Quantitative computation of sediment discharge in alluvial channels is conducted by the determined method based on the incipient motion or the sediment transport concept. The derived formulation of sediment concentration in this study was developed in order to compute the total sediment discharge by a regression analysis method, one of the determined methods by the sediment transport concept. The used data set in derived formulation consists of the total 360 data including 135 and 225 measured data in natural channels and experimental channels, respectively. Also, the formulation by the multiple regression analysis was composed of independent bariables of flow depth, mean velocity, channel slope, Froude number and median diameter in bed materials.
