Multipoint Monitoring
Monitoring groundwater is necessary to guard against pollution and to provide data for water resource management. The Orange County (Calif.) Water District has embarked on a program of...

Legal, Institutional, Financial and Environmental Aspects of Water Issues
The papers included in this publication were presented at the 1989 LIFE symposium and address the legal, institutional, financial and environmental aspects of water issues. These aspects...

The Race for Smart Cars
Prendergast describes the technological elements involved in Intelligent Vehicle/Highway Systems (IVHS), current programs in Europe, Japan and the U.S. aimed at implementing IVHS systems,...

Post-Audits of Environmental Programs and Projects
This is the proceedings of a session at the ASCE Convention, New Orleans, October 1989. Post-audits include evaluation, assessment, and audit of the effects, both intended and unintended,...

Resident Engineering Costs vs. Construction Costs for New York City Water Pollution Control Projects
This paper begins by describing the New York City fresh water system, water pollution control plants, and the development of capital programs. It then discusses contracting methods, construction...

Augering Answers
Leaking storage tanks, a long time environmental problem, are now being addressed nationally with cleanup regulations. Clearly, inexpensive and quick remediations are needed. This article...

Protection of Juvenile Anadromous Fish
Protection of juvenile anadromous fish (salmon, steelhead, etc. ) during their seaward migration is a major concern in the Pacific Northwest. The existing screening structures at the head...

Reservoir Releases Improvements?Requiem for Integrating Pollution Control and Resource Management Programs?
To better define the interrelationships between economic growth and development, pollution control, and water resource management, TVA conducted two studies that examined how reservoir...

Application of Split Roller Bearings in Small Vertical Hydro Turbines
The elimination of lower turbine bearing problems with regard to reliability and water flow contamination was the main concern of this project. A design was needed that would fit the existing...

Hydro Machinery Problem Solving Experiences
Within the last decade the use of modern data acquisition instrumentation and techniques have moved the subject of the machinery problem solving into a more scientific arena. This paper...

Regulatory and Environmental Issues of the Chisman Creek Superfund Site
This paper discusses the regulatory and environmental issues arising from the response to the Record of Decision (ROD) for the Chisman Creek Superfund Site in York County, Virginia. Field...

Evaluation of Air Quality Methods in the Asbestos Work Area
Air monitoring is a technique that is routinely used to measure the level of asbestos in a given airspace. This technique has changed significantly since its first use in the asbestos...

Professional Liability on Asbestos Abatement Projects
When the engineer is retained on an asbestos abatement project, he or she must bring to the job and employ that degree of skill and learning ordinarily exercised in the profession in similar...

Random Vibration of a Discrete-Distributed System
The stationary response of an arbitrarily complex, classically damped discrete-distributed system subjected to stationary Gaussian white noise is derived. For certain excitations, the...

Characteristics of Nonstationary Response of Linear Systems
A new formulation for the statistics of the response of linear systems to nonstationary excitation is developed. Both the process and its envelope are examined and exact statistics are...

Irrigation-Induced Contamination Problems
At the Kesterson National Wildlife Refuge in the San Joaquin Valley of California, severe fish and wildlife problems (waterfowl mortality, embryonic deformities, and reproductive failures)...

Extent of Water Quality Effects of Dams?A National Viewpoint
An overview of phosphorus impacts on impoundments, a subset of the contents of the Dam Water Quality Report is presented. The U.S. Environmental Protection Agency (EPA) is the lead investigator...

A Simple Nonpoint Source Groundwater Quality Management Model
A model is examined which efficiently produces information required by decision makers to assess water quality tradeoffs associated with alternative groundwater protection strategies,...

Assessing WQ Impacts Using a Hydraulic Model
Engineering projects may cause water quality impacts in estuarine systems. It is important to assess those impacts during the planning phase of the project so that mitigation measures...

Mass Transport Modeling of Pearl Harbor
The U.S. Navy is planning to implement the use of organotin antifouling paints into the fleet. Such paints are already in use by commercial vessels and private pleasure crafts. As part...
