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 (τ*) • 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 Reference:  ASCE Manuals and Reports on Engineering Practice No. 54: Sedimentation Engineering, Vito A. Vanoni, Editor, New York, NY, 1975. 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.
