Abstract (in english)
   The Desná River is a left-bank tributary of the Morava R. springing in the highest and most dissected parts of the Hrubý Jeseník Mountains in the Eastern Sudetes. In July 1997, this territory was affected by a flood which resulted from abundant rains lasting four days and which showed in an extreme geomorphic efficiency, leaving behind numerous erosional and depositional destructional landforms. Geomorphological and biogeographical research after the flood was focused on the inventory of these destructional landforms, on the monitoring of their further development and plant succession with regard to physico-geographical properties of the surrounding environment. The research also revealed some destructional landforms of older catastrophic events occurring in the 20th century, namely the disastrous debris flows of 1921 followed by a flood.
   The comparison of destructional landforms from the past floods made it possible to evaluate not only magnitude of the extreme events, but also to assess the frequency of geomorphic processes affected by human intervention into the natural environment of mountains. The research of biota and vegetation in particular demonstrated that floods and slope processes contribute to the colourful mosaic of biotopes, thus conditioning the increased biodiversity of the landscape altered by human activities
