Environmental Engineering
The American Society of Civil Engineers annually sponsors a Specialty Conference on Environmental Engineering. The 1987 Conference was held in Orlando, Florida on July 7-9, 1987 with cooperation...
A Burning Wasteland Reclaimed
Until recently the PJP Landfill exemplified what can happen when uncontrolled and illegal dumping goes on for many years. Now it is an example of what innovation and imagination can do...
Cleanup on a Large Scale
The San Gabriel Basin yields 200,000 ac ft of groundwater a year from 400 supply wells. This water makes up 95% of the Valley's water supply. Already 30% of the water pumped...
The Use of Microcomputers to Perform Airport Emission Inventories
The authors found the use of LOTUS 1-2-3, a microcomputer spreadsheet package that permitted easy calculation of emissions and easy revision of data for studying options in aircraft types,...
Land Application of Wastewater Sludge
Prepared by the Task Committee on Land Application of Sludge of the Committee on Water Pollution Management of the Environmental Engineering Division of ASCE. ...
Another Geotech Import: Deep Soil Mixing
A technique called deep soil mixing (DSM), imported from Japan, has been used to stabilize an existing dam foundation. When the Bureau of Reclamation discovered that Jackson Lake Dam had...
Maximum-Slew-Rate Nonlinear Control for Improved Transient Response in Hydrogenerators
This paper considers a linearized model for fixed blade turbines. This paper demonstrates that constant gate speed bang-bang control holds potential advantages over current control techniques....
Planning for Hydro Projects in an Integrated System
The Incorporated County of Los Alamos, New Mexico (County) is forming an integrated electric utility system to serve the combined loads of the County and the Los Alamos National Laboratory...
First Impulse Turbine in the U.S. Mining Industry
The United States Bureau of Mines has funded a research project to investigate the improvements made in the operation of mine refrigeration systems when a thermal energy recovery system...
Operation of the Annapolis Tidal Straflo Unit
The Annapolis Tidal Generating Station, located at Annapolis Royal, Nova Scotia, is the first plant in North America to generate electricity by Tidal action. The facility, rated at 19....
Valuation of System Hydro Additions
The purpose of this paper is to examine the major factors and steps which affect the valuation process of adding hydro power plants to an integrated hydro-thermal generation system. Results...
Economic Evaluation of Alternative Electric Power Developments
A hydroelectric-dominated power system and a thermal-dominated system represent different ways of meeting total electric demand, but with materially different cash flow patterns. This...
Gas Bubble Disease in Trout Below a Low Dam
Research and efforts to reduce nitrogen supersaturation which is affecting trout in the Bighorn River, Montana, below Yellowtail Afterbay Dam is described. Nitrogen supersaturation can...
Design of Tension Member Insulated Anchor for Arctic Pipelines
This paper explores the latest development in above-ground waterflood pipe anchors currently being used on the SOHIO operated portion of the Prudhoe Bay Oil Field. The objective of the...
Design and Monitoring of an Ice Drill Pad
An ice pad was sucessfully designed and built to provide a suitable foundation for an exploratory drill rig in the National Petroleum Reserve of Alaska in early 1985. Design considerations...
A Self-Refrigerated Gravel Pad Foundation for Large Thermal Loads
Design criteria for a proposed power plant at Thule Air Force Base, Greenland, involved both large thermal loads from the diesel engines and large static loads from an eight foot thick...
Development of a Self-Heating Thermal Probe for Saline Permafrost
Geothermal modelling and prototype testing are described to support the development of a self-heating thermal probe. This has application for in-situ determination of the amount of unfrozen...
Ground Temperature Monitoring Cominco's Red Dog Project
Procedures are available in the literature for estimating subsurface thermal characteristics of foundation soils in cold regions using published climatic characteristics for a given area....
Long Term Performance of the Goldstream Creek Bridge
In 1964 the Alaska Department of Transportation and the U. S. Army Cold Regions Research and Engineering Laboratory initiated a cooperative study which in the long-term generated a significant...
A Thermal Analysis of Pavement Thawing
This research focuses on identifying the spring thawing period for the purpose of timing load restrictions on low to medium volume roads in frost-susceptible areas. Cases evaluated include...
