Figure 10. (Top left) Typical bed shear stress distribution prediction after formation ofelevation wave (note change in sign due to flow reversal). (Top right) Corresponding flowvelocity prediction. (Bottom) Maximum bed stress prediction as a function of range. A bedstress ~ 2N/m 2 would lift sand type particles with diameter < ~0.1mm (Shields criterion [13]).16
