Usefulness of Low-Cost Watershed Monitoring: A Case Study
A one-year monitoring study was conducted for Harford County, Maryland to identify water quality problems and sources in the 98 mi2 Bush River watershed....

Implications of Design Uncertainty in Benefit-Cost Analysis

Delineation of Voids Beneath Highways in Massachusetts

A Decision Support System for Dredging the Lower Mississippi River
The paper describes a decision support system proposed to aid short-term scheduling of maintenance dredging activities on the lower Mississippi River for the New Orleans District of the...

Applying Benefits-to-Costs Analysis for Stormwater Improvement Projects
Benefit-to-cost analyses provide a measure of evaluation for the justification, selection, and prioritization of stormwater improvement projects. Facing increased competition for tax dollars...

Integrating Water Conservation Into Water Supply Planning
Consideration of water demand reduction strategies is increasingly important in water resources planning. Although more research is needed to improve the reliability of water savings data,...

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...

Observations of Microcracking and Pore Collapse in Limestone Using Liquid Metal Porosimetry
A technique has been developed to preserve and observe the microstructure of rock or other porous material, as they exist under stresses, using liquid metal porosimetry. Cylindrical specimens...

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...

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...

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...

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...

Hydro Plant Modernization and Uprating
The paper suggests that the method to achieve desirable hydropower benefits at costs lower than for new thermal projects, is through systematic modernization and upgrading of older hydro...

Direct Load Cell-Based Weighing Lysimeter System
A low-cost weighing lysimeter system is described which is capable of measuring evapotranspiration with an accuracy of 0.05-0.10 mm. A two-lysimeter system with electronic data logger...

Construction under Fire
Construction is not carried out in a laboratory setting under controlled conditions—especially in areas of socio-political conflict, such as El Salvador in the 1980s. Instead, the construction...

The Marina Environment from a Boaters Point of View
A discussion of the benefits and problems encountered by the recreational boater as a tenant of both the public and private marinas in Southern California is presented....

Design and Construction of Boat Launching Ramps
Although boat launching ramps are not 'high tech' facilities compared to many other types of waterfront construction, there is a continuing void of knowledge,...

A Stratified Percolation Model for Saturated and Unsaturated Flow Through Natural Fractures
The geometry of the asperities of contact between the two surfaces of a fracture and of the adjacent void spaces determines fluid flow through a fracture and the mechanical deformation...

Concrete Cask Storage Technology
The paper presents the design and operation of the new dry storage system for nuclear waste. The system was designed by complete nuclear, thermal-hydraulic and structural analysis to the...

Requirements for Controlling a Repository's Releases of Carbon-14 Dioxide; The High Costs and Negligible Benefits
A repository excavated within the unsaturated zone may release carbon(C)-14 dioxide in amounts that exceed limits imposed by the Environmental Protection Agency (EPA) and the Nuclear Regulatory...
