Seismic Solutions for Steel Frame Buildings
After the Northridge Earthquake, damage in steel moment resisting frame connections stunned engineers. Now those engineers are scrambling to find and test new kinds of connections. This...
An Extended Relaxation Technique for Unsteady Flows in Networks
A recent enhancement to the FLD WAY model is the addition of an extended relaxation technique for modeling unsteady flows in a dendritic (tree-type) network of channels with tributaries...
Pier Width and Local-Scour Depth
Presented here are the results of an enquiry into the effects of pier width on local scour depth. The results show that scour depth does not scale linearly with pier width unless there...
An Analysis of Characteristics of Basset Force on Particles Accelerating in Arbitrary Flow Field
In present study of solid-liquid two phase flow, the effect of Basset force on a particle moving unsteadily in a non-uniform flow is not very clear. For this reason, the properties of...
Dynamic vs. Quasi-Static Effluent Limits
Selenium water quality objectives are currently being exceeded in the San Joaquin River, California due to agricultural subsurface drainage discharges. The Federal Clean Water Act requires...
Rethinking Well Efficiency
Many authors have suggested ways to evaluate water well efficiency. Most of these have either compared some form of measured drawdown with theoretical drawdown or measured the fraction...
Salinity and Hydraulic Issues at a Constructed Wetlands
A constructed wetlands at Boulder City, Nevada was designed to use effluent pumped from the City's wastewater treatment plant. The design was complicated by the highly permeable...
Debris Flow Events at Mountainous Creeks near Santiago, Chile- Hydrologic Analysis
One of the most important aspects in relation to peak flows magnitudes generated in mountainous catchments at the western side of the Andes facing the city of Santiago, Chile (latitude...
A Process Unit Based Approach to Media-Integrated Waste Minimization: A Paint Manufacturing Case Study
Research conducted at the School of Engineering, University of Guelph, has developed a media-integrated waste minimization plan for a major Ontario paint and coatings manufacturer. The...
Glacier-Generated Floods and Debris Flows
Sudden release of glacially impounded water causes catastrophic floods, known as outburst floods, and ocasionally spawn debris flows that pose significant hazards in mountainous areas....
Physical Modeling to Determine Head Loss at Selected Surcharged Sewer Manholes
The head losses at sewer pipe junctions (manholes) under surcharged conditions were measured in a 1:6 scale model of a typical manhole with one main line passing through it and two perpendicular...
From Sediment to Solid
While closing a 32 acre, storm-water impoundment area contaminated with petroleum waste sediments at an oil refinery, engineers came up with a more-effective treatment plan that saved...
Rapid Slope Monitoring
Use of inexpensive coaxial cable rather than inclinometers has cut the cost of monitoring slope movement at seven potential landslide sites in California. The method involved is called...
Engineering Mechanics
This proceedings contains keynote and summary papers presented at the 11th ASCE Engineering Mechanics Conference held in Fort Lauderdale, Florida, May 20-22, 1996. The keynote papers address...
Building a Landfill on Mud(Available only in Geo/Environmental Special Issue)
In the early 1980s, officials at the Delaware Solid Waste Authority (DSWA) thought they had found the ideal site for a new municipal landfill: low acquisition cost, direct access from...

The Northridge Fractures: Are We Learning the Right Lessons?
After the Northridge earthquake in January 1994, engineers found problems with special moment-resisting frames. There were multiple facture modes, and typical damage involved primary crack...
Northridge Postscript: Lesson on Steel Connections
Immediately after the Northridge earthquake in January 1994, the general concensus was that steel-framed buildings performed extremely well. Later, inspectors were surprised to find weld...
