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...
Update: Bridge Scour
Nearly 500 bridges have failed because of hydraulic conditions�primarily scour�since 1950, but the collapse of the Route 90 bridge over Schoharie Creek in April 1987 focused national attention...
Corrosion Below: Sewer Structures
When a sewer system fails, the cause is often not the pipe but a manhole, junction or other special-purpose structure. Most of these structures are concrete, either cast in place or precast....
Yazoo River Basin a New Direction for the Corps
The paper presents the lessons learned from the past events in the Yazoo Basin. The Yazoo Basin project is the only mechanism available that can provide the flood control that is needed...
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...
Seismic Surgery Rewarded
By installing isolators in the columns and strengthening the frame, engineers upgraded an eight-story concrete office building in Seal Beach, Calif. so that it should continue to function...
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...
Seismic Hazard Along a Crude Oil Pipeline in the Event of an 1811-1812 Type New Madrid Earthquake
This paper presents an assessment of the seismic hazard that exists along a major crude oil pipeline (pipeline 22). An 1811-1812 type New Madrid earthquake with moment magnitude 8.2 is...
Aseismic Calculations for Transmission Towers
In this paper, mechanical models for long-span transmission line systems under elastic and gravitational restoring forces are established in three different directions; this continues...
