Surveying's New Promise: Centimeters from Space
One centimeter accuracy at far less cost than surveying by traditional methods is promised by the Global Positioning System (GPS). Signals from NAVSTAR satellites are received by two or...
Selection of Dredged Material Disposal Sites
Federal and state legislation regulating dredging of navigation channels along Maryland's Eastern Shore requires that local governing bodies provide the dredged material disposal...
A New Laser Range/Azimuth Position Fixing System
The ATLAS POLARFIX is an entirely new dynamic position-fixing system for short-range, large scale surveys. It is a range/azimuth laser-based system using only a single shore-based tracking...
Dredging-Related Considerations in Navigation Channel Design
In the design of a navigation project, the channel depth, width, and alignment for a given set of navigation requirements are dependent on physical, hydrodynamic, and sedimentological...
Design of Navigational Structures for Ice Forces
An overview of ice conditions and the types of ice action that are hazardous to navigational structures is presented. Depending on the circumstances, ice failure against structures occurs...
Surveying and Photogrammetry Research Needs
An ASCE-National Science Foundation committee listed and prioritized research needs in surveying and photogrammetry. Among them are the Department of Defense's Global Positioning...
Preventing Another Sunshine Skyway Bridge Disaster
America will not soon forget the tragic collapse of the Sunshine Skyway Bridge into Tampa Bay almost two years ago. That accident was a costly lesson in the crucial importance of protecting...
Water Forum '81
One hundred seventy-one papers that were part of the American Society of Civil Engineer's 1981 specialty conference on water issues are included. The publication is presented...
Thames River Flood Barrier
For 200 years, flood tides have surged into the Thames flooding London and its vicinity. Ground subsidence in the area and the melting of the polar ice cap is combining to worsen the problem....
What Has the U.S. Gotten Out of the Space Program�
Since the time of its creation in 1958, the National Aeronautics and Space Administration has spent billions of dollars on space activities. What has the U.S. gotten out of these tremendous...
