Effects on Seismic Spatial Variations to Suspension Bridge Responses
The dynamic soil-structure interaction effects and spatial variations of a seismic motion seem to have significant contributions on the response evaluation of a long span suspension bridge....
Measurements of Nutrient and Metal Fluxes from the Sea Floor in the Area Around the Whites Point Sewage Outfall, Los Angeles, California
Studies are underway to determine the influence of sewage outfall-impacted sediment on the exchange of nutrients and trace metals in the coastal marine environment. Utilizing a benthic...
Mixing and Dispersion Processes in the Vicinity of an Ocean Outfall System in Southern California
Ocean wastewater plumes are important for the disposal of municipal wastes in Southern California. These plumes, which are discharged from sanitation systems, can be distinguished in the...
Aerial Videotape Mapping of Coastal Geomorphic Changes
An aerial geomorphic mapping system was developed to examine the spatial and temporal variability in the coastal geomorphology of Louisiana. Between 1984 and 1990 eleven sequential annual...
Long Term Assessment of Beach Nourishment Project Performance
Long-term data on profile response, sediment distribution and wave information have been collected and analyzed for the Indialantic/Melbourne Beach beach nourishment project in order to...
Assessment of the Nearshore Zone at St. Marys Inlet, Florida
St. Marys Inlet connects Cumberland Sound from the Atlantic Ocean and actually forms the coastline border between Georgia and Florida. Drumstick shaped barriers are located to the north...
Management of Sandy Inlets: Coastal and Environmental Engineering Imperatives
Management of sandy tidal inlets is required for maintenance of navigable channels and control of beach erosion. Management elements essentially entail 'resharing'...
Controlling Parameters on Littoral Transport and Coastline Development
An extension to the one-line approach to coastline development modelling is presented in the light of the major parameters influencing the longshore sediment transport processes. The model...
Hydrodynamic Behavior of Cohesive Sediments in Turbulent Flow
To meet both engineering and basic research requirements, a series of experiments on the deposition of cohesive soil were conducted in an annular rotating fiberglass channel-ring system...
Pollution Control Strategies of the Puget Sound Water Quality Management Plan: Puget Sound Water Quality Authority
In 1988 EPA designated Puget Sound as an estuary of national significance under section 320 of the Clean Water Act. Due to its natural beauty, favorable climate, and economic health, the...
Port Layout Optimization for Large Bulk Carriers in a Strong Tidal Currents Site
To provide the sheltering conditions of Ponta da Madeira Terminal (TPM) in Sao Marcos Bay, in Sao Luis, Brasil, two rubble mound groins were designed and constructed according to hydraulic...
The Construction of the Shanghai Port and Its Sea-Entering Channel
The Shanghai Port, the biggest port in China, has not enough passing capacity. In order to solve this problem, some new ports must be built. According to sedimentation, fluvial processes...
The Torres Strait Baseline Study: Environmental Protection of a Tropical Marine Environment in Northern Australia
This paper discusses the potential impacts of mining in the Fly River catchment area of Papua New Guinea on the Torres Strait marine environment and the customary ways of life of the Torres...
The Case for Managed Open Water Disposal of Sediments Containing Low Levels of Dioxin
Between 6 and 8 million cubic yards of material is dredged annually from the 240 miles of federal channels and approximately one million linear feet of berthage of the Port of New York/New...
Geological Assessment of Offshore Sand Deposits
The United States Atlantic and Gulf of Mexico continental shelf contains large numbers of surficial sand deposits. The search for sand resources for metropolitan construction and coastal...
An Offshore Borehole Mining Experiment: Its Operational and Environmental Implications
The Continental Shelf Division of the Marine Minerals Technology Center (MMTC), conducted a miniborehole mining experiment offshore Georgia in June 1990. A remote placer drill developed...
The Physical Evolution of a Wetland Restoration
Since European colonization, San Francisco Bay has lost 95 percent of its original wetlands. The success of recent efforts to restore wetlands throughout California and the U.S. cannot...
New Directions for NOAA/NS&T Program: Historical Reconstruction of Sediment Contamination Using Dated Cores
Sediment cores sampled in coastal and estuarine areas can be used to reconstruct historical trends in sediment contamination. The sediment cores have to be undisturbed in order to obtain...
Responses of Benthic Macrofauna to Phaseout of Sewage Sludge Disposal in the Inner New York Bight
From 1924 through 1987, sewage sludge was dumped at the '12 mile site' 22 km off northern New Jersey in the inner New York Bight. Inputs in the early 1980s were,...
Beach Erosion in the Town of Jupiter Island: Causes and Remedial Measures
St. Lucie Inlet, located on the lower east coast of Florida, was cut across a barrier island in 1892 and jetties were constructed on the north and south sides of the inlet in 1926 and...
