Open Water Disposal for Marsh Creation James River, VA
There is a need for close cooperation between design and construction of levees on soft foundation for containing dredge material. The scope of this study included marine exploration,...
Implementation of EPA/Corps Site Evaluation Guidance
Past site evaluations have resulted in expensive and time-consuming field studies and a nationwide delay in final designation of interim sites. Recognizing the problem, a joint Corps/EPA...
Fabric-Reinforced Dikes, Craney Island
Three fabric-reinforced test sections 300-, 400-, and 750-ft long were successfully constructed on very soft dredged material deposits within the Craney Island dredged material disposal...
Dredged Material Disposal Modeling - Chesapeake Bay
A plan to deepen the approach channels to Baltimore Harbor from 42 feet to 50 feet involves in part the overboard disposal of about 9. 5 million cubic yards of dredged material in the...
REMOTS Sediment Profiling at the Field Verification Program
Disposal of uncapped highly polluted Black Rock Harbor muds took place in April-May 1983 at a buoy located within the Central Long Island Sound Disposal Area in 62-66 feet of water. Baseline...
Habitat Development Using Dredged Material
Over the past eleven years, a number of environmentally and economically acceptable beneficial uses have been tested and developed using dredged material substrates. This work has primarily...
Surface Runoff Water Quality from Contaminated Dredged Material Placed Upland
Bioassay and associated tests have been developed and are being refined to assist in the evaluation of the environmental impact of dredged material disposal alternatives. Simulated rainfall-surface...
Strip Mine Reclamation Using Dredged Material
This alternative was investigated through the creation of a field study to demonstrate the feasibility of using a cover of dewatered dredged material to reclaim surface mine deposits....
Soil Analysis and Dredging
Analysis of soils before dredging can make or break a dredging project. It is seldom possible to obtain all of the information needed for selecting equipment and estimate outputs. The...
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...
Improved Techniques for Removal of Sediments Contaminated with Hazardous Materials
Realizing the need to improve the capabilities of response personnel in dealing with cleanup operations involving contaminated sediments, the U. S. Coast Guard and the U. S. Environmental...
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...
Plunge Pool Erosion in Cohesive Soils at Two Dams in Kansas
Results of a field study of two plunge pools scoured by horizontal pipe outlets discharging on cohesive channels are analyzed. Formulas for critical tractive shear stress based on plasticity...
Incipient Resuspension of Silt-Clay Sediment
The laboratory study of incipient motion of fine-grained cohesive sediment under oscillatory flow, unidirectional flow and the combined effects of oscillatory and unidirectional flow is...
Hydraulic Testing of a Large Make-Up Pipeline
A 37 mile pipeline which consists of sections of 114 inch, 96 inch and 66 inch pipes was constructed for delivering secondary sewage effluents for power plant makeup. During initial operations,...
Flow and Scour Patterns around Gabion Structures
There is a need for simple, inexpensive and effective means for streambank protection and fish habitat enhancement. Initial results are presented of laboratory research on the performance...
Local Scour at Fish Rocks
There is a growing interest in the enhancement of rearing habitat for juvenile anadromous fish in the Pacific Northwest. This has focused attention on the need for a better understanding...
Modeling Aeration Devices for Glen Canyon Dam
The 41-ft (12. 5-m) diameter tunnel spillways at Glen Canyon Dam experienced major damage during the 1983 spring runoff. This damage was initiated by cavitation. Hydraulic model studies...
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...
Laboratory Studies of Cavitation in Corps of Engineers Hydraulic Structures
A selected bibliography of significant hydraulic laboratory research efforts by the U. S. Army Engineer Waterways Experiment Station to identify the likelihood of and means of preventing...
