摘要: Distribution of velocity flow in compound open channel due to interaction floodplains and main is strongly non-uniform. Defining the distribution an important factor calculation sediment transport estimation discharge. One correction factors discharge shear stress are momentum and energy  coefficients. In this study, effect  and  coefficients on Froude number specific assessed. Stage-discharge relationship was assessed using some empirical formula including Single-Channel Method (SCM), Divided-Channel (DCM), modified divided-channel method (MDCM) compared with together. When only flows all has a same result whereas by increasing covering results them different. The highest value outcome related SCM. Results indicated that considering momentum coefficients have significant energy. Distribution momentum  and  coefficients.  and  coefficients energy.
