online_ackers_white:  Calculation of sediment discharge by the Ackers-White formula   
Formulas:

Q = V D B    •    dgr = d50 [ g (Ss - 1) / ν2 ] 1/3

u* = (g D S )1/2    •    n = 1 - 0.56 log (dgr)

A = [ 0.23 / dgr1/2 ] + 0.14    •    α = 10

Fgr = { u* n / [ g d50 (Ss - 1) ] 1/2 }  { V / [ 321/2 log (α D / d50) ] } 1 - n

m = (6.83 / dgr ) + 1.67    •    C = 10 2.79 log (dgr) - 0.98 [ log (dgr ) ]2 - 3.46

Ggr = C [ ( Fgr / A ) - 1 ] m    •    X = Ggr Ss d50 / [ D (u* / V ) n ]

G = γw Q X
