5.4 Sediment Handling measures: Methods of bed load and suspended load handling in RoR headworks, Design of settling basin (Particle and concentration approach), Estimation of sediment volume in Settling basin, Flushing of deposited sediment, estimation of frequency of flushing
Find out the dimension of a settling basin with turbulence flow for a high head hydropower plant, which utilizes a discharge of 50 m³/sec. The sediment particles coarser than 0.2 mm (w=1.5 cm/sec) have to be trapped in the basin. Draw plan and section showing major components and flushing arrangement. [6+2]
