Coral Reef Modeling: Key Largo Case Study
A numerical model called CORALSIM has been developed for the Key Largo Coral Reef National Marine Sanctuary in the Florida Keys. The model was developed as a management tool to study the...
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...
Off-Site Water Quality or On-Site Productivity
Nonpoint sources of pollution are being recognized as the primary source of water quality degradation in many coastal areas. In those areas where management programs are being implemented,...
A Study of Selected Environmental Parameters of Small Coastal Lagoons as a Function of Extent of Urban Development, Hydraulics of the Tidal Inlet, and Hydrology of the Contributing Drainage Area
In coastal areas many small brackish water lagoons or embayments connected to the sea by small tidal inlets are at tractive to residential and commercial developers, especially those emphasizing...
Federal Policies in Water Resources Planning
The adequacy of current federal policies and institutional arrangements for water resources planning is assessed. Conclusions and recommendations are presented in five key areas: (1) Water...
Watershed Management in the Eighties
The papers included in this publication discuss state-of-the-art methods and current research on management and present case studies on current projects and practices on applied watershed...
Measurement and Use of Shear Wave Velocity for Evaluating Dynamic Soil Properties
Geotechnical engineers have recognized in the past decade that shear wave velocity is a basic soil property and have begun to use it to characterize sites for many uses. Most notable has...
Hydraulic Fill Dam Made Earthquake Resistant
San Pablo Dam, near the San Andreas fault, constructed in 1919-21 by hydraulic fill methods, was found to be susceptible in places to liquefaction under seismic loading. The dam has been...
Coping with Litigation
Engineers should learn legal philosophy, even though it seems unrelated to traditional technical practice. Monitoring changes in legal theory that may increase engineers'...
Tapping Deep Water Resources
Lena is the first commercial guyed tower. Its jacket is the longest ever fabricated, loaded out and launched in one piece. Lena stands in 1,000 ft deep water and has a three-level oil...
Project Mixes Oil and Water
The Prudhoe Bay Seawater Treatment Plant was nominated for an OCEA award, for its potential to coax from Alaska's north slope 1 billion barrels of oil which otherwise would...
Bridging Twin Ports
The Major Richard I. Bong Memorial Bridge, part of U. S. Highway 2, connects harbors at Duluth, Minn. and Superior, Wisc. The new highway link was designed to relieve congestion on nearby...
Effect of Shallow Trench Construction on Cast Iron Pipelines
This paper summarizes the results of three-dimensional finite element analyses to evaluate the strains and displacements sustained by 4, 6, and 8-in. (100, 150, and 200 mm)-diameter cast...
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...
Clay Pipe Installation?Advances in Load Factors
This report presents an evaluation of traditional load factor values for clay pipe and the development of a new bedding system which gives a higher load factor. Tests demonstrate that...
Sewer Construction Inspection and Testing
Sewer construction testing is the final portion of the team effort that started with the goal of meeting the requirement for a sewer system for the protection of health and environment....
Investigations into the Structural Performance of Clay Pipes
Over the past 8 years, the Clay Pipe Development Association (CPDA) has commissioned non-destructive physical testing of vitrified clay pipelines. The diameters of the pipes have varied...
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...
Failure of a Large Reinforced Concrete Pipeline
This paper describes the damage that occurred when a landslide overloaded an 11 ft diameter reinforced concrete pipeline. The 8 ft lengths of pipe, each of 11. 5-in. wall thickness, were...
