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...
Riprap Sizing-Four Methods
A comparison summary is provided for sizing of riprap by four methods: Isbash, Froude, Tractive Force - Logarithmic Velocity Profile (TFL), and Tractive Force - Power Velocity Profile...
Prototype Studies of Corps of Engineers Structures Experiencing Cavitation Damage
A number of Corps of Engineers structures have sustained damage caused by the occurrence of cavitation. The damage has varied from slight pitting to severe erosion. The damage has occurred...
Nebraska's Shrinking Platte River Channel: Biological Aspects and Implications
Since the completion of major water projects along Nebraska's Platte River system in 1941, vegetative encroachment and channel narrowing have substantially altered the central...
Nebraska's Shrinking Platte River Channel: Hydrologic Aspects and Implications
Biologists have proposed two hypotheses to explain recent channel narrowing and vegetative growth in flood plain habitat areas along the Platte River in Nebraska. One group contends, without...
Current Research in Hydraulics at the Corps of Engineers Waterways Experiment Station
Ongoing activities in hydraulics research at the U. S. Army Engineer Waterways Experiment Station are described. The various areas in which research is under way are enumerated. Activities...
Dredging and Dredged Material Disposal
Waterborne commerce is a major factor in the economy of many countries. Because waterborne commerce depends on the ability of nations to provide adequate navigation channels to transport...
Flood Routing on a Small Computer
A BASIC program is developed to route flood discharge through a system of river channels and reservoirs. The brevity of this program and the use of an overlaid computational matrix make...
Ditch Flow Program
Seventeenth in the CE Computing BASICS series, the program in this article is for simplifying drainage calculations. The program will provide critical and normal velocities, depths and...
Design of Ships for Ice Environments
A number of feasibility studies have proven the reliability of marine transportation for the Arctic. Current research and development in this field, especially in the USA and Canada, is...
River and Lake Ice Processes Relevant to Ice Loads
Ice effects on engineering structures in inland waters are more widespread than generally appreciated. Troublesome ice conditions can be expected regularly north of the 0 degree C January...
Design of Navigational Structures for Ice Forces
An overview of ice conditions and the types of ice action that are hazardous to navigational structures is presented. Depending on the circumstances, ice failure against structures occurs...
Record Concrete Box Girder Spans Houston Ship Channel
The Houston Ship Channel Bridge is an American advancement of the cast in place, post-tensioned, segmentally constructed, concrete box girder design. In spite of the complex and unique...
Journal of Waterway, Port, Coastal, and Ocean Engineering
The Journal of Waterway, Port, Coastal, and Ocean Engineering presents information regarding the engineering aspects of dredging, floods, ice, pollution, sediment transport, and tidal wave action that...
Surveying and Photogrammetry Research Needs
