Simulation of Airborne Snow Water Equivalent Measurement Errors Made over a Forest Environment
The Office of Hydrology of the National Weather Service has developed and maintains an operational Airborne Gamma Radiation Snow Survey Program in the upper Midwest (Peck, et al. , 1980)....

Snow Management Practices for Increasing Soil Water Reserves in Frozen Prairie Soils
It is demonstrated that stubble management practices can be used to increase snowcover accumulations in the Canadian Prairies. However, the potential for significant increasing soil water...

Snow Management at Ski Areas: Hydrologic Effects
Several types of snow management are practiced at downhill ski areas. Each of these activities has a variety of hydrologic consequences. The extent to which these management practices...

Prediction of Soil Water Properties for Hydrologic Modeling
Water flow in soils can be characterized for many boundary and initial conditions by solving governing differential equations. Thus, a physically consistent means of quantifying water...

Closed Negotiations?Out with the Poker Players
The paper describes the closed negotiation process employed by one owner/client, the U. S. Army Corps of Engineers, in procuring firm, fixed price design service contracts. Although not...

Silent Negotiations: Listen with Your Eyes
More than sixty per cent of all communication is non-verbal. The impact of body language during negotiations can be either positive or negative, depending on the negotiator's...

Avoiding Lengthy and Costly Litigation by Negotiating Alternative Dispute Resolution Methods
A 'hot issue' in the construction industry today is the negative aspects perceived from wide arbitration use over the last 15 years. Although hearings usually...

Techniques of Negotiation
Three primary qualities are necessary for effective negotiation: knowledge, attitude, and skill. The author's firm has successfully used a negotiating team approach. This...

Embankment Seepage Control Design and Construction
For seepage control features of embankment dams, design criteria and construction practice is reviewed as it is reflected in the experience of the U. S. Army Corps of Engineers. The generally...

A Case History of Leakage from a Surface Impoundment
A manufacturing company constructed a 48-acre (19 hectare), unlined surface impoundment at a site in northern Texas to store wastewater. The site is underlain by unsaturated, alluvial...

Application of a Three-Dimensional Coupled Finite Element?Boundary Element Method
Three-dimensional conditions in underground construction occur at the face of a tunnel, at intersections of underground openings and around roughly equidimensional openings. As long as...

Probability of Stability Design of Open Pit Slopes
Uncertainty and risk have always been associated with mining. This is evidenced in the common mining terminology of proven ore, probable ore, and possible ore. From a geotechnical standpoint,...

Probability Applied to Slope Design?Case Histories
A major problem encountered with the choice of an appropriate value for the design probability. Initial experience, obtained during open-pit investigation, suggested that slope geometry...

Prediction of Highway Construction Noise Levels
A model for the prediction of noise levels from highway construction operations has been developed under sponsorship of the Federal Highway Administration (FHWA). Noise sources are geometrically...

Noise and Air Blast from Construction Blasting
Noise generated by construction blasting differs from other construction noise because of its frequency content. The audible high frequency portion is accompanied by a non audible, lower...

Cost Assessment of Construction Noise Control
The results of a series of studies have provided noise control engineers with a method to estimate off-site construction noise levels and the cost of reducing these to acceptable levels....

Highway Noise: FHWA Requirements and Barrier Design
Since 1973, the Federal Highway Administration (FHWA) has required noise studies for nearly all proposed roadways and roadway improvements that receive federal aid. An overview of these...

Noise Characteristics of Alternative Urban Transit Technologies
The noise characteristics of alternative transit technologies for an urban area are summarized. Among the transportation technologies considered are a busway system, light rail transit...

Noise Assessment, Measurement, and Mitigation, an OSHA View
A discussion is presented on the Occupational Safety and Health Administration (OSHA) 29 CFR 1910. 95 General Industry noise exposure standards and the 29 CFR 1926. 52 and 1926. 101 Construction...

Cost-Effective Design of Practically Vibration-Free High-Technology Facilities
Advanced electro-optical equipment, such as that used in the production of integrated circuits, requires clean environments with extremely limited vibrations. Ground motions, personnel...
