Federal Cleanups: Good News from Bad
Since the end of the Cold War the news about the Department of Energy has been grim: Thousands of acres poisoned with radioactive and toxic wastes, massive cleanup cost overruns due to...

Breaking Wave Measurement by a Void Fraction Technique
Breaking of steep surface gravity waves in seas under moderate to strong wind forcing always involves the entrainment of air into the water column below the air-sea interface. As such,...

Cost Considerations in Planning Pier Terminals
The deregulation of the air transport economy is gradually leading to the involvement of private developers in airport terminal financing. Even the airports run by government agencies...

Optimal Groundwater Reclamation with Captial Costs
A dynamic optimal control model for groundwater remediation was extended to incorporate treatment facility capital costs. Incorporation of the capital costs had the greatest impact on...

Aquifer Remediation Design: Nonlinear Programming and Genetic Algorithms
Nonlinear programming and genetic algorithm solutions of a pump-and-treat aquifer remediation design model are presented and discussed. These models find the minimum cost design of the...

Arizona Groundwater Management Alternatives
Sustainable groundwater management policies are examined through the use of a hydrologic-economic impact model of Arizona surface and groundwater use. Present water use practices were...

Effectiveness of Retrofit in Multi-Family Apartments
This paper reports the results of an evaluation research study of the cost-effectiveness of water-conserving, residential retrofit plumbing devices. By means of a 'quasi-experimental,'...

Designing Under Uncertainty When We Can Reduce Uncertainty: When is Another Observation Worth the Cost?
A method is presented that optimizes the selection of sites for observation of an uncertain parameter when that parameter is used in the risk-based design of an engineered system. The...

Water and Wildlife Enhancement with Land Retirement
This case analysis compares costs of land retirement and current on-going structural improvements for salinity reduction in the Colorado River. Results suggest land retirement programs...

The Economic Cost of Stocking Catchable Rainbow Trout
States annually stock about 20 million pounds of catchable trout in public waters. Complete information on cost is essential to help wildlife agencies make operating and planning decisions....

Activity Based Costing in Water Resources Management
This paper examines the relatively new accounting tool, Activity Based Costing (ABC), and describes its potential application in water resources planning, management, and operations. The...

Development of Missouri River Navigation Analysis
The navigation analysis for the Master Manual review examined mainstem reservoir regulation alternatives by evaluating the benefits of reservoir releases for barge transportation. Navigation...

Lesson Learned form Implementing M&I Optimal Water Delivery
Few municipal water delivery systems are truly optimized to deliver a quantity of water at the least cost. Both the University of Kentucky and Memphis State University have attempted to...

Setting Competitive Water Reuse Rates
Palm Beach County Water Utilities Department (WUD) is preparing to provide reclaimed water service to several large irrigators near the County's Southern Region Wastewater Treatment Plant...

WATSUP: A Simulation Model for Water Supply Cost and Reliability
WATSUP (Water Supply) is a computer model developed to provide a prototype modeling tool for planners to estimate the costs and reliability of urban water supply systems on a regional...

Opportunities, Constraints and Change in Reservoir Management
Changing hydrologic, economic, social and environmental conditions have focused attention on the opportunities for changing reservoir management. Such change can occur in three areas....

Flood Control vs. Flood Management
For the last 130 years, flood policy in the U.S. has been dominated by the belief that floods can be controlled by structural methods, such as levees, dikes and embankments. These efforts...

How Many Observation Wells Does it Take to Find a Groundwater Contamination Plume?
A Bayesian data worth framework is developed to balance the benefits and costs of data collection. In addition to Bayesian decision analysis, tools from Monte Carlo simulation, numerical...

Construction Expertise Transfer with Knowledge Based Systems
The experience held by a cost estimating engineer is a valuable asset in every construction company. For a reliable cost estimation at the conceptual stage of a building project, the missing...

The Design of a Proactive Cost Feedback System for Construction Project Management
Cost projection in project management requires the adjustment of historical costs to reflect the expected context. Improved cost projections require the incorporation of all relevant contextual...
