The flow mixes with this water and loses density. The velocity can reach 60 mph and is a function of the difference in density between the flow and the water as well as the thickness of the flow. The more material in motion, the thicker the flow, the greater the density difference, and the faster the flow. Sediment and water move from the body of the flow into the head where it diffuses upward and mixes with surrounding water. So long as there is a slope, the flow can continue in a state of autosuspension.
Turbidity currents can even flow uphill but normally follow old channels on the continental slope.
This the classic Bouma Sequence . Formed from dense, thick flows. Liquified Flows Rapidly deposited, loosely compacted sand with open packing and saturated with water can be liquified by a shock or disturbance, especially a tremor. Grains become buoyed by the dispersive stress of the water released from open pores in the sand. Grain impacts aid the dispersion as the water moves upward.
