Dune Construction on Perdido Key, Alabama
In recent years, the Alabama coast has experienced significant pressures for development. To make development compatible with beach preservation, the Alabama Department of Environmental...
Low-Cost Stacked Block Revetments for Great Lakes Shores
Two stacked-block revetments, the product of emergency conditions and budget limitations, were constructed at Illinois Beach State Park on Lake Michigan in April 1982. The revetments,...
Studies in an Unproductive Coastal Lagoon in South Texas: A Case Against One-Time Sampling for Environmental Assessments
This study illustrates the problems inherent in attempting to write an environmental assessment based on inadequate or misleading data. Results can be biased against environmental preservation...
Sea-Level Rise and Marsh Vertical Accretion Rates in Chesapeake Bay
Chesapeake Bay marshes, in their wide variety of vegetation types, salinity ranges, and environmental settings provide a unique perspective on the relations between marsh vertical accretion...
The Suwannee River Estuary: Cohesive Sedimentation
Cohesive sediment dynamics as effected by salinity intrusion are described for the Suwannee River Estuary, a large estuary flowing over the very shallow limestone shelf of Florida's...
Marine Geological Studies on the Coastal Zone of Kerala
The largest of the estuaries in Kerala, the Vembanad lake formed by the backwater, has been investigated in detail with reference to bathymetry, sediments and geochemistry. A considerable...
Multidisciplinary Barge Fleeting Site-Evaluation
The U. S. Maritime Administration, in cooperation with the State of Louisiana, recently (March 1985) released a major report on barge fleeting on the Lower Mississippi River. The study...
A Tidal Gauge System in New York Harbor
For over a year, a Real Time Wind and Water Level Telemetry System (RTWLTS or Tidal Gauge System) in New York Harbor has been generating real time data 24 hours per day on actual harbor...
Effects of Dune Stabilization in North Carolina
This study analyzes changes occurring between 1937 and 1977 in the beach/dune complex along the Outer Banks of North Carolina due to the construction of a barrier dune system. Data for...
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'...
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...
LAX Engineers Beat the Clock
Foreign and domestic crowds flying in for the Olympics were no problem for the Los Angeles Airport (LAX), thanks to the expansion and improvements completed a month earlier. LAX more than...
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...
Microcomputers in Highway Drainage Design
This paper discusses some of the benefits and uses of microcomputers in highway drainage design and discusses the programs presently being developed. Subjects covered include hydrologic...
Vertical Transport of Fine-Grained Sediments in Suspensions
Numerical-model sensitivity studies were made to determine the effect of bed flux on the vertical distribution of fine-grained material suspended in turbulent flow. The transport equation...
Numerical Modelling of Pollutant Transport from a Pond to a Stream
The problem of transport of pollutants in groundwater flow from a polluted shallow pond to a natural stream is considered. A numerical model predicting changes in quality of ground water...
Numerical Modeling of Fine Sediment Physical Processes
Fine sediment in channels, rivers, estuaries, and coastal waters undergo several physical processes including flocculation, floc disruption, deposition, bed consolidation, and resuspension....
Prediction of Shoaling in Estuarial Channels: A Microcomputer Application
Shoaling rates at three predominant areas of sedimentation in the Hooghly River estuary, India, have been predicted using a sediment transport model run on an IBM compatible microcomputer....
The Impact of the I-664 Bridge-Tunnel Crossing on Sedimentation
A sedimentation evaluation was made of the proposed I-664 Bridge-Tunnel complex across the James River, Virginia. This paper briefly describes the procedures used and the results obtained...
Tidal Inlet Sand Transport in Rollover Pass, Texas
For Rollover Pass, which is a man-made, artificially stabilized tidal inlet located on the upper Gulf Coast of Texas, the magnitude of the net sand transport through the Pass was estimated...
