Experimental data are described on the threshold of transport of quartz, ilmenite, and cassiterite grains under oscillatory flow in a flume and the results are compared to those of other investigators. The results show that for a given particle size, critical shear stress (τcrit) increases with increasing wave period and that τcrit increases with both grain size and grain density. These data are compared with prediction equations.
