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 60 m³/s discharge and gross head of 300 m. The sediment particle larger than 0.15 mm (fall velocity=1.5 cm/s) need to be trap in the basin. Consider effect of turbulence as well. [7]
