IDENTIFIKACE (DIS)KONEKTIVIT VODNÍCH TOKŮ ZA VYUŽITÍ MAKROGRANULOMETRICKÉ ANALÝZY KORYTOVÝCH SEDIMENTŮ (MORAVSKOSLEZSKÉ BESKYDY)

Roč.17,č.1-2(2010)

Abstrakt

This paper brings evidence on sediment distribution trends in longitudinal profiles of Beskydian high gradient streams. High gradient streams play an important role in the context of fluvial (dis)continuum as they represent a source of sediment for downstream parts of catchments. The main instrument in the identification of river basin (dis)connectivity was grain-size analysis and fluvialgeomorphological mapping. In addition, bedload material transport force was computed for sections in the vicinity of gauging station. The research comprised the study areas of the Býčinec Basin, the Velký Lipový Basin and the Malá Ráztoka Basin.
