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.
