Three primary qualities are necessary for effective negotiation: knowledge, attitude, and skill. The author's firm has successfully used a negotiating team approach. This...
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...
A Tale of Six Cities
Battle Creek is a four mile urban stream that had an erosion problem that was accelerating with urbanization of its watershed. Erosion created unstable ravine slopes over 60 feet high,...
Innovative Strategies to Improve Urban Transportation Performance
The field of urban transportation is facing some severe challenges. Roadways continue to deteriorate, the financial condition of public transit systems is abysmal, and general productivity...
Reshaping the Future of Plastic Buildings
Plastic structures have been around for 40 years, but have for the most part been showcases with little use in the mainstream of the building industry. To be used effectively, plastics...
Personal Computers and Stormwater Management Programs
Urban flooding and drainage problems are the result of complex interactions between natural and man-made systems. Comprehensive analysis of the hydrologic characteristics of these problems...
Use of Spreadsheets in Stormwater Modeling
The use of microcomputers is becoming more and more prevalent in both large and small design offices as their first cost continues to decrease, as their capabilities continue to increase,...
Design and Operating Rules for Reservoir Storage to Offset Future Consumptive Use
The Washington Metropolitan Area (WMA) relies largely on the Potomac River for water supply. After many years of study, a coordinated regional operating plan was adopted by the water supply...
Groundwater Models: Converting Research Developments into Practical Applications
One method of bridging the gap between code developer and code applier is through separate user-friendly computer programs called preprocessors that prepare data before execution of the...
Modeling a Water Distribution System
Problems encountered in modeling the water distribution system for the City of Norwich, NY are discussed and the procedures used to solve each problem are described. The interpretation...
Water Data Bank of the Hashemite Kingdom of Jordan
The Hashemite Kingdom of Jordan and the United States of America have jointly undertaken an investigation of the ground-water resources of Northern Jordan. An initial step in the investigation...
Real Time Control of Combined Sewers
After an introduction on the scope of urban drainage and water pollution control problems static solution approaches are shortly described and their disadvantages are lined out. The potential...
Integrated Design Methodology for Urban Stormwater Detention Facilities
The objective of this paper is to present the core of a design methodology that avoids the pitfalls of the design storm concept by using a microcomputer algorithm to estimate the long-term...
Practical Water Demand Forecasting
The authors describe their experience in designing, building, and applying a water demand forecasting model for the Denver metropolitan area. In the presence of incomplete and sometimes...
Future Trends in Software Development
The Office of Water (OW) has set program goals of improving the productivity and technical quality of wasteload allocation modeling and water quality-based permitting in the States and...
Study of Stochastic Planning and Design of Multireservoir Systems
