Geologic Review: A Successful Procedure for the Minimization of the Impact of Oil and Gas Exploration and Production on Louisiana Wetlands
An effective procedure to minimize the amount of wetlands impacted by oil and gas well access routes has been developed. The procedure consists of a stringent geologic review of every...
Waterfront Projects and the N.J. Green Acres Program
Under the New Jersey Department of Environmental Protection, the Green Acres program has been at the forefront of the state's commitment to open up its beaches as well as...
Rising Sea Level, Storms, and Coastal Erosion at Ocean City, Maryland
This paper describes the 'greenhouse effect', and its impact on future sea level rise; provides an overview of the possible impacts on Maryland and other coastal...
The Emergence of Am?nagement in the California Coastal Zone
For several decades now the California Coast has been under intense development pressures. The passage of Proposition 20 in 1972 and the subsequent package of Coastal Legislation in 1976...

Recent Developments
The Foothills Project has been under consideration by the Denver Board of Water Commissions for many years. It is one of the major steps in the continued efforts of the Board to provide...
Rock Masses
Modeling of Underground Openings/Probability of Slope Failure/Fracture of Intact Rock
While soil mechanics has been the dominant interest of Civil Engineers since Karl Terzaghi's recognition of the principle of effective stress, rock mechanics is becoming increasingly...
The Tunnel That Transformed Philadelphia
The 1985 Outstanding Civil Engineering Achievement is the Center City Commuter Rail Connection, a 1.7 mile tunnel connecting two former stub-end railroad stations in Philadelphia. The...
Effects of Vehicles on Buried, High-Pressure Pipe
The mechanical effects of selected types of traffic on buried, high-pressure steel pipe are examined. Particularly considered is a section of the Colorado Interstate Gas (CIG) pipeline...
Influence of Depth-of-Cover on Pipe-Soil Interaction
A major research effort was undertaken to study the structural behavior of a natural gas pipeline under several critical service conditions. The program included a field test site near...
An Instrumented Soil-Pipe System: Automated Data Acquisition and Management
A 16-in. natural gas pipeline near Racine, Wisconsin, had been in service for some 30 years. In 1982 road widening operations on a line parallel with the pipe resulted in a heavily trafficked...
Unique Installation Methods for Large Interceptor in Poor Soil Conditions
The construction of approximately 1. 5 miles of a major sewer interceptor in downtown Boston encountered some unique construction challenges. The entire route required dewatering during...
Longitudinal Prestressed Piping for District Heating
The design of recently installed hot water district heating systems in the United States is based on similar systems developed in Europe. Longitudinal prestressing is used in the design...
Stiffness Requirements for HDPE, Profile Wall Pipe
For the past two years the Gulf Oil Corporation has sponsored a research study on profile wall High Density Polyethylene (HDPE) pipe at Texas A & M University. A pipe design computer...
Dynamics of Buried Pipelines
Forced motion of pipelines due to stationary or moving loads is studied. The pipe is modeled as an elastic shell in an elastic (or viscoelastic) medium. The interaction of the shell and...
