The study of river restoration potential of the Černá Ostravice River

Human interactions with mountain streams in Czech part of the flysch Western Carpathians has more than 100 years of history. These are represented by indirect impacts since the 16th century linked with an extensive changes in land use, and by direct human interventions connected with control works, check-dam constructions (e.g., due to timber floating, flood protection, sediment regime control). We finished project which was focused on potential restoration measures in the Černá Ostravice River basin in Moravskoslezské Beskydy Mts in Czech Republic. The project was realized in cooperation with the Union for the Morava River. The study proposes potential measures to improve hydromorphological and habitat conditions in the lower reach of the Černá Ostravice River. The main measures were aimed to increase stream connectivity for aquatic communities or sediment flux, increase morphological heterogeneity and occurrence of instream wood as element affected better stream habitat conditions and increase of water retention in floodplain.
