Our fluvial group presented research on Carpatho-Balkan-Dinaric Conference on Geomorphology. The Conference was held from June 24 to 27, 2019 at Szeged in Hungary. It was focused on rapidly changing world, various environmental hazards which cause considerable damages and loss of life, or their consequences change the rate of geomorphological processes and forms in the Carpatho-Balkan-Dinaric Region. We participated in sessions which were focused on problematics linked with human impact on fluvial processes and systems. Our contributions were dealing with Morphological response of mountain streams to long-term human interventions in the Czech Carpathians presented by Tomas Galia, Fluvial system diversity in relation to confluence hydrodynamic zone – a review study by Lukáš Vaverka, Morphological effects of long-term low sediment inputs – the Elbe River by Jan Hradecký, Public perception of gravel bed rivers. A case study from the Czech Carpathians by Zuzana Poledniková, Possibilities for stopping of further degradation gravel-bed Morávka River by Tereza Macurová, and Conceptual framework for restoration of Czech Carpathian Rivers by Václav Škarpich.
