Experimental Investigation of River Sedimentation

Predictions of total bed material load for investigation of river sedimentation using selected
empirical equations were made based on laboratory data. Data were obtained through
observations made from conducting experiments in the hydraulic laboratory using is mobile
flume and visualization tank.The experiments are categorized under two alignment namely the
straight channel and full curved channel with different discharge. Experimental data covers- flow
discharges of 1.2 l/s, 1.61/s, 2.1511s and 4.11/s, average flow depths of 0.08m and median sediment
sires of 0.25mm. the equations use in the evaluation are Ackers and White, DuBoys, Shield's,
Schoklitsch'% and Meyer Peters's. The selection was based on the performance of these equations
by past investigators who showed good agreement between observed and calculated transport
rates. The accuracy and the reliability of these formulas are verified.
