This thesis discusses the experimental methods used to determine incipient motion conditions and analyses of incipient motion prediction methods. This thesis also presents the experimental results obtained from both test facilities with the results of other published incipient motion studies on gravel streambeds. Finally, the prediction efficiency of eight stone sizing methods (open channel and culvert application) applied to the experimental results was analyzed, which may be useful for determining stable stone diameters to be used as riprap in simulated streambeds through bottomless culverts.2-inch Angular Rock 26 24 22 20 18 16 12 14 10 8 0 2 4 6 4.5 5.0 5.5 6.0 Bed Velocity (ft/s) 6.5 Figure 63. ...
