Optimizing Urban Ground Water Supply Systems
The cost of Pumping comprises a major part of total water operation and maintenance expenses. Most utilities attempt to keep these costs down. However, there are areas of study that may...

A Decision Support System for Water Supply Costing
Accurate cost estimates for water supply system expansions are an important component of the planning process. A spreadsheet-based cost estimating model called SWFCOST was developed as...

Poisson Instability of Laminated Composite Plates
The paper considers the uniaxial buckling of rectangular, anisotropic composite laminates with in-plane restrained unloaded edges where Poisson's effect is predominant to...

A Community-Focused Routing and Siting Model for Hazardous Materials and Wastes
A model is presented that shippers, carriers and policy-makers can use to analyze routing problems for hazardous materials or routing-and-siting problems for wastes. Unlike many other...

Surviving the Storm: Building Codes and the Reduction of Hurricane Damage
The link between adequate building codes, enforcement, and the level of damage experienced in major hurricanes was examined in a 1989 study by AIRAC, a public policy research group sponsored...

Radical Environmentalism, The New Approach: The Removal of Oil as a Primary Goal of Oil Spill Clean Up
In this paper the author examines the alternative methods of abating a catastrophic oil spill and compares these methods to the controlled burning of an oil spill using a fire-resistant...

Views of Environmental Issues Among Port Managers
Prior to the environmental movement, port operations were regulated, but clearly not as much as they are today. This study examines the impact of environmental regulation from the perspective...

Evaluating Shoreline Protection Alternatives
Continued erosion of the shoreline results in loss of land, depreciation of property values and may result in an increased threat to public safety. Limited financial resources require...

Coastal Maintenance?The Netherlands
The government of The Netherlands decided in the summer of 1990 to maintain the coastline at the position of 1990. This will be done mainly by artificial beach nourishment. The costs will...

Waste Water Disposal from Coastal Communities Economic and Environmental Consequences of Green Politics
As a result of increasing pressure from the European Commission and environmental groups the UK Government announced, in March 1990, that it would no longer allow the discharge of untreated...

Permit Compliance Programs for Large Scale Development Projects
California Assembly Bill 3180 requires that the implementation of environmental mitigation measures be monitored for compliance during project development. Permit compliance programs for...

An Engineering Evaluation of Fine Sedimentation at the Mayport Naval Basin, Mayport, Florida
The Mayport Naval Basin is located near the mouth of the St Johns River in northeastern Florida, U.S.A. A total of 16.8 million cubic yards of fine sediment were dredged from the harbor...

Optimization of Maintenance for Coastal Inlets with Uncertainty
Maintenance dredging costs the nation roughly $400 million per year. Yet, relative to other areas of water resources engineering, little attempt has been made to apply operations research...

Chesapeake Bay Field Modeling and Monitoring Projects
'Traditional' erosion control measures often do not meet the Corps of Engineers' requirement for economic justification. The costs of these measures...

Composting, Past, Present and Future
Over the past ten years, the composting process has taken on a different look as a method of processing municipal sludge. Today it is one of the most popular and prevalent methods of sludge...

Crossflow vs. Counterflow Air Stripping Costs
Crossflow towers offer a potential economic advantage over counterflow towers due to savings in fan power costs as well as material costs. These savings increase as contaminant volatility...

Environmental Protection, Resource Allocation and CERCLA: A Practitioners Perspective
In accepting Superfund's mandate of protection of human health and the environment in a timely manner, critics often overlook, the limited human, technical and material resources...

Probabilistic Analysis of Modernization Options
Benefit-cost analysis is a standard procedure for reaching planning decisions. Cost overruns and benefit shortfalls are also common occurrences. One reason for the difficulty of predicting...

Evaluating the Dynamic Operating Benefits of Hydro Power Plants
In 1986, the Electric Power Research Institute asked Decision Focus to develop a new planning model to quantify the dynamic operating benefits of power technologies that offer operating...

When FERC Investigates Your Unlicensed Project: A Five-Point Protection Plan
A FERC investigation into a project's jurisdictional status poses the potential for substantial risks and costs. This paper outlines a 'five-point protection...
