Abstract:

Fluid mud is a near-bed, high density cohesive sediment suspension layer which is a common cause of estuarial and nearshore sedimentation. It is noted that for a given sediment-fluid mixture, the instantaneous fluid mud layer thickness and the depth below water surface at which this layer is encountered do not depend solely on the vertical concentration profile. An operational definition identifying the depth below which no horizontal mud motion occurs must await further investigation.
