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...
Cavitation in Various Types of Shear Flow
Cavitation in turbulent shear flow depends on the intensity and spectral characteristics of the pressure fluctuations in a Lagrangian frame of reference as well as depending on the concentration...
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...
Factory-Built Pump Stations for Water Service
Booster pumps for fire protection in tall buildings and small sewage pump stations have been available for many years as factory-built packages. These packages include pumps, motors, controls,...
Recreational Freshwater Embayment Design for Acceptable Water Quality
Combined field and laboratory studies were used to relate water quality, geometry, and exchange characteristics in reservoir swim embayments. Water surface fluctuations in reservoirs are...
Water Resources at the Utah Water Research Laboratory
The research staff comes from a wide spectrum of water science and engineering specialties. The authors address such diverse topics as hydraulic testing, erosion studies, and water quality...
Lifeline Earthquake Engineering
Performance, Design and Construction
Lifeline Earthquake Engineering: Performance, Design and Construction is a follow-up publication to the Technical Council on Lifeline Earthquake Engineering publication Advisory Notes...
Sedimentation Consolidation Models?Predictions and Validation
In very soft sediments, questions have arisen concerning the capability of standard computational techniques used to implement calculations. The problems mainly lie in the manner in which...
Guidelines for the Seismic Design of Oil and Gas Pipeline Systems
Current knowledge on the practice of earthquake engineering for oil and gas pipeline systems is presented. Such systems typically consist of buried oil, gas, or product pipelines and aboveground...
Asphalt: Great Expectations
A $50 million, five year research program has been proposed for research into asphalt as part of the larger ($150 million) Strategic Transportation Research Study (STRS). The research...
Ports 83
The Ports '83 Specialty Conference, whose theme is Modernization, Upgrading and Repairs, covers considerations in port operations, design and construction due to obsolescence...
Coastal Structures '83
The objective of the conference Coastal Structures '83 was to develop in-depth discussion of the state-of-the-art and future needs concerning coastal structures. Design, construction,...
Lightweight Fill Helps Albany Port Expand
Lightweight aggregate was used as a soil fill in the reclamation of a marine terminal at the Port of Albany, New York in order to stabilize the dockside area. Gravel-filled steel sheet...
