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. These simulations draw attention to the importance of understanding the combined effect of forced and free thermal convection in sedimentary basins regarding regional groundwater flow patterns, and temperature distributions.}, keywords = {Finite element numerical modeling; heat transport; topography-driven groundwater flow; thermal buoyancy; forced and free thermal convection}, year = {2019}, eissn = {1879-2707}, pages = {364-379}, orcid-numbers = {Szijártó, Márk/0000-0001-5408-4092; Galsa, Attila/0000-0002-7198-4524; Tóth, Ádám/0000-0002-7300-6687; Mádlné Szőnyi, Judit/0000-0002-5628-4386} } @article{MTMT:3408520, title = {Impacts of predicted climate change on groundwater flow systems: Can wetlands disappear due to recharge reduction?}, url = {https://m2.mtmt.hu/api/publication/3408520}, author = {Trásy-Havril, Tímea and Tóth, Ádám and Molson, JW and Galsa, Attila and Mádlné Szőnyi, Judit}, doi = {10.1016/j.jhydrol.2017.09.020}, journal-iso = {J HYDROL}, journal = {JOURNAL OF HYDROLOGY}, volume = {563}, unique-id = {3408520}, issn = {0022-1694}, abstract = {Climate change can directly influence groundwater systems through modification of recharge. Affecting not only groundwater levels and flow dynamics, climate change can also modify the fragmentation and hierarchy of groundwater flow systems. In this study, the influence of climate change - impacted recharge on groundwater levels and on inter-connected groundwater flow patterns is evaluated. Special emphasis is placed on how flow system hierarchy may change, to examine possible consequences on groundwater-related shallow surface water bodies and on groundwater - surface water interaction. As a test site with no significant anthropogenic impacts, the Tihany Peninsula in Hungary was an ideal area for the study. We address the following issues: i) How might a groundwater system, including groundwater-surface water interaction, be modified by predicted climate change?, ii) Given the variable groundwater levels and flow patterns, how will the water levels and fluxes be impacted around surface water bodies?, and iii) How sensitive are groundwater-related wetlands to these changes, and will they be maintained or will they eventually disappear? In order to answer these questions, two-dimensional transient numerical simulations were performed based on site-specific measurements and climatic prediction at the Tihany Peninsula. Results show that future climate trends can cause dynamic evolution and dissipation of transient groundwater flow systems, and the characteristic flow system hierarchy can change from nested flow systems to a set of single flow cells. Preservation of associated groundwater dependent ecosystems would be challenging under these conditions since long-term climate change could potentially have serious consequences, including wetland disappearance. Understanding these transient processes in two-dimensions can also help to set-up three-dimensional site-specific models. (C) 2017 Elsevier B.V.

At that time the system was fully confined and only the thermal buoyancy influenced the flow of fluids in the system. Parallel with the uplift of the Buda Hills, the infiltration of fresh water into the system began; thus the subsequent evolution of the topography-driven groundwater flow brought about the superposition of the two fluid flow systems. This occurred with different prevailing driving forces: namely, the topography in the upper part and buoyancy in the lower. The uplift of the Gödöllő Hills also had an influence on the processes of the BTK and resulted in the evolution of fluid flow heading from the eastern, confined part of the system towards the River Danube. Consequently, the dominantly basinal fluids of the confining strata infiltrated into the underlying carbonate aquifers filled with meteoric water via vertical leakage. These changes were followed in the mineral paragenesis of the BTK. The western region of the BTK is part of the NE Trans-danubian Range and nowadays the carbonate aquifers are semi- or unconfined. The springs of this area represent the terminal points of local, intermediate and regional flow systems and they display the rock-water interaction along the flow path. The evaluation of the flow pattern could reveal the West–East direction of flow under the River Danube and the upwelling of fluids towards the discharge areas along the River Danube in the upper, shallow part of the system. The NaCl-type basinal fluids originated from the eastern-confining layers and they contribute to the regional flow component. West–Southwest of the River Danube, Mg2+- and SO42 - rich water can be found. The results represent the hydraulically continuous flow sytem of the BTK, the asymmetric flow pattern at the boundary of unconfined and confined carbonate aquifers and, moreover, the significance of confining layers in the accumulation and dissipation of heat. The pressure conditions present in the system are nearly hydrostatic. The NE Marginal Fault also has a role in the differentiation of the discharge areas at the foothills of the Rózsadomb and the Gellért Hill. In the area behind the Gellért Hill an intermediate flow system appears; therefore, at the foothills of the Gellért Hill only thermal water is discharged. At the Rózsadomb the lukewarm and hydrothermal fluid discharge areas are close to each other. Thus the evidence strongly suggests that the respective hydrothermal components of the Central and Southern systems differ. The NaCl-type water of the eastern half of the basin contributes to the discharge of the regional flow path of the Central system. This system transfers H2 S and CH4 to the springs. In the case of the Southern System, the excess of sulphate in the water is more prevalent, and this may be in connection with the evaporite layers in the SW. On the basis of sulphur isotope analysis, the meteoric fluid component of the Rózsadomb receives its sulphur during infiltration through a pyrite-rich covering strata. The brief details mentioned here suggest that a better understanding of the fluid evolution of the BTK will contribute to the interpretation of hypogenic karstification and cave evolution in the area. © 2018, Hungarian Geological Society.

The monitoring network of the thermal karst waters of Budapest consists of 27 sampling locations, from which data for six geochemical parameters and temperature were available for the period 1960-2010. Based on this data, the optimal grouping for the sampling locations was sought using combined cluster and discriminant analysis. Furthermore, the homogeneity of the obtained groups, as well as temporal changes in the overall monitoring system were investigated. The seven groups found are in accordance with the previously established hydrogeological conditions, i.e. the grouping can be considered as optimal. The results obtained using combined cluster and discriminant analysis on the geochemical and temperature database of Budapest have important practical implications, since the thermal waters are an intensely used resource. Any artificial intervention will influence locations belonging to the same group, and therefore the optimal grouping of sampling locations will help in the planning of further activities, This case study might serve as an example in other settings where multiple measurements at multiple sampling locations from a monitoring network are available.

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;
