Whitaker1,2 and Donald F. Potts1 Received 26 June 2006; revised 28 February 2007; accepted 23 March 2007; published 19 July 2007. [1] Critical shear stress and unit discharge flow competence models were tested against coarse bed load data from Dupuyer Creek, Montana, United States. Maximum particle sizes sampled (Dmax) and D50 to D90 percentiles in the bed load grain size distribution were well correlated with both shear stress and unit discharge. Bed load grain sizes became coarser with increasing flow strength.
