Construction Technology/Method Identification and Selection System
The proliferation of construction technology and the characteristics of technology information, such as complexity, interdependency, etc., pose the need for a well-organized technology...
Integrated Cost and Schedule Control Automation
Effective management of construction projects depends on good access to and control of data, especially data pertaining to cost and schedule control functions. Long recognizing the need...
Turbulent Water Aeration: Analytical Approach and Experimental Data
Analytical studies based on the statistical theory of turbulence were carried out in order to identify some relevant parameters which may be associated with the reaeration rate coefficient...
A Simple Empirical Model of Aeration at Navigation Dams
In a study of aeration at 28 dams in the upper Ohio River basin, site-specific least-squares linear regression models were used to describe the dissolved oxygen deficit below each dam...
Theoretical Investigation of Oxygenating Bubble Plumes
Rehabilitation of lakes by oxygenation with air or oxygen plumes has been proven to be biologically feasible. Oxygenating plumes are released from areal sources and the gases are absorbed...
Water Surface Flow and Exchange Induced by a Bubble Plume
Aeration is a common method to increase dissolved oxygen in the water of stratified (or non-stratified) lakes. In this method compressed air is injected at some depth, and gas is transferred...
Steady Turbulent Gas Desorption in Surface Condenser Tubes
A one-dimensional steady two-phase separated flow model in conjunction with the energy and mass transfer equations and an associated turbulent mass transfer coefficient model are utilized...

Ground-Water Modeling Without Fear
Computerized ground-water modeling has leapt from the cloistered laboratory to the field project as more and more programs are written for the personal computer. These easy-to-understand...
Conflict in Water Management of James River, ND
Delivery of water from storage in Jamestown Reservoir to 898 acres of newly developed irrigation along the lower James River by the U.S. Bureau of Reclamation during the drought of 1988...
GIS Plans Wastewater Future
When the Public Works Department began phase 3 construction on Albuquerque, N.M.'s current wastewater treatment plant in 1990, it was time to begin thinking about the next...
Computing in Civil Engineering and Symposium on Data Bases
This proceedings consists of the papers presented at the conference Computing in Civil Engineering and Symposium on Data Bases held in conjunction with A/E/C Systems '91 from May 6-8,...
Out of the Lab...and into the Field?
Materials experts know very little about concrete's basic structure. Now, though, engineers at a research center sponsored by the National Science Foundation are working on...
Earthquake Considerations in Design of the Los Angeles Metro
This paper discusses the earthquake design of the Los Angeles Metro. The design earthquake parameters are presented and discussed in light of the behavior of buried structures subjected...
Bridge Seismic Retrofit Prioritization
This paper describes a mathematical model developed to produce an index by which bridges in a network can be prioritized systematically for seismic retrofitting. The model incorporates...
Regional Risk Assessment of Environmental Contamination from Oil Pipelines
This paper presents a methodology for assessing the risk of environmental contamination from oil pipeline leaks due to earthquakes. Risk is measured both as volume of oil released and...
