Özet:

Settling basins are the hydraulic structures used to get sediment-free water from rivers mostly for hydropower systems. Mainly fine sediment is trapped along the settling basins and from time to time the accumulated sediment in the settling basin is flushed away. A wrong design of a settling basin creates lots of problems. In this study based on the hydraulic analysis of a settling basin, the available settling basin design procedures in the literature were reviewed. Some of the settling basins constructed in Turkey were studied and the problems observed in their operations were analyzed. In an experimental setup a series of experiments were conducted at the laboratory with two types of sediments, quartz and silisium , at various size ranges to determine their maximum settling distances as a function of sill height of the model. The related parameters were presented graphically in dimensionless forms.
