Document Type: Journal Paper


The construction and maintenance of navigation channels through the shallow coastal inlets of North Carolina have always been a hazardous and expensive undertaking. With the development of a shallow-draft sidecasting dredge, the hazards have been virtually eliminated and the construction and maintenance costs have been brought within reasonable limits. The need for a dredge of the shallow-draft sidecasting type is shown and the history of its development is given. The plant is described and the operating procedure in a typical shallow inlet channel is discussed. Performance and cost experience are presented and observations are offered on stability of dredged channels.
