Funding Information: We would like to thank Dr Maria Kämäri, MSc Franziska Wolff, MSc Mariana Verdonen, MSc Tiia Tarsa and MSc Marko Kärkkäinen from the University of Eastern Finland, William Speirs from the University of Queensland (Brisbane, Australia), Dr Carlos Gonzales-Inca and MSc Jouni Salmela from the University of Turku and Dr Nikita Tananaev (Melnikov Permafrost Institute [MPI] at Yakutsk, Russia) for their valuable fieldwork assistance in 2016–2021. We also thank Marko Kärkkäinen for analysing the bedload transport amounts and grain sizes and processing the orthomosaic image from the aerial photos of February 2021. It would not have been possible to conduct the fieldwork without the drilling assistance of Ilkka Syvänperä and Esa Karpoff from the Kevo Subarctic Research Institute of University of Turku during 2016–2021. The authors have no conflicts of interest to declare. The ice-covered flow measurements were initiated under the post-doctoral research project of Dr Lotsari, funded by the Academy of Finland (ExRIVER: grant number 267345). The work for this paper was also supported financially by four other Academy of Finland funded projects (DefrostingRivers: 338480; HYDRO-RDI-Network: 337394 and 337279; InfraRiver: 296090; Green-Digi-Basin 347701). Funding was received from the Maj and Tor Nessling Foundation (ExRIVER, grant numbers: 201300067 and 201500046; Influence of river ice and fluvial processes on river environments now and in the future, grant number: 201600042) and Strategic Research Council at the Academy of Finland (Competence-Based Growth Through Integrated Disruptive Technologies of 3D Digitalization, RobotiCS, Geospatial Information and Image Processing/Computing – Point Cloud Ecosystem, grant number: 293389). The Department of Geographical and Historical Studies, University of Eastern Finland, supported the work financially. Funding was also received from the British Society for Geomorphology (research project title ʻDefrosting sedimentary systems: the impacts on the evolution and ...
