Managing the Dunes and Wetlands of Norfolk, Va.
The Code of the City of Norfolk was amended in 1982 to establish a procedure for permitting and preservation of the city's saltmarshes and sand dunes. A Wetlands Board was...
Sand for Beach Nourishment in Lower Chesapeake Bay
The Virginia Institute of Marine Science designed and performed an inventory of the resources of sand in the southernmost portion of Chesapeake Bay. The primary purpose of the project...
A New Method for Effective Beach-Fill Design
Beach nourishment with sand fill has been extensively used to restore recessional beaches, but the success of this method has been variable due to a poor understanding of sediment dispersion...
Stabilization of Dunes with Flexible Mattresses
Dunes, constantly moving due to influences of sea and wind, are inherently unstable and in many, if not most situations, are best left in their natural state of change. Where there is...
Some Econological Observations on Coastal Plant Communities, of New York and New Jersey
The present study was conducted at three coastal sites, Fire Island, New York, Fort Tilden, New York, and Sandy Hook, New Jersey. Four plant communities, the salt marsh community, sand...
Man-Made Offshore Islands: An Innovative Solution to Coastal Erosion
Existing shore-parallel detached breakwaters have resulted in the accretion of sand along the shoreline in the wave shadow of the structure. Significant prograding of the beach has replaced...
Modeling the Fate and Transport of Biocides in Estuarine Power Plant Cooling Water Discharges
This paper presents a framework with examples for understanding the fate and transport of cooling system discharges into estuaries through the use of modeling. The modeling of biofouling...
Managing Shoreline Changes in the Presence of Nearshore Shoal Migration and Attachment
The purpose of this paper is to describe these events in detail and illustrate the need for better understanding of erosion/deposition patterns around tidal inlets. Periodic beach surveys...
Experimental Study on Sandbag Stability and Runup
Sandbag model tests are performed in a wave flume to examine the effects of berm-type slopes on the stability of sandbags and wave runup as compared to uniform slopes. Measurements of...
Discharge Zone Classification System for Southern Puget Sound
This paper identifies marine areas where new or expanded discharges are unacceptable based on existing knowledge; e. g. , water quality standards are currently not met, and impairment...
Improvement and Construction of Coastal Fishing Grounds in Japan
Development of coastal fishery has become one of the most important issue in the field of food supply. Basically, in order to promote coastal fishery, it is necessary to increase marine...
Beneficial Use of Municipal Sewage in the Ocean
When sewage sludges and effluents are introduced in a properly controlled manner, they can be of benefit to large areas of the ocean. For example, benthic biomass and growth rates of commercially-valuable...
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...
Waste Cleanup: Lessons Learned
Since hazardous waste mitigation is a new science, engineers need to pass on their experiences. The U. S. Army Waterways Experiment Station, seeking to expand the hazardous waste knowledge...
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...
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...
