Acoustic Silt Density Measurement
Significant savings can be achieved on the costs of operations for the deepening and maintenance of navigation channels and harbor basins in muddy areas provided that computations are...
Aquaculture in Dredged Material Containment Areas
The beneficial use of active dredged material containment areas through aquaculture appears to offer, under certain circumstances, benefits to the Federal government, municipal and industrial...
Overtopping of Flood Control Levees and Floodwalls
The risk of overtopping can be significant for flood control levees or floodwalls, and the consequences can be costly and potentially catastrophic. Designs using superiority can force...
Mackenzie River Breakup: Ft. Simpson to Ft. Good Hope, N. W. T.
Breakup progression on the Mackenzie River in 1982 and 1983 is described. Two types of breakup, and two types of ice jam formation associated with these, were identified. The major role...
Reduction of Intake Flow Due to Ice Rubbling and Consolidation
Numerous seawater intakes have been designed for Arctic Coastal Waters. In these areas moving ice often causes rubbling and pile up of broken ice pieces against the shore. If this forms...
Stochastic Analysis and Modeling Levels of a Land-Locked Lake for Resource Development
Lakes are valuable natural resources that can be tapped for recreational, agricultural and other extensive lake side developments. Natural variability of lake levels is an important factor...
Afloat on the China Sea
In the summer of 1982, the Science and Technology Commission of the People's Republic of China invited four United States tunnel experts to come to China to engage in technical...
Holland's Fight Against the Sea
The Netherlands have always been threatened by the sea, its Delta Region most of all. After the catastrophic floods of 1953, the Delta Plan for the strengthening of coastal defenses and...
A New Panama Canal?
The Panama Canal is expected to be obsolete by the end of the century. Already there are serious problems with ship traffic through the Canal: volume of traffic is down, average transit...
Coastal Zone '83
Interdisciplinary information and viewpoints on coastal zone management and ocean resources issues related to use, protection, and development are presented. Topics include improved jurisdiction...
EPCOT
EPCOT Center, perhaps the most elaborate and futuristic entertainment attraction in the world, is also a major achievement in such civil engineering-related disciplines as geotechnical,...
Artificial Islands
Artificial islands constructed from gravel fill have become a preferred approach to drilling for oil in hostile Arctic environments. These man-made islands are being built to serve as...
Characterization of Offshore and Coastal Ice Conditions
Seasonal sea ice conditions typical of nearshore coastal zones are reviewed. Prominent ice features influencing design ice conditions for offshore structures are described. This paper...
Design of Port and Coastal Structures for Ice Forces
Design of ice-affected port and coastal structures cannot be addressed in a few single specific terms, but must instead account for a matrix of elements differing at each site. Evaluation...
Pier Stabilization Eliminates Need to Reconstruct Damaged Bridge
After an ice jam near a six-span bridge restricted normal water passage, the ensueing high velocity water caused underscouring of one of the piers, leaving it ineffective as a bridge support....
Oil Rigs Designed to Combat Arctic Ice
Exploration and drilling rigs now being designed for use in the Beaufort Sea must withstand ice forces never before encountered. Design approaches include using the geometry of these structures...
Journal of Waterway, Port, Coastal, and Ocean Engineering
The Journal of Waterway, Port, Coastal, and Ocean Engineering presents information regarding the engineering aspects of dredging, floods, ice, pollution, sediment transport, and tidal wave action that...
Law of the Sea: U.S. Votes No
The United States has voted against the international treaty which will regulate ocean and waterway passage, ocean mining, and fishing rights. Implications are far reaching as the precedents...
Jubail Industrial City: Engineering Monument
The seawater cooling project is a major innovation in engineering accomplishments. Here the project engineers discuss the key civil engineering aspects of the Jubail, Saudi Arabia project...
Sulfer Extended Asphalt
Since the 1973 oil embargo, the Federal Highway Administration has researched and promoted the experimental use of a new pavement binder, sulfur-extended asphalt (SEA). In SEA paving mixes,...
