online_einstein_brown:  Calculation of sediment discharge by the Einstein-Brown formula   

The Mojave river at Hellendale, California

Formulas:

γw = f (T)

ν = f (T)

γs = Ss γw

τ* = (R S) / [ (Ss - 1)ds ]

φ = f*)

A = [ g ds3 (Ss - 1) ]1/2

B = 36 ν 2 / A2

F1 = [ (2/3) + B ]1/2 - B1/2

gs = φ F1 A γs

Gs = gs W

SI Units (metric):   Hydraulic radius R in m; channel width W in m; bottom slope S in m/m; mean diameter ds in mm; water temperature T in degrees Celsius; Ss is dimensionless.
U.S. Customary Units:   Hydraulic radius R in ft; channel width W in ft; bottom slope S in ft/ft; mean diameter ds in mm; water temperature T in degrees Farenheit; Ss is dimensionless.
