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 dimensions of a continuous flushing settling basin for a high head project in Himalayan River which utilizes a discharge of 60 m³/s and head of 300 m. The sediment particles coarser than 0.15 mm have to be trapped in the basin. Consider the effect of the turbulence and check the length of basin using Valikanov's relation of the density of the silty water of 1.105 ton/m³. Draw plan and section of the basin showing major components. [6+3]
