Erbil, like many other regions, has suffered severe environmental degradation due to urban expansion, vehicular escalation, industrialisation, and substandard fuel usage. This research employs Google Earth Engine, GIS, and Remote Sensing to scrutinise alterations in pollutants (NO2, SO2, CH4, CO, O3, UV) spanning 2018 to 2022. It also incorporates PM2.5 data from Ankawa station (Jan 14, 2023 - May 4, 2023) and land use data (2005-2022) from Modis and Sentinel 2 satellites. The findings reveal a substantial increase in the levels of various pollutants during the specified period. However, in June 2020, most of these levels experienced a decrease due to the coronavirus quarantine measures. For instance, the concentration of NO2 decreased from 0.000256 mol/m2 in 2018 to 0.000166 mol/m2 in 2020. Conversely, by June 2022, the levels had significantly risen to 0.000277 mol/m2. Moreover, among the 107 days record, PM2.5 concentrations reached unhealthy levels on 44 days, while only five exhibited healthy PM2.5 levels. Furthermore, regions at lower sea levels, like Erbil and Khabat, exhibit the highest concentrations of these gases. In contrast, areas at higher sea levels, such as Mergasur and Choman, demonstrate these pollutants’ lowest levels. © 2023 EDP Sciences.

Although these water courses are small, still they have an increasing ecological, touristic and economical role. As maritime sonars are non-ideal tools for shallow waters, the bathymetric survey of these rivers has been taken with cross-sectional methods. Due to recent developments, interferometric surveying technology have also burst into the market of recreational-grade fish-finders. The objective of the current study was the development of a novel, complex and integrated surveying technique which is affordable, robust and applicable even at low water levels. A recreational-grade sonar system was assembled and mounted on a double-hull vessel and connected with a geodetic Global Navigation Satellite System (GNSS) device. We have developed a novel software which enables the bridging between a closed sonar file format and the commonly used Geographic Information System (GIS) datasets. As a result, the several month-long conventional bathymetric survey of the 146 km-long reach of the Drava River was reduced to 20 days and provided channel bathymetry of many orders of magnitude higher than the classical methods. Additionally, a large number of spatial derivatives were generated which enables the analysis of channel morphology, textural variation of channel sediments and the accurate delineation of navigational routes.}, keywords = {Interferometry; bathymetry; sonar measurements; Dráva basin; recreational fishing; active remote sensing}, year = {2020}, eissn = {2220-9964}, pages = {149-170}, orcid-numbers = {Halmai, Ákos/0000-0001-5722-8119; Czigány, Szabolcs/0000-0002-9158-3162; Ficsor, Johanna/0000-0001-9439-516X; Liptay, Zoltán Árpád/0000-0001-8984-9366; Lóczy, Dénes/0000-0002-2542-6775; Pirkhoffer, Ervin/0000-0003-2917-3290} } @inproceedings{MTMT:30688219, title = {A magyarországi kisvízfolyások paleomedervizsgálatának modellezése}, url = {https://m2.mtmt.hu/api/publication/30688219}, author = {Kiss, Kinga and Czigány, Szabolcs and Gradwohl-Valkay, Alexandra Ilona and Marcin, Słowik and Remigiusz, Tritt and Adam, Marciniak and Balogh, Richárd and Dezső, József and Lóczy, Dénes and Halmai, Ákos and Pirkhoffer, Ervin}, booktitle = {Az elmélet és a gyakorlat találkozása a térinformatikában X.: Theory meets practice in GIS}, unique-id = {30688219}, year = {2019}, pages = {147-152}, orcid-numbers = {Czigány, Szabolcs/0000-0002-9158-3162; Lóczy, Dénes/0000-0002-2542-6775; Halmai, Ákos/0000-0001-5722-8119} } @article{MTMT:3320215, title = {Lehetőségek a problémaorientált földrajzoktatás hatékonyságának növelésére a Pécsi Tudományegyetem terepasztala segítségével}, url = {https://m2.mtmt.hu/api/publication/3320215}, author = {Czigány, Szabolcs and Nagyváradi, László and Pirkhoffer, Ervin and Halmai, Ákos and Klimász, Kitti and Kiss, Kinga and M.

Constructivist pedagogy, employing tools of problem and model-based learning, offers new opportunities to meet these challenges. Geomodels, flumes and stream tables may ease the understanding of geographic processes through hand-on-experience for students. With a computer-controlled geomodel, we analyzed the development of 36 high school students’ terminology in the fields of potamology and remote sensing. Potamology terms, provided after the experimental session, were more focused and reflected the information perception and fixation during the experiment. Three weeks later the terminology of the students indicated a partial fixation of the relevant terms. When students’ terminology on remote sensing was analyzed, the pre-experiment terms were loosely connected to the topic. Over the class, students’ terminology increased in the field of potamology. Although it became more topic-specific and focused, students’ remote sensing terminology still contained a large number of off- topic terms by the end of the experiment and three weeks later. Our findings revealed one of the major weaknesses of the Hungarian educational system, i.e. teachers are forced to follow the conventional geographical curricula, therefore hindering their adaptation to cutting-edge educational methods and the learning-by-doing approach of the Western European and North American syllabi.}, year = {2018}, eissn = {1747-7611}, pages = {149-164}, orcid-numbers = {Czigány, Szabolcs/0000-0002-9158-3162; Halmai, Ákos/0000-0001-5722-8119; Lóczy, Dénes/0000-0002-2542-6775; Pirkhoffer, Ervin/0000-0003-2917-3290} }
