A Practical Approach to Regulating Energy Development in Alaska's North Slope Environment
In November 1983, the Alaska District, Corps of Engineers (Corps) established an abbreviated processing procedure (APP) to permit certail oil and gas related activities within the North...
Monitoring of Water Quality During I-664 Dredging
Construction of Interstate Highway I-664 across Hampton Roads involves extensive underwater work and consequent risk of lowered water quality. This paper described field monitoring procedures...
The Great Highway Coverup
Public opinion has forced changes in highway design since the first ones were built 30 years ago. In the Seattle area, this environmental sensitivity led to federal court action and to...
Arctic Wetland Losses: When Should Compensation be Required?
The paper discusses problems facing biological impact assessment and mitigation planning for petroleum exploration and oilfield development on the Arctic Coastal Plain or North Slope of...
Can Alaskan Caribou and Oil Development Coexist?
The coastal area near Prudhoe Bay, Alaska is becoming increasingly industrialized as oil development continues. This same coastal area is an important area to a caribou herd known as the...
Caribou Mitigation in an Arctic Oilfield
The Kuparuk oilfield on the Arctic coastal plain of Alaska is in an area of traditional summer use by the Central Arctic Caribou Herd, who use it for calving, feeding, and insect relief....
Barrier Beach Management: The Long Island Experience
Barrier beaches are intrinsically unstable but are used for a variety of human activities ranging from recreational to commercial use. This type of land use often leads to the demand for...
Barrier Island Reconstruction in Louisiana
The Terrebonne Parish Government reconstructed thirty-eight (38) acres of Eastern Isle Dernieres, a barrier island off the coast of Louisiana, in an effort to retard coastal erosion (Figure...
The Identification of Common Resource Management Needs as a Basis for Barrier Island Research Programs
This paper demonstrates the need for a broad, centrally focussed barrier island research program by conducting a systematic analysis of the resource management needs of the Atlantic and...
An Innovative Solution to the Difficult Coastal Zone Management Problem of Dredge Material Disposal
The New York Power Authority is constructing a 300 km predominantly double circuit 345kV transmission facility through southeastern New York State. A key element in this project is the...
Sea Level Change and Coastal Geomorphology of Padre Island, Mexico
Extending some 244 km from the Rio Bravo (Rio Grande) on the north to the mouth of the Rio Soto la Marina (at La Pesca) on the south, Padre Island, Mexico is comprised locally of several...
Golden Gate Bridge Improvements
The Golden Gate Bridge, Highway and Transportation District engineer talks about improvements made to the Golden Gate Bridge since opening day. Improvements covered include: wind bracing,...
Significance of Mean Water Level Response in Bays
The occurrence of a net hydraulic head, or superelevation, is a basic feature of bays. It is generated by inlet-bay response to natural forcing. The effects of bottom friction and Stokes...
Analysis of Scour Problems at Louisiana Bridges
An ongoing project to automate the monitoring of scour measurements at Louisiana bridge sites is discussed. The data at selected bridges is digitized and put into computer files for analysis....
Modification of Meander Pattern Using Wing Dams
A sharp river bend and a highway bridge together create potentially hazardous conditions for all down-bound barge tows on the Mississippi River at Lansing, Iowa. The tendency of the river...
Calibration of a Bridge Rating Formula for Overload Permits
This paper proposes a method to calibrate a reliability based load and resistance factor design (LRFD) permit evaluation formulation that will account for the overloaded truck's...
Multiple Presence Reduction Factors for Bridges
This paper reviews the multiple presence reduction factors specified in the AASHTO and Ontario codes, and provides a method by which these factors can be established in relation to volume...
Queensboro Bridge Inspection and Rehabilitation
An in-depth inspection of the Queensboro Bridge revealed deterioration of certain elements on the lower level of the main bridge. These elements include the outer roadway cantilever brackets,...
Development of a Double Tee Structural System for Highway Bridges
The fully precast, prestressed double tee beams are tied together by transverse post-tensioning through simple grout filled V-joints. The system provides for complete transversal continuity...
The Behavior of R/C Pinned Bridge Columns under Lateral Loading
Four one-eighth scale one-way hinge details of the type used in highway bridges were tested to study the effect of combined shear and flexure caused by lateral loads. The aspect ratio...
