Description :
This paper presents a complex analysis of both the contemporary and the historic development of the geomorphic regime of the transformed reach of the Morávka River in the Czech Carpathians. The assessment concentrates on the conditions and causes of the channel development in the last c. 200 years compared with the state of European channels, especially those of the Carpathian zone. The Morávka River pattern has undergone a rapid change in the last 50 years, particularly in connection with the active channel narrowing and massive incision. The original anabranching river pattern has gradually been replaced by a simple, narrowed channel incised into the bedrock. These changes have been caused by strong anthropogenic impacts in the form of the river-channel control, bank stabilisation, and weir and valley dam construction. Other reasons are related to land cover and land-use changes, and also to the geological predisposition of the Carpathian flysch lithology in channel bedrock.
