Geomorfologické účinky povodně v červenci 1997 na území severní Moravy a Slezka

Year, pages: 2000, 303 - 321

The aim of the article is to bring concise information on geomorphic effects of flood in the north-eastern Czech Republic. The main working method used was interpretation of terrain forms, erosional and accumulated, observed after the flood, interpretation of aerial photographs and reports of other authors. The flood in mountain areas of the Eastern Sudeten and Western Carpathians at the beginning of July 1997 originated in response to long-lasting and intensive rainfall. Its totals along with extraordinary discharges exceeded centennial values in the CzR. Research revealed the development of river channels and valley floodplains in extreme flood events. The majority of channels was widened by side erosion. Severe erosion of floodplain sediments in the upper reaches caused that some rivers returned to the stage of gravel-bed channels and braiding, artificial barriers in the floodplains such as bridges and dikes and a great amount of bed-load, as well as the log jams led, above all in the Sudeten to the origin of barriers and consequently wandering. Comparison of the flood effects showed higher rate of geodynamic processes, above all channel incision in the Western Carpathians. Flood effects were enhanced by anthropic interventions into the floodplain morphology and channels.
