Dustpan dredging is a unique method which has been in use since 1893 and, until recently, exclusive to the U.S. Army Corps of Engineers. The Corps' Marine Design Center is presently involved with the design of a new dustpan dredge, its first new dustpan design since 1934. The application of state-of-the-art technology to this old dredging concept has posed some interesting problems and solutions. This paper presents an overview of the 88-year history of dustpan dredges and discusses in some detail several of their more interesting design aspects, past and present.
