Quantification of morphological changes in river channels and its impact on flood risk 

MORCHFLOOD project conducted a research with the aim to quantify changes in river morphology and its connection with flood risk in detail. This target was implemented through field works (surveys) which took place in selected parts of Bečva (Czech Republic) and Topľa River (Slovak Republic) in the Carpathian region, where morphological changes and flood risk is present. Data obtained during the field works and actual satellite images were used as a base for the development of the present scenario for hydraulic models. A study of historical data was carried out in both rivers and methodology was developed to use these data as a base for various scenarios of river channel geometry. Afterward, these scenarios were used in hydraulic models. The analyses of modeled results and comparison between the rivers with quantification of changes on flood risk were taken place. The project also targeted bringing the outputs into practice with the organization of workshops for water authorities and municipalities occurring in selected river basins and all persons concerned in this phenomena.
