Fig. 5: Unsteady State Observed and Predicted sedimentation A graph was plotted for the accuracy of predicted with observed and it was found that total data 1312 covered best within ±5% precisely. The calibration is shown in figure number 6. Fig.6: Variation of observed and Predicted data by Equation 18 The computations made for unsteady flow condition, comparison of quantum and the proposed equation are given in table:3. -10.0 0.0 10.0 20.0 30.0 40.0 50.0 60.0 70.0 80.0 10.0 100.0 1000.0 10000.0 Discharge Rate Unsteady Concentration Rate vs Discharge Rate Unsteady c vs Q equation 𝜕 𝑐 𝜕 𝑡 =−5+1.35 ( 𝜕 𝑄 𝜕 𝑥 𝑑 𝑥 𝑑 𝑡 ) 0.96 +( 𝜕 𝑄 𝜕 𝑥 𝑑 𝑥 𝑑 𝑡 ) −0.5 −( 𝜕 𝑄 𝜕 𝑥 𝑑 𝑥 𝑑 𝑡 ) −0.25 0.0 500.0 1000.0 1500.0 2000.0 2500.0 3000.0 3500.0 4000.0 4500.0 5000.0 0.0 500.0 1000.0 1500.0 2000.0 2500.0 3000.0 3500.0 4000.0 4500.0 5000.0 Observed Sediment Concentration Rate Calibration Chart Calibration +_ 5 % envelop Best Fit 430
