Design Considerations for Wind Loadings
The application of reliability concepts to the treatment of wind loadings on structures has increased in the past several years. Advances have been made in assessing the various uncertainties...
Acid Deposition in the Wind River Mountains
National attention has been focused on the discovery of acidified lakes in the Adirondack Mountains of New York and elsewhere in New England. It is commonly believed that the West, in...
Microcomputer Analysis of Harbor Wind Drift
A microcomputer with general-purpose spreadsheet software was used to analyze wind drift on the water surface of Quincy Bay in Boston Harbor. Wind drift is the movement of the surface...
Structural Safety Studies
Structural engineers are most concerned with the safety aspect of structures. The primary objective of structural engineers is to produce structures which are satisfactory in meeting certain...
Texas Hiplex Experimental Design
Research into rainfall enhancement in Texas expanded rapidly during the 1970's with the Texas HIPLEX program. More recently, the states of Texas and Oklahoma and the United...
Oil Spill Risk Assessment for Marine Vessels
An oil spill risk assessment study should show the estimated relationship between the magnitude of an adverse environmental impact and the probability of equaling or exceeding that impact....
Prior Planning for Post-Hurricane Reconstruction
Planning for hurricane emergencies has focused upon the period immediately before and after the storm's arrival, emphasizing evacuation and disaster relief. Mitigation of...
Managing the Dunes and Wetlands of Norfolk, Va.
The Code of the City of Norfolk was amended in 1982 to establish a procedure for permitting and preservation of the city's saltmarshes and sand dunes. A Wetlands Board was...
Geological Processes and Conservation Management Strategies for Barrier Islands of the Virginia Coast Reserve
A barrier island is a sandy deposit that is located immediately offshore and parallels a mainland coast. It is the principal environment of six interactive environments that make up the...
A Tidal Gauge System in New York Harbor
For over a year, a Real Time Wind and Water Level Telemetry System (RTWLTS or Tidal Gauge System) in New York Harbor has been generating real time data 24 hours per day on actual harbor...
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...
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...
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...
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....
Computational Model for Computing Dune Erosion
This paper summarizes the development of a computer model for determining potential beach and dune erosion along the Florida Panhandle. The results have been used as a guide in delineating...
A Microcomputer Dispersivity Evaluation Method for Thick Aquifers
The Littoral Environment Observation (LEO) program uses volunteer observers recruited to obtain daily visual observations of such coastal variables as breaker height, wave period, direction...
Window Glass in Extreme Winds: Design for Flying Debris
Whether or not to change design procedures for window glass in buildings subject to very high winds was debated at the ASCE Convention in Houston. Preventing gravel and other debris from...
Bridge
Named Outstanding Civil Engineering Achievement of the Year, the Luling-Destrehan Bridge across the Mississippi River, twelve miles north of New Orleans, has a 1,222 ft. main span that...
