online_modified_lane_k1:  Calculation of parameter k1 of the Modified Lane relation   
Formula:

k1 = Qs / [ 58.7 γ Qw So (R / ds)1/3 ]

SI Units (metric):  Qs in M.Tons/day, Qw in m3/s, So in m/m, R in m, and ds in mm.
U.S. Customary Units:  Qs in Tons/day, Qw in ft3/s, So in ft/ft, R in ft, and ds in mm.
