This report presents the demonstration results of the dustpan dredge Beachbuilder using a flexible discharge at

the Head of Passes/Southwest Pass on the Mississippi River in June 2002. Dustpan dredges equipped with a

flexible-discharge floating hose and sufficient pumping capacity potentially have the mobility required for safe

passage of vessel traffic and can economically pump dredged material the distances required for placement in a

beneficial use scenario such as marsh construction. This report details and discusses the project activities,

operational characteristics of the Beachbuilder, and feasibility of using a flexible-discharge dustpan dredge to

augment the hydraulic dredging capabilities of the U.S. Army Corps of Engineers on the Mississippi and other

rivers. The goal of this report is to use the project results to identify potential opportunities for reducing overall costs

for channel maintenance and increasing beneficial use of dredged materials during dredging Corps navigation

projects.
