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...

Spreadsheet Applications in Water Quality Management
The state regulatory environment requires simple, quick, easy to use and maintain water quality analysis tools. Therefore, for the evaluation of toxic substances, a new approach towards...

Conjunctive Use Study of Groundwater and Surface Water in Chino Basin, California
The purpose of this paper is to study the effects of artificial recharge on an already contaminated unconfined aquifer and propose optimal recharging and pumping schemes to prevent the...

Sewer Rehabilitation?Metro Chicago
After a number of public hearings in the late 1960's and early 1970's which focused on sewer backup problems in the Sanitary District's separate...

Rehabilitation Strategies for Urban Drainage Systems?A European Perspective
Rehabilitation of urban drainage system is needed in many old European cities. This is in part due to the required structural upgrading of the existing sewerage system. But rehabilitation...

Trends and Emerging Issues: A Longitudinal Study of Government Agencies' Perceptions of Great Lakes Water Resources and Related Issues
The perceptions of government agencies with jurisdiction over Great Lakes' shoreline has changed over time with respect to important issues related to water quality and a...

The Remedial Action Plan for the Fox River, Wisconsin
The nature of and need for Remedial Action Plans (RAP) in 42 areas of the Great Lakes is reviewed with special attention given to the Fox River and Lower Green Bay area. A brief historical,...

Leachate Flow Through Landfills
The problem of estimating the amount of leachate generated in a landfill site is of significance in the assessment of potential environmental impacts. Although there are a variety of regulations...
