Flow behavior of sediment-water mixtures in a rotating drum

These experiments report of basal normal stress and fluid pressure, as well as vertical velcity profiles of different sediment-water mixtures in a rotating drum. The experiments were conducted in the vertically rotating drum at Richmond field station of UC Berkeley.
