Evaluation of Regional Sediment Management Actions Using Government Shallow Draft Dredges.

摘要

This Coastal and Hydraulics Engineering Technical Note (CHETN) documents a workshop that evaluated ways to improve Regional Sediment Management (RSM) on projects in the US Army Corps of Engineers (USACE) North Atlantic Division (NAD) and South Atlantic Division (SAD) that use Federal government shallow draft dredges. Government shallow draft dredges operated by US Army Engineer District, Wilmington (SAW) serve multiple projects along the Atlantic Coast. Although operational schedules are regularly coordinated between SAW and user Districts within SAD and NAD, there has been little (if any) technical coordination to use these dredges to promote and achieve more efficient sediment management. In recognition of this, a workshop was conducted 18-19 January 2012 at SAD Headquarters in Atlanta, GA, to provide the opportunity to share shallow draft project specifics and lessons learned across Division lines, to evaluate new ways to use and manage sediment, to improve value (maximize productivity, reduce cost, and optimize across business lines), to gain operational efficiencies, and to determine how to best leverage the capabilities of the government shallow draft dredge fleet. Government shallow draft dredges operated by US Army Engineer District, Wilmington (SAW) serve multiple projects along the Atlantic Coast. Although operational schedules are regularly coordinated between SAW and user Districts within SAD and NAD, there has been little (if any) technical coordination to use these dredges to promote and achieve more efficient sediment management.
