Investigation of Coastal Conditions at Oregon Inlet, NC for the Replacement of the Herbert C. Bonner Bridge
The Bonner Bridge across Oregon Inlet was constructed in 1962 and is approaching the end of its service life. Planning for a future crossing must consider natural inlet migration expected...
Scour Hole Development and Stabilization at Shinnecock and Moriches Inlets, New York
A scour hole developed inside the Shinnecock Inlet channel near the tip of the west jetty. Over the years, this hole deepened to about 70 ft below the mean low water level with the average...
Longshore Sediment Transport Rate at Morro Bay, CA
Estimates of sediment transport rate in the vicinity of Morro Bay Harbor are needed as part of an investigation of possible modifications to the existing Federal project. Because the site...
Alternative Study for the Breakwater and Fishing Pier Rehabilitation at Playland Park, Rye, New York
An alternative study was conducted to determine that existing condition of a deteriorated timber pier and a rubblemound breakwater, and to develop alternative rehabilitation plans leading...
Design of a Mechanical Refuse Barrier
In the summer of 1988, beachgoers flocking to the New Jersey shore for relief from unusually hot, hurried weather were stunned by the grisly spectacle of hospital debris, industrial and...
Wave Forecasting for Construction in Mobile Bay
Wave heights were forecast for day-to-day pipeline construction operations in the Main Pass area of Mobile Bay. A low-cost forecasting procedure was developed using the wave generation...
The Talbert Channel Ocean Outlet Project
The Talbert Channel Ocean Outlet Project consisted of relocating and enlarging the outlet of a relatively narrow, shallow flood control channel in Southern California. Noteworthy aspects...
Construction on Wisconsin's Lake Michigan Coast
This paper provides a preliminary evaluation of a set of 100 residential properties along Wisconsin's Lake Michigan coast; an examination of the vulnerability of coastal homes and adequacy...
Design Considerations for Small Artificial Islands in Franks Tract, California
Small, artificially-created islands may provide significant recreation and habitat benefits. Costs, however, can also be high. The initial dollar cost of creating an artificial island,...
A Design Manual for Coastal Fluidization Systems
This paper summarizes a recently completed design manual on fluidization systems to manage sand in the coastal environment for sand bypassing at inlets and harbor mouths and for creating...
Robust Approach to Wave Runup Calculation
Wind wave runup on a natural beach is examined for the case of an irregular wave forcing function. A pragmatic approach to the calculation of the runup time series and the corresponding...
Remote Automated Wave and Water Level Monitoring System Deployed at Agat Harbor, Guam
Agat Harbor, Guam is a small boat harbor excavated from a coral reef flat and protected by a detached breakwater. An automated monitoring system was designed and installed to observe wave...
Environmental Effects of Beaufort Sea Causeways
Two gravel-fill causeways have been constructed into the shallow nearshore Beaufort sea on the north coast of Alaska for the development of petroleum reservoirs. These long (4-8 km) structures...
Coastal Engineering Design Codes in the Netherlands
Dutch research strategy on water defences and the resulting coastal and hydraulic engineering design codes (technical documents) are briefly overviewed. Special attention is paid to organizational...
Should the U.S. Accept the Concept of Navigable Depth?
Navigable depth is defined as the maximum depth of water from the chart datum that is safe to accept as the bed of the channel, such that damage does not occur to a ship's hull and maneuverability...
GIS: New York's Pipe Dream
To be of any use to managers, infrastructure data must be compiled in a form they can use. The answer for the 1990s is a geographic information system that electronically combines data...
Tackling Trapped Sediments
Crater-sink fluidization has been used to recover sediment from harbors for the past couple of decades. Can this method bypass sediment around dams and return it to eroded beaches, solving...
Dynamic Compaction of Nuclear Waste
When ponding, caused by settlement of the original soil cover over low-level nuclear waste buried at the Department of Energy's Savannah River Nuclear Plant near Aiken, S.C.,...
Cleaning Up Chromium
From 1956 to 1985, the United Chrome Products plant in Corvallis, Oregon, took a steady toll on the environment. Leaky plating tanks and the discharge of rinse water into a disposal pit...
Controlling Nitrogen in Coastal Waters
Excess nitrogen in coastal waters is becoming a problem worldwide. Nutrients such as nitrogen come from sewage treatment plants, septic tanks, runoff from fertilizer and animal waste,...
