The Balanced Indigenous Population (BIP) and Statistical Process Control (SPC) in Marine Pollution Ecology
This account discusses the regulatory requirement of maintaining a Balanced Indigenous Population (BIP) as it relates to an ocean outfall. A brief history of the development of the BIP...
Soil Water Chemistry of Irrigation with Drainwater
The use of drainwater for irrigation was demonstrated as a management option that reduces net farm drainage and provides control over water quality (O'Brien and Guitjens,...
BMP for Control of Agricultural Nonpoint Source Flow
Nine ha of spring wheat were sprinkle irrigated with drainwater from 15 subsurface drains. The objective was to demonstrate that use of drainwater for irrigation improves the net efficiency...
Use of Channel Forming Discharge Concepts for Flood Control Channel Design
Evidence suggests that for perennial and ephemeral rivers that are in regime, bankfull flow is strongly correlated with channel morphology. Evidence suggests that this discharge is also...
Reversibility Measures for Sustainable Decisions
Increasing stress on the environment and current norms of sustainable development have prompted the formalization of new approaches to decision making. This may be achieved through the...
Risk as a Sustainable Development Criteria
Project alternatives can be compared on a relative basis when all factors contributing to social, environmental and economic risks are weighed by all the stakeholders concerned. It is...
Pollutant Transport Across Porous Stream Beds
The presence of porous streambeds generates a significant interaction between the main stream flow above it and the flow through the porous sub-stratum. This coupling affects both flows,...
Mixing Influences on Cement-Based Waste Forms
High-shear, medium-shear, and low-shear mixing tests were conducted on paste and paste + fly-ash mixes: The specimens, cured for 28-days, were tested for free water generation, compressive...
Innovative Effluent Management for Sustainability
The City of San Jose, California (USA) has developed an original, integrated approach to managing wastewater treatment plant effluent and preserving the receiving water ecosystem. Highlights...
A Process Unit Based Approach to Media-Integrated Waste Minimization: A Paint Manufacturing Case Study
Research conducted at the School of Engineering, University of Guelph, has developed a media-integrated waste minimization plan for a major Ontario paint and coatings manufacturer. The...
Modeling the Lake Decatur Watershed in Illinois to Evaluate Effects of Best Management Practices on Nitrate Loading
The Illinois State Water Survey recently completed a two-year monitoring and modeling study of the Lake Decatur watershed in Illinois to develop land use management alternatives that would...
Neural Networks Predict Pesticide Leaching
The goal of this work was to determine whether artificial neural networks (ANN) can be used to predict the percentage of applied pesticide that leaches through 50 cm of turfgrass covered...
Identifying Potential Trophic Relationships and Bioaccumulation Pathways between Fish and Invertebrates
A large ocean monitoring database was used to quantify relationships between demersal fish, epibenthic macroinvertebrates (EMI) and benthic infauna that provide potential pathways for...
Uncertainty in Comparative Analysis with Continuous Nonpoint Source Pollution Models
There have been few attempts to quantify the impact of parameter uncertainty in comparative analysis with continuous nonpoint source pollution models. This paper presents the results of...
A Screening Level Model for Estimation of Vadose Zone Leaching and Saturated Zone Mixing: VLEACHSM
A screening level computer model has been developed for the evaluation of pollutant migration through the vadose zone and subsequent mixing within the saturated zone. The model, called...
Retention-Tank Systems: A Unique Operating Practice for Managing Complex Waste Streams at Research and Development Facilities
The importance of preventing the introduction of prohibited contaminants to the sanitary sewer is critical to the management of large federal facilities such as the Lawrence Livermore...
Modeling SSO's Resulting from Peak Conditions
Miami-Dade Water and Sewer Department (MDWASD) is undertaking the installation and maintenance of a computerized collection and transmission model and peak flow management study. Through...
Design and Construction of the Santa Ana River Wash Crossing of the Inland Feeder
The Inland Feeder Pipeline passes beneath the Santa Ana River in Southern California. The flood plain of the river provides the habitat for two endangered species and to avoid surface...
Non-Federal Flood Control Works Inspection Program
This paper presents a general description of the Non-Federal FCW Inspection Program and results obtained from the evaluations already completed. A discussion of the GIS package for data...
Border Environment Cooperation Commission: 1995 Year End Status Report
1995...What a year! The Border Environment Cooperation Commission (BECC) opened its doors in February 1995, to lay the foundations of the organization whose purpose is to identify, develop,...
