Morphological effects of freshets in section of the Łososina river channel

key words: bank erosion, sediment transport, morphological changes

Summary:

Freshets, by the periodical changes of the hydrodynamic conditions in the river channel, cause its intensive changes. At the time, the occuring fluvial processes have the decisive influence on creation of erosive and cumulative forms in the channel. Dimensions of these forms depend also on sediment transport. This paper presents the results of investigations carried on the Łososina River meander for years 2004–2005. Morphological changes in the channel, created by the 3 freshets, have correlation with the archival data. The bank erosion estimation shows that a cross section of channel has become wider. The changing hydraulic conditions were determined and the sediment transport intensity was estimated.
