5. Neilsen Method 210378.91 Observed 119607.29 Present Studies: (A)Proposed Equations for Steady State Flow: Present studies describe prediction of sediment inflow based on the published data. The catchment area of the basin is 6271 square kilometer. Width of the river at gauging station is 71.4 m. Empirical equation in mathematical form is proposed based on the data sample of 1312 observations collected over span of 20 years. Fig. 1: Variation of Sediment Concentration and discharge ( Log plot) The Correlation coefficient R² for the equation (10) is 0.958457, which is shown in Fig. 2.
