ABSTRACT. – Recent Trends in River Morphodynamics of Turnu Roşu – Călimăneşti Sector. Turnu Roşu-Călimăneşti sector is characterised by a fluvial morphology influenced by numerous conditional factors: lithology, morphometrics and morphology, gradient, sediments, all these creating a transition from the current trends that become apparent in the study of the river morphodynamics. In order to achieve the intended purpose the following objectives were laid down: to improve the methodology of analysis and geomorphological investigation in line with current trends in the field, to highlight aspects of recent morphodynamics, as the study is based on GIS to capture the correlations between the current processes of bed scour and the effects of anthropogenic activities on inland waterway transport sector; to reveal the tendencies of development of riverbeds and slopes. The most obvious human intervention on the river system is the construction of dams (Turnu, Călimăneşti) and the fitting of artificial lakes (Robeşti). Olt River has witnessed important features of this type, with an evolutionary trend.
Keywords: aging, the River Olt, trends, sector, natural units.
