Rivers, in their tendency to reach equilibrium profile, undergo a series of permanent changes both in the minor riverbed and in major riverbed. Bâsca Chiojdului riverbed dynamics has a strong impact on riparian and ripicon ecosystems, manifesting both vertically (erosion or clogging) and horizontal (lateral erosion). It is one of the most active rivers in Buzău basin. Erosion intensity is influenced by large changes in the slope of its longitudinal profile. This demonstrates that it is a young water course, which develops in an area with active tectonic and anthropogenic interventions (bottom sills, bridges, lake facilities). The frequency, dynamics and intensity of erosion processes and phenomena affect both the environment and the local communities.
