Abstract
Our present work is meant to discuss the dynamics in sorne cross-sections of severa! rivers situated in different conditions: discharge and load, grain size channel deposits, slope, channel pattern, anthropic intervention. For the short intervals of time characteristics for high floods and season cycles, there has been noticed an alternation of "fill" and "scour" on an amplitude which may go beyond 1-1,5 m. For the longer intervals of time (years) we noticed the alternation of the aggradation and degradation phenomena with a maximal amplitude up to 2-3 m. and even more. We also evaluated the conditions of morphplogical stability of the channels, obtaining exponents of the discharge-at a station with a relatively large space of variation.
