In this paper, two formulas were chosen among those that estimate the suspended
sediment discharge in rivers. These two formulas were Lane and Kalinske and Bagnold. For
studying and knowing the correlation between input parameters and calculated suspended
sediment discharge (CSSD), the SPSS17 software was used. Input parameters in these two
formulas were as: water velocity, water discharge, suspended sediment concentration,
hydraulic radius, and depth. By entering input parameters of these formulas into model, the
results of both methods showed no significant correlation between CSSD and input
parameters except water discharge in Lane and Kalinske and water velocity in Bagnold. Other
input parameters have no good correlations with CSSD. Therefore, if Lane and Kalinske
suspended sediment concentration and water discharge multiplied by each other and then
equation powered by 0.5, the correlation between this equation and CSSD become better than
supposing them individually with CSSD.
