Description Ox-bow lake of the Morava River located nearby the locality of Osypané břehy has undergone significant geomorphological transformation since the cut-off in 2006. Clearly evident is development of two alluvial plugs separating the lake from the active river channel. Maximal depth of alluvial material deposited in the ox-bow lake may reach 4.5 m locally. The slope of concave banks was reduced significantly to the value of 36 degrees; reduction of mean bank slope has reached almost 20 degrees since the cut-off. Vegetation succession began on newly exposed surfaces (alluvial plugs) and on surfaces that are no more disturbed by fluvial processes (steep river banks); prevailing species are willow and poplar.
