River Lock Rehab: A Winter's Tale
Lock & Dam �1 on the Mississippi River between Minneapolis and St. Paul had deteriorated badly but the U.S. Corps of Engineers determined that replacement with a new structure...
River Meandering
The erosion and sedimentation processes associated with river meandering have a profound effect on man's use of rivers and their valleys, as well as the natural environment....
Thalweg Disposal: Demonstration of an Alternative
Disposal of dredged material in the main channel, or thalweg, is an alternative disposal option for maintenance dredging. The material dredged from the Upper Mississippi River is clean...
A Methodology for Open-Water Disposal Site Selection
Pascagoula, Mississippi, is the major industrial region in coastal Mississippi. The existing project, completed in 1965, provides for waterborne transportation from the Gulf of Mexico...
The Need for Training in the Dredging Industry
Training is very important in those cases where the skill of personnel is not adequate to make optimal use of dredging equipment. This holds for management staff as well as for operating...
Design and Construction - Theodore Ship Channel
Environmental impacts, greater technological capabilities, and improved evaluation techniques make the disposal of large quantities of dredge material more complex and involved. Also,...
Selection of Dredged Material Disposal Sites
Federal and state legislation regulating dredging of navigation channels along Maryland's Eastern Shore requires that local governing bodies provide the dredged material disposal...
Mississippi River Fairview Crossing Test
To improve estimates of shoaling rates in the crossings of a deep draft channel from New Orleans to Baton Rouge, a prototype test was conducted in Fairview Crossing at Mile 116 above Head...
Solving Channel Maintenance Problems at Reads Landing, MN
Dredging a sediment trap at the delta of the Chippewa River is being tested as a channel maintenance technique. It's designed to improve the Corps of Engineers predictive...
Ten Years of Long-Term Dredged Material Disposal Planning in the St. Paul District
Long-term dredged material disposal planning for the Upper Mississippi River by the St. Paul District had its beginnings with the Great River Environmental Action Team study (1975-80)....
Long-Term Management of Confined Disposal Areas
Systematic management of confined dredged material disposal sites is becoming increasingly necessary as competition for land use intensifies in regions in which most dredging projects...
Capped In-Water Disposal of Contaminated Dredged Material
The Seattle District and the Corps of Engineers Waterways Experiment Station (WES), Vicksburg, Mississippi, are cooperating in a field demonstration study to evaluate the effectiveness...
Settling of Dredged Material Slurries
Most environmental engineers, accustomed to dealing with clarification of suspensions containing approximately 150 mg/1, find it difficult to comprehend dredged material slurries, in which...
A New Laser Range/Azimuth Position Fixing System
The ATLAS POLARFIX is an entirely new dynamic position-fixing system for short-range, large scale surveys. It is a range/azimuth laser-based system using only a single shore-based tracking...
Sediment Resuspension from Dredging Activities
Dredges are a logical choice for removing contaminated sediments from our Nation's waterways. Historically, the dredging industry has emphasized increased production in an...
The Corps' Environmental Effects of Dredging Programs
The major programs addressing environmental effects of dredging and disposal that have been or are being conducted by the Corps since 1973 are: Dredged Material Research Program, Dredging...
Dredging-Related Considerations in Navigation Channel Design
In the design of a navigation project, the channel depth, width, and alignment for a given set of navigation requirements are dependent on physical, hydrodynamic, and sedimentological...
Numerical Flood Routing for Natural Channels
A numerical model has been developed for simulating the propagation of a flood wave in a natural channel. Using this numerical model, the influence of the factors affecting the motion...
