Carbon Dioxide Release from OTEC Cycles
This paper presents the results of recent measurements of CO2 release from an open-cycle ocean thermal energy conversion (OC-OTEC) experiment. Based...
Reliability Assessment of Wood Components
Considerable progress has been made in the nondestructive evaluation (NDE) of wood components since the introduction of the first concepts more than twenty-five years ago. New stress wave...
Ocean Energy Recovery
This proceeding of the International Conference on Ocean Energy Recovery held in Honolulu, Hawaii from November 28-30, 1989 consists of thirty-eight papers. These papers explore various...
Probabilistic Prediction of Losses to Lifeline Systems Due to Earthquakes
An efficient and practical method for earthquake loss estimation for lifelines is developed, using the recent advances made in the areas of lifeline earthquake engineering and probabilistic...
A Seawall for Sea Mammals
With glass walls only 75 ft from Lake Michigan, an aquarium addition demanded solid seawall protection. Yes, in a strange twist of logic, the first step in creating a whale habitat for...
NDE for Performance of Wood Structures
Significant economic losses result annually due to deterioration and failure of structural wood components. A high percentage of these losses result from our current inability to assess...
Unsteady Aeroelastic Base Moments on a High-Rise Building
To consider aeroelastic instabilities of prismatic structures in winds, i.e., vortex induced vibrations or galloping oscillations, unsteady aeroelastic forces must be investigated as the...
Location of Geologic Discontinuities by Geophysical Techniques
An overview of the seismic refraction method and resistivity methods is given. These two geophysical techniques are integrated into a systematic method for locating geologic discontinuities...
Pile Foundation Construction Practice in Stiff Clays with Dense Granular Layers
A survey was conducted recently in conjunction with a project located in the San Francisco Bay Area to ascertain the general pile driving practice in stiff overconsolidated clays interbedded...
Management of Drumstick Barrier Islands
Three major problem areas exist on these barrier/inlet systems: 1) the updrift inlet which tends to migrate and erode the upland barrier, 2) the narrow, low and sediment-starved downdrift...
Sediment Transport Processes at Sandbridge, VA
Sandbridge Beach is a primarily residential community located along a 7 km reach of narrow barrier beach. Rates of erosion in this area historically have been high, reaching as much as...
The Coastal Breach at Nauset Beach, Chatham, Massachusetts?A Case Study
Nauset Beach, a barrier spit separating Pleasant Bay from the Atlantic Ocean at the town of Chatham, Massachusetts on Cape Cod, breached in a severe storm on January 2, 1987. The breach...
Coastal Barrier Resources Act Report to Congress
The Coastal Barrier Resources Act (CBRA) of 1982 established a system of 186 coastal barriers along the U.S. coasts of the Atlantic Ocean and Gulf of Mexico, and prohibited within this...
The Coastal Management Program in Brazil
As a proposal to guide the rational utilization of coastal resources, the Brazilian government established the National Coastal Zone Management Plan (PNGC), according to the Federal Law...
Low Cost Wave Measurement Program
This paper addresses some problems related to a wave measurement program in the coast emphasizing costs, environmental hazards and technological problems. Subjects covered include coastal...
The Coastline of Rio De Janeiro From a Coastal Engineering Point of View
The Ocean Engineering Department of COPPE/UFRJ started in early 1988 a project called 'Littoral Rio', in order to make an assessment of coastal engineering problems...
Recent Erosion in the Stable Ipanema-Leblon Beach in Rio De Janeiro
This paper presents the findings of a diagnostic study contracted by the City Hall of Rio de Janeiro, concerning beach erosion problems. It first reviews the problem and existing data....
Potential Flow Over a Wavy Bed: A Persistent Error
The standard small-amplitude theory of potential flow over a wavy bed is briefly discussed, together with the three special values of the Froude Number which define four different flow...
Bed Waves Generated by Internal Waves in Alluvial Channels
The flow in an alluvial channel is conceived as a stratified flow both with respect to the velocity- and density-distribution. In such flows internal waves may occur which influence the...
Modelling of Sand Bars in Coastal Environments
A mathematical model describes the formation of sand bars by progressive wind-generated waves. The model decomposes into several constituents linked together in a two step morphological...
