Abstract: For rivers in flood and beaches under wave attack, the shear stress at the top of the stationary granular bed can set up a sheared layer of contact‐load (bed‐load) particles. This type of motion also occurs in pressurized ...

Abstract: Experiments involving bed forms have usually been carried out in flumes, but in the present work a pressurized-conduit system was found to be appropriate for investigating sediment motion at high shear stress. The bed ...
