17. Riffle Dimensions Wbkf Bankfull Abkf dbkf Measure Bankfull Width (Wbkf) and Bankfull Area (Abkf) Mean Depth, dbkf = Abkf / Wbkf Width to Depth Ratio, W/d = Wbkf / dbkf

18. W/d = 9.3 / 1.5 = 6.2 Wbkf dbkf Abkf

19. Entrenchment Ratio ER = Wfpa / Wbkf Wfpa = Width of Flood Prone Area measured at the elevation twice bankfull max depth above thalweg Wbkf = Width of Bankfull Channel Wfpa Bankfull 2 x dmax above thalweg dmax Wbkf

20. ER = Wfpa / Wbkf = 63/ 15 = 4.2 Wfpa Wbkf
