Bed stability as a parameter describing the hydromorphological balance of a Mountain River

Andrzej Strużyński , Krzysztof Kulesza , Mateusz Strutyński

Abstract

The hydromorphological parameters are used as abiotic descriptors for the classification system introduced by the Water Frame Directive. When studying the eco-literature, authors point out that the introduction of vulnerable species into restored river reach is often not effective as long as the ecosystem has been adapted to the changed river parameters. In fact, as being well-explored, hydromorphological parameters can be successfully used as reference factors of rivers. While bedload granulometry changes reflect the variation of many fluvial processes, bed stability is interpreted here as the key parameter. This first attempt of the evaluation is performed for three selected parts of the Carpathian rivers. The bed stability prognosis for different discharges is done by Armour PC program on the basis of the Gessler method which assumes the probabilistic nature of the bedload movement. The threshold of the bed transportation is given by the critical Shields parameter. The discharges causing bed movement are compared to bankfull and dominant ones as well as to Q10 %, Q25 %, Q50 % and Q75 %.
