Calculation of sediment discharge by the Modified Lane method, Victor Miguel Ponce, San Diego State University

    online_modified_lane: Calculation of sediment discharge by the Modified Lane relation

Formula:

Q_s = 58.7 k₁ γ Q_w S_o (R/d_s)^1/3

SI Units (metric): Q_s in M.Tons/day, Q_w in m³/s, S_o in m/m, R in m, and d_s in mm.
U.S. Customary Units: Q_s in Tons/day, Q_w in ft³/s, S_o in ft/ft, R in ft, and d_s in mm.
