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...
Nonlinear Deformation and Bispectral Change of Random Gravity Waves on Sloping Bed
A WKB-perturbation method is applied to the deformation of random gravity waves in water of slowly varying depth. In the present analysis, a spectral representation of WKB-type is assumed...
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....
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...
Tapping Deep Water Resources
Lena is the first commercial guyed tower. Its jacket is the longest ever fabricated, loaded out and launched in one piece. Lena stands in 1,000 ft deep water and has a three-level oil...
Who Should Design Bridges?
For many years Design-Build-Proposals have been common practice in Europe (except in the UK). Structures in these countries are 20% more economical than similar projects in the U. S.,...
Engineering Education: An Update
ASCE held an engineering education conference in April, 1985, entitled, Educators and Practitioners�Where Are We Going? Participants agreed that a greater interchange is beneficial between...
Effect of Shallow Trench Construction on Cast Iron Pipelines
This paper summarizes the results of three-dimensional finite element analyses to evaluate the strains and displacements sustained by 4, 6, and 8-in. (100, 150, and 200 mm)-diameter cast...
Modeling Failure Probability of Underground Pipes
Factors influencing the performance of underground gas pipes are identified through a literature search and contacts with several utility companies. These factors are categorized as (i),...
Bending Moment of Underground Flexible Pipes in a Centrifuge
The effect of several factors on bending moment of an underground flexible pipe section buried in a ditch with sheet piling was investigated experimentally by means of centrifugal model...
Field Burial Tests of Corrugated Double Wall PVC Pipe
A new lightweight PVC pipe, consisting of a smooth inner wall and a corrugated outer wall, has been introduced in the U. S. sanitary sewer market in 4 through 10 in. diameters. Field burial...
