Abstract:

This technical note describes cohesive sediment erosion by the entrainment process, which can be important to the open-water dispersion of fluidized dredged material. Some specific predictive algorithms are presented. Entrainment occurs when a turbulent fluid layer incorporates fluid from an adjacent layer into itself. Entrainment is a fluid process that can be important to cohesive sediment dispersion in the following dredging-related situations during the convective descent phase at disposal just after disposal at the leading edge of a rapid-spreading underflow following disposal if a residual fluid mud layer is formed after fluidization of disposed sediments by waves or other conditions and in navigation channels near agitation or overflow dredging.
