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
Design a settling basin for a high head project in a river which utilizes a discharge of 60 m³/s and gross head of 300 m. The sediment particle larger than 0.15 mm having fall velocity=1.5 cm/sec need to be trapped in the basin. Consider the effect of the turbulence and check the length of settling basin using Velikanov's method given correction factor λ=1.5. [8]
