Risk Analysis for Ship-Bridge Collisions
The authors have developed a propriety software package which has been successfully used to perform risk analyses for several high-level bridge structures across major waterways in coastal...
Beach Erosion Mechanics
Beach erosion along the coasts affects economic, political and conservation conditions. This paper defines the mechanics of the Coriolis Effect, caused by earth spin, along with storm...
The Statistics of Storm-Induced Sediment Resuspension
The passage of a storm increases the wind stress applied to the sea surface. This surface stress is partially dissipated as it is transmitted through the water column. Some fraction of...
Sea Level Rise and Wetland Loss
Increasing concentrations of carbon dioxide and other gases are expected to raise global temperatures several degrees in the next century. Such a global warming could raise sea level a...
Longterm Changes of Tidal Regime in the German Bight (North Sea)
Sea level changes are caused by astronomical tides (periodical changes), meteorological, geological and oceanographical conditions, vertical movements of the earth's crust...
Use of Private Legal Actions to Protect Beaches
In response to shoreline migration, private oceanfront landowners often erect shoreline erosion control structures such as groins and bulkheads. These structures may exacerbate erosion...
Priorities for Federal Marine Pollution Research
To provide guidance for the national marine pollution research and monitoring program, a workshop was held recently to identify and assign priorities to the marine pollution issues facing...
Coastal and Ocean Resources for Energy Development
There has been a growing interest in renewable alternative sources of energy. An increasing effort is being directed towards the problem of extracting energy from the world's...
Improvement and Construction of Coastal Fishing Grounds in Japan
Development of coastal fishery has become one of the most important issue in the field of food supply. Basically, in order to promote coastal fishery, it is necessary to increase marine...
A Preliminary Study on the Comprehensive Exploitation of Coast Zone Resources in the Southern Fujian
The Pacific tidal wave intrudes the South China Sea through the Bass Strait and travels northward as an 'upgoing wave' to Taiwan Strait affecting the Southern...
Beneficial Use of Municipal Sewage in the Ocean
When sewage sludges and effluents are introduced in a properly controlled manner, they can be of benefit to large areas of the ocean. For example, benthic biomass and growth rates of commercially-valuable...
Monitoring Environmental Impacts from Waste Disposal in the Deep Ocean
Deep ocean sites are presently being considered for the permanent disposal of wastes. Their environmental acceptability can only be assessed by an efficient and effective monitoring plan....
Effect of Ocean Setback Standards on the Location of Permanent Structures
A measure of the degree of safety from long-term erosion can be estimated by comparing the actual distance an owner chooses to locate landward of the required setback with the estimated...
Rising Sea Level, Storms, and Coastal Erosion at Ocean City, Maryland
This paper describes the 'greenhouse effect', and its impact on future sea level rise; provides an overview of the possible impacts on Maryland and other coastal...
Rock Masses
Modeling of Underground Openings/Probability of Slope Failure/Fracture of Intact Rock
While soil mechanics has been the dominant interest of Civil Engineers since Karl Terzaghi's recognition of the principle of effective stress, rock mechanics is becoming increasingly...
Engineering Surveying Manual
This manual is directed at the engineering manager who is responsible for planning and executing engineering projects which require the assistance of specialists in engineering surveying....
Staggered Truss Adapted to High Rise
The 34-floor Nashville Convention Center Hotel required a structural system that would overcome the tendency to vibrate in the wind. The solution was a modified staggered frame truss,...
Floating Bridge for 100 Year Storm
In 1979 the west half of the Hood Canal Floating Bridge, built in 1960, in Seattle broke up and sank during a storm that lasted eight hours with winds of 80 mph and gusts over 100 mph....
Building in Space
Work on the nation's first permanently manned space station has begun. Almost $200 million in contracts for conceptual design for the station were awarded by the National...
A Space Age Test Center
The Air Force's Aeropropulsion System Test Facility (ASTF) is the most expensive project the Air Force has ever built. Its massive heaters, coolers and compressors will treat...
