Education and Continuing Development for the Civil Engineer
Setting the Agenda for the 90's and Beyond
The 1990 Forum Proceedings is a collection of papers that were written to provide a basis for deliberation and conclusions at the ASCE 1990 National Forum on Education and Continuing Development...
The Great American Pyramid
For more than 50 years officials of Memphis, Tenn. have wanted to establish a link to their Egyptian namesake--and they will, through a pyramid. As opposed to its Egyptian forerunners,...
On the Drawing Board
Reliable and quantitative nondestructive evaluation (NDE) methods for construction materials of wood, concrete, masonry and structural steel are needed. NSF program director John Scalzi...
Bridges Under Surveillance
Although bridge monitoring is still in its infancy, research, pilot studies and field work are underway across the country. While today it's still a pie-in-the-sky goal, the...
Behavior and Design of Gravity Earth Retaining Structures
This paper summarizes recent research on the soil-structure interaction of gravity earth retaining structures and provides new design procedures for these structures. The procedures currently...
Management of Groundwater Overdraft in the Phoenix, Arizona, Area
By law, the overdrafting of groundwater in the Phoenix, Arizona, area must cease by the year 2025. Safe yield can be achieved by means of conservation, water supply augmentation, and condemnation...
Biodiversity in Riparian Communities and Watershed Management
Riparian communities are demonstrated to be regional centers of biodiversity and biomass. Examples are taken primarily from bird and lizard communities in the Southwest, since these vertebrates...
Sprinkler System Design for Frost Protection
Both undertree and overtree systems for frost protection by sprinkling are currently being used. The criteria based on experimental results and theoretical modeling have been reviewed...
Design of Steel Transmission Pole Structures
Deadly Debris Flows on I-5 Near Grapevine, CA
A series of debris flows inundated the southbound lanes of interstate Highway 5 (1-5) approximately 110 km (70 mi) NW of Los Angeles, California, between Fort Tejon and Grapevine, early...
Evolution of Drainage Criteria, Albuquerque, New Mexico
Storm drainage in Albuquerque, NM is a central issue in land development. To expedite municipal development while assuring public safety and preserving environmental attributes in a public...
Expanding Groundwater Production in Southern California
The incentive to achieve greater conjunctive use in Southern California has been provided by the Metropolitan Water District of Southern California through a special pricing mechanism...
Multiple Phenomena of Debris-Flow Processes: A Challenge for Hazard Assessments
Hazardous hydraulic processes associated with arid environments commonly repesent significant risks to the safety of the public. However, the public generally considers these risks to...
Recurrence of Debris Flows on an Alluvial Fan in Central Utah
In the spring of 1983 a large debris flow occurred in the drainage of Birch Creek, near Fountain Green in central Utah. During the debris-flow activity, a new channel was incised into...
Structural Control of Ground-Water Induced Debris Flows
A number of case studies have attributed debris flow initiation to the effect of elevated pore pressure from a bedrock ground-water source. Debris flows on slopes underlain by Precambrian...
Application of Geological Information to Arizona Flood Hazard Assessment
Hydrological modeling procedures applied to regulatory flood-hazard zonation can be misapplied when assumptions concerning flood-hazardous processes are violated. Geomorphological mapping...
Prediction of Debris Flow Prone Areas and Damage
It is very important when drawing hazard maps to estimate damage to houses from debris flow of certain fixed quantities. A debris flow disaster, which occurred in Kake Town, Hiroshima...
A Value Engineering/Risk Analysis Approach to Operation and Maintenance of Hydraulic Structures
Value engineering is an objective, systematic method for minimizing cost of a system. Risk analysis is a method of quantifying uncertainties or probabilities of possible economic loss,...
Risk Analysis as a Tool to Determine Spillway Design Capacities
Lyman Dam is an earth and rockfill structure located on the Little Colorado River approximately 11 miles south and upstream of St. Johns, Arizona. Several studies examining the safety...
