Deterioration Models for Highway Bridges
Infrastructure management, especially in case of highway bridges, need a realistic and effective deterioration model in order to provide information on the present and future condition...

Digital Imaging as a Design Tool
On most engineering projects, schematic drawings offer a technical representation of a structure to clients. For staff or the public who are not technically knowledgeable, though, schematics...

Energy Facility Siting in Coastal Zones
Siting constraints to the development of coastal energy facilities may lengthen or complicate the siting process. These constraints have evolved over the history of coastal energy facilities....

Use of Geographic Information Processing for the Identification of Indirect Impacts Associated with Regulatory Permitting Programs: For Now, a Conceptual Model
The utilization of Geographic Information Processing (GIP) for the identification and assessment of direct impacts to coastal ecosystems allowed under the guidelines of regulatory permitting...

Processes Affecting Coastal Wetland Loss in the Louisiana Deltaic Plain
Nowhere are the problems of coastal wetland loss more serious and dramatic than in the Mississippi River deltaic plain region of south-central Louisiana. In that area, rates of shoreline...

Natural Resource Problem Solving: an Interdisciplinary Approach in Coastal Louisiana
Ecological issues such as coastal wetland loss cannot be adequately addressed by experts in any one particular discipline. After extensive consultation with wetland users and regulators,...

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...

Are Landscape Patterns Related to Marsh Loss Processes?
Marsh loss that occurs in Louisiana is seldom associated with shoreline erosion of lakes and bayous; instead, marshes break up internally. Marsh loss is attributed to processes that stress...

Production and Decomposition of Spartina patens in a Degrading Coastal Marsh
Production and decomposition rates were calculated for Spartina patens in a mesohaline coastal marsh in Louisiana. Production was estimated to be 800 g m-2 ur-1 during 1991 and 1,696 g...

Results from Minerals Management Service Funded Oil Spill Response Research 1991-1993
Large oil spills from tankers have reaffirmed the need for continuing technology assessment and research to improve oil spill response capabilities. This paper discusses Minerals Management...

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...

A Workstation for the Extraction of Coastline from Digital Imagery
The delineation of coastline has primarily been a manual tracing exercise from various forms of imagery. In this paper, a process to extract shoreline automatically from digital imagery...

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...

State Implementation and Enforcement of the Alaska Coastal Management Program
Section 306 the Coastal Zone Management Act of 1992 required participating states to develop a means to implement and enforce their coastal programs. The Alaska Coastal Management Act,...

The Permitting Process for Oil Exploration and Development Projects on the North Slope of Alaska?An Oil Company Perspective
The five oil fields of Alaska's North Slope, including the giant Prudhoe Bay field the largest oil field in North America, contribute approximately 25% of United State domestic oil production...

Using GIS and Image Processing Technology to Assist Wetland Planning, Protection, and Restoration in Coastal Louisiana
Coastal Louisiana has experienced severe wetland loss over the past 30 years. The Coastal Wetland Planning, Protection, and Restoration Act (CWPPRA) of 1990 was created to address the...

Beach Stability and Coastal Erosion in the Eastern Caribbean Islands-A Regional Programme
The problems associated with coastal erosion have been facing the smaller islands of the Eastern Caribbean for many years. The skills necessary to manage the problems have not been available...

Traffic and Lead Pollution on Lake Maracaibo's Western Coast
This project focused on Nerium Oleander (NO) (Berberia), an ornamental plant. Chemical analyses (acid digestion and atomic absorption spectrophotometry) of the plant's tissue and the soil...

NOAA, Bioassessment Techniques and the Superfund Process
The National Oceanic and Atmospheric Administration's (NOAA) assessments of SUperfund sites require an evaluation of whether contaminants are present in an aquatic environment of concern,...

Methods to Assess Ecological Risk Used at Superfund Mega-Sites
This paper presents a variety of approaches that have been used (or are proposed) to address the potential ecological risks posed by contaminant releases from Superfund mega-sites. The...
