Flow emanating from perforations in a pipe under a non-cohesive media, such as sand in the coastal environment, can fluidize the overlying media. The fluidized sand can be readily moved to create navigable channels and to aid in sand by-passing at inlets. After 17 years of development, the first full-scale demonstration of the process is in operation. Concurrently, a new series of experiments has been initiated to look at fundamental flow phenomena associated with fluidization in an unbounded domain.
