Contaminants in Mussel Tissues from U.S. Coastal Waters
Findings are presented from analyses of mollusks collected from sites along the East and West Coasts of the United States, from 1986 through 1989, by the National Oceanic and Atmospheric...

Pre-Operational Considerations for Marine Finfish Aquaculture: Site Selection and Allocation in British Columbia
Marine fish farming is a new component in the complex mixture of coastal resource uses in British Columbia. To ensure that the marine finfish aquaculture industry develops within an environmentally...

A Systematic Analysis of Disposal Site Stability
This paper describes a systematic methodology for predicting the stability of dredged material disposal sites over long periods of time, ranging from months to years. The approach is based...

Analysis of Transport Processes on Ocean Disposal Mound
Disposal site 'F', an ocean disposal site for dredged sediments from Coos Bay, Oregon was designed to be a dispersive site. The site has not demonstrated high...

Integrated Waste Management at the Weldon Spring, Missouri Site Remedial Action Project
The diversity of contaminants and contaminated media at the Weldon Spring, Missouri CERCLA site, located about 30 miles west of St. Louis, Missouri, necessitates the formulation of integrated...

Constructed Wetlands at Mesquite, Nevada
Subsurface flow (SF) wetlands are used to provide effluent polishing following treatment in an aerated lagoon at Mesquite, Nevada. General SF wetland design methodology is discussed in...

California Standards for Characterizing Contamination and Assessing Risk from Hazardous Waste Sites
The Toxic Substances Control Program (TSCP) of the Department of Health Services is responsible for managing California's hazardous waste program. A primary goal of TSCP is...

Hydroproject Risk Analysis
Traditionally, feasibility studies performed for potential hydropower sites have included either no uncertainty or at best an ad hoc value associated with estimated benefits. However,...

EPRI's Pumped Storage Planning and Evaluation Guide
EPRI's Pumped Storage Planning and Evaluation Guide was published in 1990. The Guide provides step-by-step procedures to: (a) evaluate pumped-storage operation in a utility...

Small Hydro Site Ranking, Cost Methodology and Program
The user-friendly micro-computer program SHYDRO for costing small hydro has been prepared for the government of Canada and is available in the public domain. SHYDRO was initially applied...

Uplift Pressures and Strengths for Concrete Gravity Dams
This paper presents an overview of the results of a three year study to compile a database of stability parameters and foundation characteristics for older concrete gravity dams. The database...

Multi-Purpose Subsurface Drainage System for the Town of Saguache
The town of Saguache, Colorado had a high water table during the irrigation season that caused numerous problems within the town and resulted in high infiltration rates to the sewer system...

Effects of Soil Layering on Infiltration
The effect of sloping soil layers on infiltration depends on the textural composition of both layers at the interface, as well as the slope of the interface. The contractions of flow caused...

Shallow Groundwater Collection for Reuse in Irrigation
A prototype system of subsurface drains for collection of shallow groundwater and reuse of drainage water for reuse in irrigation was examined. The system involved a field with subsurface...

Interaction of Irrigation Water and Drainage Flow
This study was conducted to evaluate the effect of irrigation management on subsurface drainage flow in an arid irrigated area. The irrigation management and drainage flow were monitored...

Time Scales for Surface-Subsurface Flow Modeling
Traditionally, interactive free surface flow and subsurface flow are analyzed separately, using infiltration rate described by an infiltration formula as the common boundary condition....

Evaluating Probability Measures Related to Subsurface Flow and Transport: Overview of Technical Considerations and Modeling Philosophy
Probabilistic modeling approaches are being used increasingly in order to carry out quantified risk analysis and to evaluate the uncertainty existing in subsurface flow and transport analyses....

An Overview of EPRI Hydrogeochemical Code FASTCHEM^TM
The capabilities of the flow and transport modules that make up FASTCHEM are described. The linkages among the various modules that are required to achieve a hydrogeochemical analysis...

Practical Technology Resulting from MADE Research
As is often the case, when theoretical research is performed, practical technology is developed in the process. This has occurred with the Macrodispersion Experiment (MADE) conducted at...

Groundwater Models and Aquifer Restoration: An Overview
In recent years, as the demand for water has increased, groundwater mining has intensified. Data on water use indicate that this trend will continue in the future, and competition is likely...
