'Dredging and Dredged Material Placement' Engineer Manual, the U.S. Army Corps of Engineers New Edition

摘要

The U.S. Army Corps of Engineers (USACE) is currently updating and merging its dredging Engineer Manuals (EMs) into a single document. This new EM, Dredging and Dredged Material Placement, consists of updated versions of the three previous EMs, Dredging & Dredged Material Disposal (EM 1110-2-5025, 1983), Beneficial Uses of Dredged Material (EM 1110-2-5026, 1986), and Confined Disposal of Dredged Material (EM 1110-2-5027, 1987). In addition to these revisions, this document will include a new section on open-water placement. The terms disposal and placement are used synonymously to describe the dredged material deposition after its removal from the dredging prism. This paper provides an overview of this comprehensive document. The new edition describes the dredging equipment and disposal techniques used in the United States, and provides management, engineering, and design guidance for activities associated with new work and maintenance projects. This manual will also provide guidance: 1) on the evaluation and selection of dredging equipment, 2) for planning, designing, constructing, operating, and managing open-water and confined dredged material disposal areas to provide adequate storage volume for both short-term and long-term disposal needs, and 3) for planning, designing, developing, and managing dredged material for beneficial uses, incorporating ecological concepts and engineering designs with biological, economical, and social feasibility. In addition to detailed technical procedures for various design and operations functions, this EM contains numerous citations for the literature, especially peer-reviewed literature, because use of peer-reviewed procedures and methods is critical in gaining credibility and acceptance of designs and evaluations in the regulatory arena. Upon completion, this new EM will be made available on a USACE web site for unlimited distribution.
