza-Dacia were bending during the Albian-Maastrichtian. The two oroclinal bends were finally opposed and pushed into the gates of the Carpathian embayment during the Palaeogene and Neogene. At that time, the main NS shortening in distant Alpine and Hellenic sectors was linked by a broader right-lateral shear zone along the former Vardar suture. (C) 2004 Elsevier B.V.

This perception could not, and did not, evolve until the system nature of basinal groundwater flow and its properties, geometries, and controlling factors became recognized and understood through the 1960s and 1970s. The two fundamental causes for groundwater's active role in nature are its ability to interact with the ambient environment and the systematized spatial distribution of its flow. Interaction and flow occur simultaneously at all scales of space and time, although at correspondingly varying rates and intensities. Thus, effects of groundwater flow are created from the land surface to the greatest depths of the porous parts of the Earth's crust, and from a day's length through geologic times. Three main types of interaction between groundwater and environment are identified in this paper, with several special processes for each one, namely: (1) Chemical interaction, with processes of dissolution, hydration, hydrolysis, oxidation-reduction, attack by acids, chemical precipitation, base exchange, sulfate reduction, concentration, and ultrafiltration or osmosis; (2) Physical interaction, with processes of lubrication and pore-pressure modification; and (3) Kinetic interaction, with the transport processes of water, aqueous and nonaqueous matter, and heat. Owing to the transporting ability and spatial patterns of basinal flow, the effects of interaction are cumulative and distributed according to the geometries of the flow systems. The number and diversity of natural phenomena that are generated by groundwater flow are almost unlimited, due to the fact that the relatively few basic types are modified by some or all of the three components of the hydrogeologic environment: topography, geology, and climate. The six basic groups into which manifestations of groundwater flow have been divided are: (1) Hydrology and hydraulics; (2) Chemistry and mineralogy; (3) Vegetation; (4) Soil and rock mechanics; (5) Geomorphology; and (6) Transport and accumulation. Based on such a diversity of effects and manifestations, it is concluded that groundwater is a general geologic agent.}, year = {1999}, eissn = {1435-0157}, pages = {1-14} } @article{MTMT:2947300, title = {PETROLEUM HYDROGEOLOGY - A POTENTIAL APPLICATION OF GROUNDWATER SCIENCE}, url = {https://m2.mtmt.hu/api/publication/2947300}, author = {Tóth, József}, journal-iso = {J GEOL SOC INDIA}, journal = {JOURNAL OF THE GEOLOGICAL SOCIETY OF INDIA}, volume = {29}, unique-id = {2947300}, issn = {0016-7622}, year = {1987}, eissn = {0974-6889}, pages = {172-179} }
