Reservoir sedimentation in the Sebeș hydrographic basin.
Reservoir sedimentation in the Sebeș hydrographic basin.

Summary/Abstract: The hydro-energetic potential assessment of Sebeş River from the Southern Carpathians through the construction of several dams led to the appearance of Oaşa, Tău, Obreja de Căpâlna and Petreşti Reservoirs. The study of quantitative and qualitative characteristics of lake water was the subject of many articles. This study wants to identify the particularities of the lake sedimentation because the sedimentation rate influences the water quality and the lake’s water volume, in fact the electric energy produced in the lake. For this were analysed the sedimentation sources and the indicators of the sedimentation rate, the sedimentation pace, the dynamic of sedimentation process and the characteristic volumes of each reservoir. Using the measurements made, sedimentation areas with maximum development sectors were highlighted. At the end, was analysed the influence of sedimentation process on the lake’s morphometric elements.
