These floods have significantly shaped the catchments of small streams in the Mecsek Hills and some rural areas over the past two decades. However, there has been no previous study examining the hydromorphology of headwater catchments in low mountain environments in Hungary. The present study was meant to investigate the fundamental hydrogeomorphological properties of a first-order catchment. A customary and detailed GIS survey of 50-metre sections was aimed at deciphering flash flood vulnerability and geomorphic interrelations within a micro watershed. We found moderate susceptibility to flash floods compared to the whole Mecsek Hills. Stable large woody debris jams were identified during the field survey as major geomorphic channel features functioning as natural barriers which drive channel evolution and reduce flood hazards.}, year = {2023}, eissn = {2064-5147}, pages = {365-381}, orcid-numbers = {Lóczy, Dénes/0000-0002-2542-6775; Fábián, Szabolcs Ákos/0000-0001-9127-2113} } @article{MTMT:34041452, title = {In memoriam Ferenc Schweitzer (1939–2023)}, url = {https://m2.mtmt.hu/api/publication/34041452}, author = {Fábián, Szabolcs Ákos and Varga, Gábor and Lóczy, Dénes}, journal-iso = {HUNG GEOGR BULL (2009-)}, journal = {HUNGARIAN GEOGRAPHICAL BULLETIN (2009-)}, volume = {72}, unique-id = {34041452}, issn = {2064-5031}, year = {2023}, eissn = {2064-5147}, pages = {201-202}, orcid-numbers = {Fábián, Szabolcs Ákos/0000-0001-9127-2113; Lóczy, Dénes/0000-0002-2542-6775} } @{MTMT:33829547, title = {A Rihmer féle pécsi mamut (Mammuthus primigenius) – A „Pécsi mamut” napjainkban – számvetés a JPM Természettudományi Osztályán őrzött mamutleletről}, url = {https://m2.mtmt.hu/api/publication/33829547}, author = {Varga, Gábor and Kisbenedek, Tibor and Markovics, Bernadett and Varga, Ágnes}, booktitle = {LAUS PANNONIAE Kutatások a Janus Pannonius Múzeumban}, unique-id = {33829547}, year = {2023}, pages = {26-27} } @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} } @article{MTMT:33202808, title = {Generation of a flood susceptibility map of evenly weighted conditioning factors for Hungary}, url = {https://m2.mtmt.hu/api/publication/33202808}, author = {Sarkadi, Noémi and Pirkhoffer, Ervin and Lóczy, Dénes and Balatonyi, László and Geresdi, István and Fábián, Szabolcs Ákos and Varga, Gábor and Balogh, Richárd and Gradwohl-Valkay, Alexandra Ilona and Halmai, Ákos and Czigány, Szabolcs}, doi = {10.5937/gp26-38969}, journal-iso = {GEOGRAPHICA PANNONICA}, journal = {GEOGRAPHICA PANNONICA}, volume = {26}, unique-id = {33202808}, issn = {0354-8724}, abstract = {Over the past decades, in the mountainous, hilly and/or urban areas of Hungary several high-intensity storms were followed by severe flash flooding and other hydrologic consequences. The overall aim of this paper was to upgrade the national flash flood susceptibility map of Hungary first published by Czigány et al. (2011). One elementary watershed level (FFSIws) and three settlement level flash flood susceptibility maps (FFSIs) were constructed using 13 environmental factors that influence flash flood generation. FFSI maps were verified by 2,677 documented flash flood events. In total, 5,458 watersheds were delineated. Almost exactly 10% of all delineated watersheds were included into the category of extreme susceptibility. While the number of the mean-based FFSIs demonstrated a normal quasi-Gaussian distribution with very low percentages in the quintile of low and extreme categories, the maximum-based FFSIs overemphasized the proportion of settlements of high and extreme susceptibility. These two categories combined accounted for more than 50% of all settlements. The highest accuracy at 59.02% for class 5 (highest susceptibility) was found for the majority based FFSIs. The current map has been improved compared to the former one in terms of (i) a higher number of conditional factors considered, (ii) higher resolution, (iii) being settlement-based and (iv) a higher number of events used for verification.}, year = {2022}, eissn = {1820-7138}, pages = {200-214}, orcid-numbers = {Sarkadi, Noémi/0000-0002-2370-8621; Pirkhoffer, Ervin/0000-0003-2917-3290; Lóczy, Dénes/0000-0002-2542-6775; Balatonyi, László/0000-0001-5130-730X; Geresdi, István/0000-0002-3160-7900; Fábián, Szabolcs Ákos/0000-0001-9127-2113; Halmai, Ákos/0000-0001-5722-8119; Czigány, Szabolcs/0000-0002-9158-3162} } @article{MTMT:33042768, title = {Morphometric analysis of low mountains for mapping flash flood susceptibility in headwaters}, url = {https://m2.mtmt.hu/api/publication/33042768}, author = {Víg, Balázs and Fábián, Szabolcs Ákos and Czigány, Szabolcs and Pirkhoffer, Ervin and Halmai, Ákos and Kovács, István Péter and Varga, Gábor and Dezső, József and Nagy, Gábor and Lóczy, Dénes}, doi = {10.1007/s11069-022-05513-6}, journal-iso = {NAT HAZARDS}, journal = {NATURAL HAZARDS}, volume = {114}, unique-id = {33042768}, issn = {0921-030X}, abstract = {Morphometric indices from high-resolution DEMs can contribute to the estimation of flash flood susceptibility in mountainous areas. We have screened 25 morphometric indices commonly used in literature, and based on a correlation matrix, selected those which showed the strongest relationship with flash flood generation: area ( A ), drainage texture (Rt), drainage density (Dd), elongation ratio (Re), form factor (Ff), lemniscate method ( k ), Gravelius coefficient (GC), forested area (Fa) and relief ratio (Rr). Among them Dd, Rt and Rr had a direct impact on flash flood generation, while A , Re, Fa, Ff, k and GC are in inverse relationship with the intensity of flash floods. Our summary map shows the prioritization of the watersheds on a scale of 0 to 9. The flash flood susceptibility ranking was empirically verified using hydrological data (20-year water regime obtained from 14 official stream gauges). Our conclusions only partially agree with former observations which may be explained by the particular lithology and morphology of the Mecsek Mountains. Since the lower sections of the watersheds are urbanized, for optimal watershed management more detailed GIS analyses of anthropogenic controls on flash flood hazard are needed in the future.}, keywords = {Runoff; Mecsek Mountains; compactness; Morphometric indices; Flash flood susceptibility; Watershed prioritization}, year = {2022}, eissn = {1573-0840}, pages = {3235-3554}, orcid-numbers = {Fábián, Szabolcs Ákos/0000-0001-9127-2113; Czigány, Szabolcs/0000-0002-9158-3162; Pirkhoffer, Ervin/0000-0003-2917-3290; Halmai, Ákos/0000-0001-5722-8119; Kovács, István Péter/0000-0002-0270-4365; Lóczy, Dénes/0000-0002-2542-6775} } @article{MTMT:32581403, title = {A MOHÁCSI TERASZOS SÍK DOMBORZATI ÉS VÍZRAJZI VISZONYAI, VALAMINT EZEK SZEREPE A MOHÁCSI CSATA HELYÉNEK PONTOSÍTÁSÁBAN}, url = {https://m2.mtmt.hu/api/publication/32581403}, author = {Gyenizse, Péter and Lóczy, Dénes and Varga, Gábor and Pap, Norbert and Kitanics, Máté and Szalai, Gábor and Morva, Tamás and Németh, Gergő}, journal-iso = {TÖRTÉNETI FÖLDRAJZI KÖZLEMÉNYEK}, journal = {TÖRTÉNETI FÖLDRAJZI KÖZLEMÉNYEK}, volume = {9}, unique-id = {32581403}, issn = {2064-390X}, year = {2021}, pages = {57-74}, orcid-numbers = {Gyenizse, Péter/0000-0002-8175-9734; Lóczy, Dénes/0000-0002-2542-6775; Pap, Norbert/0000-0001-8243-4213; Kitanics, Máté/0000-0003-0073-7451; Szalai, Gábor/0000-0002-8039-8447; Németh, Gergő/0000-0001-7833-4017} } @inbook{MTMT:32115149, title = {Horgásztavak elérhetőségének vizsgálata Baranya megyében}, url = {https://m2.mtmt.hu/api/publication/32115149}, author = {Nagy, Gábor and Czigány, Szabolcs and Gyenizse, Péter and Nagyváradi, László and Pirkhoffer, Ervin and Varga, Gábor}, booktitle = {„Szubjektív élményföldrajz” : Tanulmánykötet Aubert Antal professzor tiszteletére}, unique-id = {32115149}, year = {2021}, pages = {183-195}, orcid-numbers = {Czigány, Szabolcs/0000-0002-9158-3162; Gyenizse, Péter/0000-0002-8175-9734} } @{MTMT:32098483, title = {Cseppnyi víz a sivatagban}, url = {https://m2.mtmt.hu/api/publication/32098483}, author = {Geresdi, István and Varga, Gábor}, booktitle = {A hét kristály rejtélye - galaktikus geográfia}, unique-id = {32098483}, year = {2021}, pages = {56-83}, orcid-numbers = {Geresdi, István/0000-0002-3160-7900} } @inbook{MTMT:31672843, title = {A Mohácsi-sík és környéke geomorfológiai viszonyai, valamint ezek szerepe a mohácsi csatában.}, url = {https://m2.mtmt.hu/api/publication/31672843}, author = {Gyenizse, Péter and Varga, Gábor}, booktitle = {Mordortól Mohácsig}, unique-id = {31672843}, year = {2020}, pages = {23-50}, orcid-numbers = {Gyenizse, Péter/0000-0002-8175-9734} }
