Mathematical Modeling of River Ice Process
Computer modeling of flow and ice conditions in a river is an important element in the planning of water resources project in northern regions. River ice processes are closely related...
Modeling Intake Performance Under Frazil Ice Conditions
A water intake was modeled in a refrigerated flume in an active frazil icing environment in order to evaluate alternative modifications to the prototype structure. Tests were run until...
Reduction of Intake Flow Due to Ice Rubbling and Consolidation
Numerous seawater intakes have been designed for Arctic Coastal Waters. In these areas moving ice often causes rubbling and pile up of broken ice pieces against the shore. If this forms...
The Importance of Nonlinear Wave Interactions Under Ice
Waves under ice interact at the second order in wave slope. Because of this, a monochromatic wave train impinging on an ice sheet can transfer a significant amount of energy to its own...
Hydraulics of Freeze-up
A classification scheme for freeze-up of a river is proposed based upon the response of indicated stage. A conceptual model is developed to describe the course of the indicated responses....
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...
Characterization of Offshore and Coastal Ice Conditions
Seasonal sea ice conditions typical of nearshore coastal zones are reviewed. Prominent ice features influencing design ice conditions for offshore structures are described. This paper...
