Urban Stormwater Quality Enhancement
Source Control, Retrofitting, and Combined Sewer Technology
This proceedings contains the papers presented at the Engineering Foundation Conference on Urban Stormwater Quality Enhancement - Source Control, Retrofitting and Combined Sewer Technology,...
Upgrading Antique Sewers
In a $35 million, four-year program, the Massachusetts Water Resources Authority (MWRA) completely restructed the pumping system serving the sewers under East Boston, Chelsea, Revere and...
Strategic Sanitation Planning
Conventional sewerage has generally been the only method considered for human waste and wastewater disposal in urban areas, both in developed and developing countries. In developing countries,...
The Pros and Cons of Public Education
Today, engineers work for a public that has lost faith in the government's ability to spend money efficiently and to contain pollutants effectively. Many engineers now see...
Transmission Line Structure Loading
This paper outlines specific procedures for determining loads on transmission line structure systems that can be used in the reliability based design or assessment of components of these...
Tripping and Strength of Asymmetrical Plate Stiffeners
Tripping (lateral-torsional buckling) of symmetrical or asymmetrical plate stiffeners can be analyzed by using differential equations or energy formulation. An analytical study is reported...
Load Combinations for LRFD With Wood Construction
Probability based limit states design for wood construction is complicated by the fact that wood is a natural material with large variations in mechanical properties and is sensitive to...
Standards for Design Loads During Construction: An ASCE Effort
ASCE embarked on a new standards activity by the Design Loads for Structures During Construction Standards Committee. The objective of the effort is the development of standard guidelines...
Buying Tomorrow's Water
Cities are finding that selling future access rights to sewer and water treatment plants can get them needed expansion capital. Although the access rights system is similar to development...
Issues in Evaluating Combined Repeated Loading of Deep Foundations
The capacity and load/displacement response of deep foundations subjected to combined modes of repeated loading can be significantly different from the response under single (axial or...
Economic Impacts of Storm Sewer Design Criteria
This paper discusses the selection of storm sewer design criteria and the resulting economic impacts. Using the Rational Method for calculating design flows, an investigation was made...
Urban Stormwater Runoff Management
Local land use regulations managing stormwater runoff in new urban developments are the most practical and effective method to control pollutants in urban stormwater runoff or prevent...
Relief of an Urban Storm Drainage System
The Peaks Branch storm sewer system was designed in the 1930s to drain 5.7 square miles of East Dallas. Subsequently, development blocked the emergency overflow paths and many areas are...
Analysis of Storm Sewers During Surcharge
A mathematical model based on a lumped system approach is presented to simulate unsteady flow in storm sewers during surcharge. The model equations and method of solution are presented....
Siting the New Boston Outfall: Near-Field Considerations
This paper describes a procedure applied in near-field considerations for siting the new outfall to serve the Massachusetts Water Resources Authority's (MWRA) proposed regional...
Big Trouble in Little America
Traditionally, rural communities in the U.S. have relied on septic systems to treat their wastewater. Many of the nation's 23 million septic systems, however, are failing....
Affordable Housing and the Civil Engineer
The Joint Venture for Affordable Housing (JVAH) Demonstration. Program accomplished the goal and reduced the first time cost of housing by up to 30% through the use of innovative methods...
Load Combinations for Codified Design
Loading requirements used in current standards for structural design are not consistent in their conceptual basis, appearance or use. Unified limit states design procedures for structures...
Probabilistic Load Combinations in Nuclear Structures
A variety of loads affect a nuclear power facility during its lifetime. The magnitudes or intensities of these loads are uncertain, and for some of them, their time of occurrence is also...
Outcrossing Rates By Point Crossing Method
The point crossing method is applied to compute outcrossing rates for general safe domains, i.e., nonlinear load combinations problems. For stationary processes the method typically yields...
