Planning a Full Scale Wave Power Conversion Test 1988-1989
The paper describes the design of the wave power converter and the principal of working. The results from a tank test on a scale model are presented with the main emphasis on design loads...
Double-OWC Wave Power Extractor of a Taut Moored Floating Structure
A double oscillating water column is proposed as a means to improve the efficiency of wave power conversion over a wide range of wave periods in deep water. A mathematical model of the...
Use of Scrap Tires to Harness Wave Energy
A 2.5 meter diameter wave powered pump, fabricated from scrap tires was tested from May 24, 1988 to October 1988 in the Atlantic Ocean at the North Carolina Army Corp of Engineers Waterways...
Estimation of Wave Power as an Energy Resource for Hawaii
One of the most important elements in determining the wave power available by means of a wave power extracting device is the amount of wave energy present at a given location during a...
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...
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...
The U.S. Agency for International Development's Water and Sanitation for Health (WASH) Project: Lessons of the Decade
A review of the International Decade of Water Supply and Sanitation of the 1980's shows the enormous accomplishments made to date: 600 million more people served with a drinkable...
The International Drinking Water Supply and Sanitation Decade and Beyond
The International Drinking Water Supply and Sanitation Decade ends in 1990. Though the Decade has not achieved its numerical objective of universal access to water and sanitation, it has...
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...
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...
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....
International Water Problem on the Rio Grande
Under a 1906 Convention between the Governments of the United States and Mexico, and under the jurisdiction of the International Boundary and Water Commission (IBWC) Mexico receives annually...
Diplomacy and International Environment Issues
This paper examines three current examples of the ongoing diplomatic efforts to deal with selected environmental and water issues that affect our bilateral relationships with Canada and...
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...
