Noise from High Speed Maglev Transportation Systems
Noise levels from magnetically levitated trains (maglev) at very high speed may be high enough to cause severe environmental noise impact in residential areas, even without physical contact...

A Combined Noise Model for HSGT Traffic
Environmental concerns are high on the list of possible problem areas for proposed high speed ground transportation (HSGT) systems. A Federal Highway Administration (FHWA) Highway Traffic...

High-Speed Rail's Prospects in Canada
This paper reviews the attractiveness of high-speed rail in Canada. It summarizes the findings of studies on the subject by VIA Rail, Canada's national passenger rail corporation. VIA...

Water Management in the '90s
A Time for Innovation
This proceedings, Water Management in the '90s: A Time for Innovation, contains papers presented at the 20th Anniversary conference...

Getting to the Nonpoint Source with GIS
Like most densely populated areas in the U.S., the Galveston Bay in Texas suffers from non-point-source pollution. Engineers working under guidelines of the Galveston Bay National Estuary...

Shelter from the Storm
Assuming that EPA meets its most recent deadline (Octobet 31, 1993), municipalities (cities and counties) with populations of less than 100,000 that own or operate separate storm-water...

Characterizing Coastal Pollution Sources: Lessons Learned by the National Coastal Pollutant Discharge Inventory Program
The past ten years, NOAA has been developing and refining its capabilities to inventory and estimate pollutant discharges form point and nonpoint sources located in the Nation's coastal...

Petroleum Imports and Coastal Zone Management
With its growing net petroleum import position, the U.S. must accept continued dependence on tankers plying its coastal areas. Tankers also carry product exports, of course, a critical...

The National Status and Trends Program: Development and Future Directions
NOAA's National Status and Trends Program was initiated in 1983 to provide information on environmental quality related to levels and effects of toxic contaminants in U.S. coastal and...

Status of Contamination in the Coastal United States as Revealed from NS&T Analyses of Surface Sediments
Sediment samples have been collected from more than 300 sites along the coasts of the U.S. since 1984 as part of NOAA's National Status and Trends (NS&T) Program. These samples...

Temporal Trends of Chemical Contamination at NS&T Sites
Recent temporal trends in concentrations of ten trace elements (Ag, As, Cd, Cr, Cu, Hg, Ni, Pb, Se, and Zn) and of five groups of organic compounds (butyltins, tDDT, tCdande, tPCB, and...

The NS&T Intensive Bioeffects Surveys: Design Strategies and Preliminary Results
Intensive bioeffects surveys are conducted in selected areas where chemical data from the National Status and Trends (NS&T) Program indicate greatest potential for contaminant-related...

Recovery of Shoreline Ecosystems Following the Exxon Valdez Oil Spill and Subsequent Treatment
High-pressure, hot-water washing was evaluated as one of several countermeasures for cleaning oiled shorelines. This was the primary treatment method for nearly all treated shorelines...

GIS and Laboratory Study Contaminants in Wetlands
Geographical Information Systems (GIS) provide excellent visualization and analyses of where pollution sources are located relative to existing wetland resources and areas of significant...

Evaluation of Dissolved Oxygen and Nutrient Trends in the Houston Ship Channel from Historical Statewide Monitoring Data
Dissolved oxygen and selected nutrient trends in the Houston Ship Channels (Texas Water Commission (TWC) segments 1007, 1006 and 1005) during the period of 1969 through 1990 were evaluated...

Effects of Estuarine Habitat Quality on Juvenile Salmon: I. Chemical Contaminant Exposure and II. Altered Growth and Immune Function
Some urban estuaries on the west coast of the US are important habitats for several species of juvenile salmon and receive multiple stresses from human activities. Because these estuaries...

Proposed Storm Water Management Programs: An Opportunity for Coastal Municipalities to Improve Water Quality
On November 16,1990, the Environmental Protection Agency (EPA) promulgated a final regulation establishing National Pollutant Discharge Elimination System (NPDES) permit application requirements...

Modern Air Pollution Reduction Technology on Platforms in the Pacific OCS
The Pacific Outer Continental Shelf (OCS) along the California coast line has the most sophisticated air pollution reduction technologies implemented in the world. This paper describes...

Sandy Beach Restoration in Heavily Populated Areas
Urban coastal areas are marked by several conflicts between its use and the conservation of its use and the conservation of its natural features. The Rio de Janeiro State University -...

The Source of Sediments in the Neuse River Estuary: Water Quality Management Implications
Pedological evidence in alluvial floodplains of the fluvial-estuarine transition zone of the Neuse River, North Carolina, shows that very little sediment from the Piedmont headwaters of...
