Inventory of large wood in the Odra River

The upper Odra River upstream Ostrava City represents unique geomorphic meandering pattern on the boundary between the Western Carpathians and Bohemian Massif. During the first week of September, the inventory of instream wood in the protected area of the Odra River took place, where the removal of large wood due to flood risk is prohibited since 2015. In total, 146 individual pieces of large wood were measured and positions of additional large wood jams (several including up to 20 logs) were mapped in ca. 4 km long reach. In addition, 32 large wood pieces were tagged in order to observe their future movement during high water stages. We assume extensive lateral supply of instream wood particularly in active meanders, which was also documented during field mapping.
