The main goal of our study was to identify the effect of external (e.g. climate changes, tectonics) and internal controls (e.g. sediment transport, deposition, vegetation cover) on the evolution of meandering rivers flowing through sedimentary basins using the example of the lower Drava River (Europe, Hungary/Croatia). Field research was conducted along a 50‐km‐long section of the valley. Sedimentary data from boreholes and corings, 35 km of ground‐penetrating radar surveys and analyses of digital maps were conducted to reconstruct channel planform changes. Traces of four meander belts were identified, and 39 AMS radiocarbon dates were used to distinguish the chronology of the fluvial events. The evolution of the lower Drava River comprised alternating periods of deposition (formation of aggrading meander belt) and avulsions. The channel belts were formed owing to upstream sediment delivery and floodplain storage. Changes in climate humidity and the occurrence of high flows influenced the planform of the meanders within particular channel belts. The oldest channel was active at least ~40 000 cal. BP before being reworked by subsequent meanders active between the Late Pleniglacial (30 000–14 700 cal. BP) and Late Glacial (~11 000 cal. BP) periods. The channel belts shifted to the south in the Holocene, between ~11 000 and 250 cal. BP due to the presence of a thrust fault situated diagonally to the Drava Valley. Results show channel width, channel belt width and the surface area of point bar deposits increased in the succeeding generations of meanders and that the style and sedimentary architecture of the channel belts were dominantly dependent on autogenic controls, that is, sediment delivery, aggradation and erosional events (e.g. formation of chute cut‐offs).}, year = {2024}, eissn = {1096-9837}, pages = {642-663}, orcid-numbers = {Słowik, Marcin/0000-0001-8376-3414; Salem, Ali/0000-0001-6176-8345; Kovács, János/0000-0001-7742-5515} } @article{MTMT:34766498, title = {Sediment dredging assessment of the Mrica Banjarnegara hydroelectric reservoir based on technical and economic aspects}, url = {https://m2.mtmt.hu/api/publication/34766498}, author = {Waluyo, G and Laksono, Fx Anjar Tri and Zaenurrohman, J A and Mishra, M and Piranti, A S and Kovács, János}, doi = {10.1080/10402381.2024.2319590}, journal-iso = {LAKE RESERV MANAGE}, journal = {LAKE AND RESERVOIR MANAGEMENT}, unique-id = {34766498}, issn = {1040-2381}, year = {2024}, eissn = {0743-8141}, orcid-numbers = {Laksono, Fx Anjar Tri/0000-0002-6061-6136; Kovács, János/0000-0001-7742-5515} } @CONFERENCE{MTMT:34034552, title = {Frost weathering intensity in relict sand wedges from Hungary inferred from scanning electron microscopy}, url = {https://m2.mtmt.hu/api/publication/34034552}, author = {Farkas, Beáta and Szabó, Péter and Kovács, János and Fábián, Szabolcs Ákos}, booktitle = {6th European Conference on Permafrost: Book of Abstracts}, unique-id = {34034552}, year = {2023}, pages = {434-435}, orcid-numbers = {Farkas, Beáta/0000-0002-7026-8980; Szabó, Péter/0000-0003-0827-3583; Kovács, János/0000-0001-7742-5515; Fábián, Szabolcs Ákos/0000-0001-9127-2113} } @article{MTMT:33777210, title = {Characterization and mapping of MIS‐2 thermal contraction crack polygons in Western Transdanubia, Hungary}, url = {https://m2.mtmt.hu/api/publication/33777210}, author = {Farkas, Beáta and Sipos, György and Bartyik, Tamás and Józsa, Edina and Czigány, Szabolcs and Balogh, Richárd and Varga, Gábor and Kovács, János and Fábián, Szabolcs Ákos}, doi = {10.1002/ppp.2190}, journal-iso = {PERMAFROST PERIGLAC}, journal = {PERMAFROST AND PERIGLACIAL PROCESSES}, volume = {34}, unique-id = {33777210}, issn = {1045-6740}, year = {2023}, pages = {417-427}, orcid-numbers = {Farkas, Beáta/0000-0002-7026-8980; Sipos, György/0000-0001-6224-2361; Czigány, Szabolcs/0000-0002-9158-3162; Kovács, János/0000-0001-7742-5515; Fábián, Szabolcs Ákos/0000-0001-9127-2113} } @inproceedings{MTMT:33884883, title = {Analysis of Tsunami Wave Potential from Gela Nappe Fault Displacement in Southern Sicily, Italy based on Earthquake Focal Mechanism Since 1970}, url = {https://m2.mtmt.hu/api/publication/33884883}, author = {Laksono, Fx Anjar Tri and Kovács, János}, booktitle = {Natural Hazard and Climate Change Conference}, volume = {1}, unique-id = {33884883}, year = {2023}, pages = {22-23}, orcid-numbers = {Laksono, Fx Anjar Tri/0000-0002-6061-6136; Kovács, János/0000-0001-7742-5515} } @CONFERENCE{MTMT:34430959, title = {Historical mine tailings and waste rocks as secondary sources of critical raw materials around the Mecsek Hills, Hungary}, url = {https://m2.mtmt.hu/api/publication/34430959}, author = {Keresztény-Borbás, Eszter and Tóth, Szabolcs and Kovács, János}, booktitle = {Goldschmidt 2023 Conference: abstracts}, doi = {10.7185/gold2023.17924}, unique-id = {34430959}, year = {2023}, orcid-numbers = {Kovács, János/0000-0001-7742-5515} } @article{MTMT:34180795, title = {Comparison of different preparation methods for oxygen isotope determination of phosphate in mammal tooth enamel}, url = {https://m2.mtmt.hu/api/publication/34180795}, author = {Kiss, Gabriella Ilona and Szabó, Péter and Túri, Marianna and Futó, István and Kovács, János and Palcsu, László}, doi = {10.1556/24.2023.00132}, journal-iso = {CENT EUR GEOL}, journal = {CENTRAL EUROPEAN GEOLOGY}, volume = {65}, unique-id = {34180795}, issn = {1788-2281}, abstract = {We tested several sample pre-treatment protocols for the study of oxygen isotope ratios in the phosphate phase of mammalian enamel of ten different fossil samples.

Although sustainable utilisation requires the reinjection of cooled geothermal brine into the host rock, only a fraction of the used water is reinjected in the country. UP sandstone formation is reported to exhibit low injectivity, making reinjection challenging, and its petrophysical properties are poorly known, which increases uncertainty in designing operational parameters. The goal of the study is to provide experimental data and to gain a better understanding of formation characteristics that control injectivity and productivity issues in Upper Pannonian sandstone layers. Petrographical characterisation and petrophysical laboratory experiments are conducted on cores retrieved from two wells drilled in the framework of an R&D project at the depth of between 1750 m and 2000 m. The experiments, such as grain density, porosity, permeability, and ultrasonic velocity, as well as thin section, grain size distribution, XRD, and SEM analyses, are used to determine Petrophysical Rock Types (PRT) that share distinct hydraulic (flow zone indicator, FZI) and petrophysical characteristics. These are used to identify well intervals with lower potential for injectivity issues. The results imply that fines migration due to formation erosion is one of the key processes that must be better understood and controlled in order to mitigate injectivity issues at the study area.
