Abstract:

An experimental study of wind induced surfacing of fluid mud bottoms in shallow water has been conducted. The experiments involved a channel placed within a wind tunnel, where a two-layered, water-fluid mud stratified system was subject to wind stress effects. Observations and measurements indicated that depending on the Wedderburn number, the interface may either tilt and remain distinct, or erode with subsequent entrainment of the fluid mud particles into the overlaying water. Two circulation cells moving in counter directions where developed within the upper fluid layer. Surfacing of the bottom material occurred primarily at the point where the two cells met, and the location of this point depended on the Richardson number.
