Schoklitsch Total Bed Load Formula

Equation for calculate schoklitsch total bed load is,

G_b = (86.7 / D_g^½) × S^3/2 × (Q_i - bq_o)

where,
G_b - total bed load,
D_g - effective grain diameter,
S - slope of energy gradient,
Q_i - total instantaneous discharge,
b - width of river, ft (m),
q_o - critical discharge, of river width (0.00532/S^4/3)D_g
