Wastewater Treatment for Better Environment
Wastewaters from households, industries, and combined sewers are collected and transport to the treatment plant with the effluent commonly disposed of by dilution in rivers, lakes or estuaries....
Identifying Transportation Control Measures: a Straighforward Approach to Identifying Transportation Control Measures to Address Concerns with Air Quality
The 1990 Clean Air Act Amendments (CAAA) exemplify society's increasing environmental concern. Regions not attaining the CAAA requirements must develop methods to reduce the pollution....
High-Speed Railways and Development in Japan
There is a need to develop an environmentally friendly railway in response to society's needs, implement high-speed operations on existing tracks, and develop a high-quality, high-speed...
High Speed Rail Initiatives in Korea
The purpose of constructing a high speed rail on the Seoul-Pusan corridor is many fold: to solve intercity traffic congestions, to save energy, to reduce air pollution, and to make possible...
Pierce Transit's Experience with an Alternate Fuel Compressed Natural Gas January-December 1992
At the end of 1992, Pierce Transit's CNG fleet consisted of 30, 40-foot Orion buses, 19 ElDorado Buses, on GMC 'New Look' bus, one 1990 Chevy Celebrity, and one Collins Shuttle van. As...
Potential Role of GIS in Geotechnical Earthquake Engineering Studies at U.S. Army WES
The U.S. Army Corps of Engineers (USACE) was one of the original developers of Geographic Information Systems (GIS) and continues to be active in related research (U.S. Army Engineer Construction...
Digital Evaluation of Contaminated Sites
This paper introduces digital techniques to evaluate historical maps and aerial photographs in order to detect contaminations on derelict industrial sites. Special attention is paid to...
Survey: Fundamental Pavement Crack Imaging Algorithms
Many algorithms for distinguishing pavement cracks from background noise are based on the geometric characteristics of noise, such as shape and size. The objective of this paper is to...

Whose Risk Is It, Anyway?
Near the now-closed Smuggler Mine in Aspen, Colo. toxic lead sits beneath the grass of area residents' yards. A major portion of soil in the area has lead above the EPA action...
Projects on the Czech List
The Czech Republic's increasing reliance on the European Community as a trading partner has created a need for airports, power plants, an improved telephone system, new highways,...
Doing Business In...Bangkok: More than just Temples
Traffic is the most notorious problem afflicting foreign visitors, though air pollution and the enforcement of building codes (in the wake of a provincial hotel collapse in mid-1993) are...
Rail Revival
Rail transit appears to be on the upswing. More than 30 cities are building, extending or seriously considering new rail-transit systems, according to a recent report from the Regional...
Reassessing the Risk Assessment
Risk assessments should help an engineer determine cost-effective remedies to environmental pollution. Unfortunately, most don't. Most assessments drastically overestimate...
VOCs: The New Effluent
The Clean Air Act of 1990, in addition to many state and local regulations, has officials of publicly-owned treatment works (POTWs) shifting their focus, and funds, to air toxic emissions...
Dynamic Compaction of Nuclear Waste
When ponding, caused by settlement of the original soil cover over low-level nuclear waste buried at the Department of Energy's Savannah River Nuclear Plant near Aiken, S.C.,...
Cleaning Up Chromium
From 1956 to 1985, the United Chrome Products plant in Corvallis, Oregon, took a steady toll on the environment. Leaky plating tanks and the discharge of rinse water into a disposal pit...
Controlling Nitrogen in Coastal Waters
Excess nitrogen in coastal waters is becoming a problem worldwide. Nutrients such as nitrogen come from sewage treatment plants, septic tanks, runoff from fertilizer and animal waste,...
A New Era In Transportation
Its passage into law was about as smooth as a rush-hour traffic jam, but the surprising thing about the new Intermodal Surface Transportation Efficiency Act of 1991 (ISTEA) is that it...
Analog Electronic Simulations of a Nonlinear System
We perform electronic analog simulations of a harmonically forced Duffing oscillator. The addition of noise perturbations of sufficient intensity is shown to induce transitions between...
