ABSTRACT. Vertical dynamics of the riverbeds in Cluj and Dej Hills. The study was based on the processing and interpretation of data from five hydrographical stations representative for the investigated region. Analyzing the data from the hydrometric stations on the middle and lower courses of streams Mera, Borşa and Luna is leading us to uncover a trend of moderate or accelerated degradation of the riverbed. The studies implied at the hydrometric station Aghireşu reveal that the riverbed is defined by a relative stability. Instead, the station at Maia shows an almost continuous riverbed sedimentation.
Key words: riverbeds, vertical dynamics, stability, degradation
