Fig. 2: Variation of Sediment Concentration rate and Discharge It is hyperbolic curve, underestimates the sediment concentration. Therefore the data was re-analyzed and the proposed quadratic equation is: 𝐶 = 0.0005𝑄 2 − 0.2𝑄 + 125 (13) The proposed equation (13) is of second order. It envelops 94 % of the sediment data at one hundred percent band width, it is also seen that 63% of the sediment data at fifty percent band width, which is shown in Fig. 3.
