In general, a high hydraulic gradient is not favoured for MAR implementation, as it causes higher water loss and mixing of recharge water with native groundwater. However, during groundwater-dependent ecosystem (GDE) rehabilitation, these hydraulic gradient-driven flow processes can be taken advantage of. The aim of this research is to test this hypothesis by evaluating the effect of groundwater table inclination, topography, and other local characteristics on MAR efficiency from the perspective of GDE restoration. MAR efficiency was examined from recharge to discharge area in a simple half-basin based on theoretical flow simulations, using GeoStudio SEEP/W software. Different scenarios were compared to analyse the groundwater level increase and the infiltrated water volumes and to assess the efficiency of MAR based on these parameters in each scenario. The theoretical results were applied to a close-to-real situation of Lake Kondor, a GDE of the Danube-Tisza Interfluve (Hungary), which dried up in the past decades due to groundwater decline in the area. Based on the results, initial hydraulic head difference, model length, and hydraulic conductivity are the most critical parameters regarding water level increase at the discharge area. The water amount needed for increasing the water table is mainly influenced by the thickness of the unsaturated zone and the material properties of the aquifer. The findings can help better understand MAR efficiency in light of local groundwater flow processes and contribute to optimising MAR systems. The results of the study suggest that, if water is infiltrated at the local recharge area, the water table will also increase at the corresponding discharge area, which positively effects the connected GDEs. This approach can serve as a nature-based solution (NBS) to sustain sensitive ecosystems in changing climatic conditions.}, year = {2023}, eissn = {2073-4441}, orcid-numbers = {Szijártó, Márk/0000-0001-5408-4092; Tóth, Ádám/0000-0002-7300-6687; Mádlné Szőnyi, Judit/0000-0002-5628-4386} } @article{MTMT:33692577, title = {Multimethodological Revisit of the Surface Water and Groundwater Interaction in the Balaton Highland Region—Implications for the Overlooked Groundwater Component of Lake Balaton, Hungary}, url = {https://m2.mtmt.hu/api/publication/33692577}, author = {Tóth, Ádám and Baják, Petra and Szijártó, Márk and Tiljander, M and Korkka-Niemi, K and Hendriksson, N and Mádlné Szőnyi, Judit}, doi = {10.3390/w15061006}, journal-iso = {WATER-SUI}, journal = {WATER}, volume = {15}, unique-id = {33692577}, abstract = {The hummocky Balaton Highland is located in western Hungary and is part of the Transdanubian Mountains, the most extensive carbonate aquifer system in Hungary. The study region also encompasses Lake Balaton, the biggest lake in central Europe, which is to the south of Balaton Highland. The surface water–groundwater interaction in the Balaton Highland–Lake Balaton region and the groundwater contribution to Lake Balaton are revisited in this paper. Hydrostratigraphic classification was performed first; then, groundwater flow directions by hydraulic head distribution were analysed, and baseflow indices of surface watercourses were calculated. Regarding hydrochemical characterisation, general hydrochemical facies were identified, natural tracers of temperature, chloride and uranium were applied, and the stable isotopic composition of oxygen and hydrogen was determined. Finally, groundwater flow and heat transport were simulated in a 2D numerical model. A high level of hydraulic interaction was evidenced between surface water and groundwater and the sub-regions of Bakony Mountains, Balaton Highland and Lake Balaton by physical and chemical parameters, numerical simulation and groundwater-flow-related natural manifestations, revealing hydraulic continuity in the study region. Based on the results, the division of legislative water bodies can be reconsidered, especially that surface water and groundwater should be regarded as interconnected, and Lake Balaton can be considered a groundwater-dependent ecosystem in any water-use planning in the region.}, year = {2023}, eissn = {2073-4441}, orcid-numbers = {Tóth, Ádám/0000-0002-7300-6687; Baják, Petra/0000-0002-0301-4438; Szijártó, Márk/0000-0001-5408-4092; Mádlné Szőnyi, Judit/0000-0002-5628-4386} } @article{MTMT:33536175, title = {Regional groundwater flow and the future of hydrogeology: evolving concepts and communication}, url = {https://m2.mtmt.hu/api/publication/33536175}, author = {Mádlné Szőnyi, Judit and Batelaan, Okke and Molson, John and Verweij, Hanneke and Jiang, Xiao-Wei and Carrillo-Rivera, José Joel and Tóth, Ádám}, doi = {10.1007/s10040-022-02577-3}, journal-iso = {HYDROGEOL J}, journal = {HYDROGEOLOGY JOURNAL}, volume = {31}, unique-id = {33536175}, issn = {1431-2174}, abstract = {Consideration of regional groundwater flow in aquifer systems allows for solving groundwater issues on a larger scale than single aquifers and contributes to all practical aspects of the UN’s Sustainable Development Goals for water.
