Private Coastline Conservation Management: The Land Trust in the San Juan Islands, Washington
Waterfront land values in prime recreation areas like the San Juan Islands are very high. Local, state, and federal agencies have scarce resources for conserving the natural beauty of...

Economic Analysis Tools for Differential Inflation
Economic decisions based on a life-cycle analysis should consider differential increases or decreases in operation and replacement costs and benefits over the project or component life....

Review of the Lake Andes-Wagner Project Sizing
Benefit-cost analyses of the proposed U. S. Bureau of Reclamation Lake Andes-Wagner Project have shown the project to be marginally feasible. In an effort to improve the benefit-cost ratio,...

SCT's Experience with Automated Fleet Management
Sonoma County Transit's (SCT) fleet maintenance program covers all aspects of repair and preventive maintenance, with the exception of major body work. This paper describes...

Procedures for Evaluating TSM Projects
The constraints of limited funding, increasing demand and environmental impact have led to an increase in Transportation Systems Management (TSM) improvements on surface transport systems....

Economic Analysis of Highway Safety Projects
The most commonly used economic analysis for highway safety projects is the cost-benefit ratio. While this is a valid analytical tool, it must be used correctly to produce valid results....

Benefit Cost Analysis of Highway Safety Improvements

Evaluation of Safety Alternatives by Benefit/Cost Analysis
There is an increasing awareness of the need to use limited highway safety funds on projects that offer the greatest benefits. This paper describes the development and application of a...

Shoulder Rumble Strips at Narrow Bridges
The highways in the United States have thousands of minimum design narrow bridges. Replacement of these bridges with current state of the art designs is not cost effective nor feasible...

Tallying Water Resources Goals
Federal water resources planning philosophy has undergone a lengthy evolution with a number of refinements in the past decade to encompass environmental laws and the political philosophy...

Benefit-Cost Evaluation of Minimum Instream Flows
In many cases, determinations of minimum desirable instream flows (MIF) are made without full consideration of economic costs and benefits. Benefits are frequently quantified in nonmonetary...

The Risk Factor in Water Resources
Risk is inherent in nature and society, while uncertainty depends on investigations. Decision making in water resources is most often a deterministic selection of dimensions which divide...

A Breakthrough in Training Construction Inspectors
The Bureau of Reclamation has developed a self-paced, job site focused, three level training program that encompasses the full range of construction inspection skills, knowledges, and...

Excellence in Inspection
Excellence in inspection starts with proper interpretation of specifications and drawings. There exists a void between the design team and the field people which must be bridged in order...

Grouting a Sand Dam
Hardy Dam, owned by Michigan's Consumers Power Co., was constructed in 1929 by dumping sand from railroad trestles for an embankment to support a concrete core wall. Some...

Blue Marsh—A Modular Hydroelectric Project
The Blue Marsh Hydroelectric Project will be the first complete application of concepts developed in several research studies of modular hydroelectric power plant components. The Department...

Design and Test of Cold Formed Steel Members
Latticed systems represent the most spread and low-cost solution for electrical trasmission towers, when ground conditions do not affect the design choice. Steel angles have been used...

Reinforced Roads Bridging Voids
A mathematical model was developed to design a pavement section reinforced with a geotextile or related product to span a void. A full scale field test was conducted to verify the model....

Managing the Highway System
There is a general feeling that increased emphasis on highway management is a promising approach to dealing with a series of apparent issues and trends: The inflating costs of substantial...

Picture Index for Field Verification of Crop Coefficients
A picture index has been developed for eight irrigation crops to obtain reliable, rapid, and low-cost field determinations of crop growth stages and corresponding crop coefficient (Kc)...
