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 settling basin for a high head project of Himalayan river which carry a discharge of 30 m³/s and a gross head of 100m. The sediment size to be removed is up to 0.20mm and fall velocity=2 cm/sec. If the turbulence is considered, what will be the dimension of the basin? Check the length of settling basin using Velikanov's method given correction factor λ=1.5. [8]
