online_scour_jainandfisher:  Calculation of local scour using Jain and Fisher's equation    F = v /(gy)1/2 Vc = Ku y1/6D501/3 Fc = Vc /(gy)1/2 For clear-water scour (F - Fc ≤ 0.2): ys = 1.84 a Fc0.25 (y /a)0.3 For live-bed scour (F - Fc > 0.2): ys = 2 a (F - Fc)0.25 (y /a)0.5 [ SI Units (metric):  ys, y and a in m; Ku = 6.19 ] [ U.S. Customary Units:  ys, y and a in ft; Ku = 11.17 ] [ F = Froude number; g = gravitational acceleration ] Extracted from "Sedimentation Engineering," ASCE Manuals and Reports on Engineering Practice No. 110, American Society of Civil Engineers, 2008.
