Abrasion Resistance of Polyethylene Dredge Pipe
In recent years there has been a slow but steady increase in the number of dredges using high density polyethylene (HDPE) pipe in discharge lines. HDPE's increased popularity...
Mixed Layer Modelling of Stratification in Lakes
Mathematical models for vertical heat transfer processes in lakes and reservoirs are grouped into two classes: diffusion models and mixed layer models. In recent years much of the progress...
Effects of Fines in Gravel Bed Streams Behavior
A model-gravel bed stream is studied in the laboratory. Flow visualization of bedload motion correlates with bursting phenomena near the bed. The bedload variation as a result of the addition...
Movement of Tractive Sediment from Disturbed Lands
The Smoky Creek basin of the coal area of northeastern Tennessee shows extensive evidence of tractive movement of coarse sediment from mined tributary basins into the main channel. Coal-rich...
River Basin Management: Role of Hydraulics and Hydrology
One of the major Illinois rivers originates in a neighboring state. The main stem of the river was channelized about 65 years ago, and is considered to be a 'drainage ditch....
Optimal Real-Time Operation of a Cascade of Hydropower Plants in Central West China
The Longxihe River hydropower system consists of four hydropower plants in series. The four reservoirs are used for flood control and power generation. Among the four reservoirs, only...
Plastic and Other Limit State Methods for Design Evaluation
These proceedings consist of seven papers dealing with the topic of the design of complex structures using limit state methods. The emphasis is on the role of plastic or limit load techniques....
Structural Engineering in Nuclear Facilities
The papers in this publication cover the general theme of civil and structural engineering as they are applied to nuclear facilities. Traditional topics include seismic analysis, impactive...
Guidelines for Transmission Line Structural Loading
Procedures are provided for the selection of design loads and load factors based on the latest research and state-of-the-art design techniques. This selection has an effort on the reliability...
Building on Air
Copley Place, a $500 million hotel/retail/office/residential complex, was built on air rights over the Massachusetts Turnpike and an adjacent railroad in Boston. Two hotels occupy land...
Geotechnically Allowable Stress for Driven Piles
There are opposing opinions on what value to use for allowable stress in driven steel piles. The key is that two types of stress must be considered: the structurally allowable stress,...
Measurement of Hydrographic Parameters in Large Sand-Bed Streams from Boats
This report concentrates on the state-of-the-art in the field documentation of the existing channel geometry, plus the concurrent stream flow and sediment transport characteristics, prevailing...
Recent Developments in Pavement Skid Resistance
As pavements wear, they lose some of their skid resistance. This article discusses some of the leading options for restoring a pavement's skid resistance. The possibilities...
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...
Seismic Design of Embankments and Caverns
The papers included in this publication were presented at three symposia on seismicity and seismic design for embankment dams and underground openings. Primary topics for discussion include:...
Design for Ice Forces
Part one of this publication on design for ice forces emphasizes offshore and coastal structures. In this section , seasonal ice conditions typical of offshore and coastal zones are reviewed....
Seismic Response of Buried Pipes and Structural Components
At nuclear power plants there are numerous underground safety-related pipes and structural components which are utilized in the operation of the plant. These underground components provide...
West Coast High-Rise Condo Opts for Ductile Concrete Frame
In the past, the vast majority of high-rise buildings constructed in earthquake prone areas of the West Coast have employed a steel frame. However, recent advances have made it feasible...
Design of Port and Coastal Structures for Ice Forces
Design of ice-affected port and coastal structures cannot be addressed in a few single specific terms, but must instead account for a matrix of elements differing at each site. Evaluation...
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...
