Flownets by Computer Graphics
A new method of drawing flownets for determining seepage losses in earth dams is developed. The flow and equipotential lines are drawn by modifying W. Kinzelbagh's method....

Application of Risk Management and Value Engineering Techniques to Evaluation of Water Resources Projects with Special Emphasis on Geological Hazards
The purpose of this paper is to provide: 1) a perspective for identifying and evaluating in comparable terms all hazards at a site; and 2) a means for intelligent decision-making based...

Ship It By GIS
Abkowitz, Cheng and Lepotsky describe a GIS system for routing hazardous materials shipments. The safe transport of hazardous materials is emerging as a significant concern impacting local,...

Implementation of HISAM/HISAFE Microcomputer Programs
The Federal Highway Administration had sponsored the development of two software packages called HISAM and HISAFE. HISAM primarily provides an alternative means to store related accident...

The Small Computer Accident Records System (SCARS)
SCARS was developed to support public agencies in Florida in their efforts to analyze traffic accident records and identify high hazard locations. It is an application of the DBASE III+...

Computer Control of Tunnel Systems
An active Tunnel Surveillance and Control System (TSCS) is generally indicated for long highway tunnels. The TSCS uses a computer system, detection devices and a communication system to...

A Computerized Hazardous Material Incidents Database
This paper reports on the development of a microcomputer database management system for hazardous material incidents that occurred on highways and at fixed sites in Arizona. The objective...

Structural Reliability Through Machine Learning From Case Histories
The development of a management tool for the control of structural safety is described. Artificial intelligence techniques of 'machine learning' are employed...

High Level Radioactive Waste Management 1990
The proceedings of the first annual Conference on High Level Radioactive Waste Management, held on April 8-12, 1990, Las Vegas, Nevada, provides information on the current technical issues...

Sons of Martha: Civil Engineering Readings in Modern Literature
These three stories excerpted from the new book Sons of Martha, compiled by Augustine J. Fredrich and published by ASCE as the first book in a new venture by the Publications Division, introduce the engineer...

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...

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...

Fish Bypass Facilities - Tehama-Colusa Canal
Operation of the canal headworks has proven to be detrimental to migrating fish passing the Red Bluff Diversion Dam. Studies performed for the U.S. Bureau of Reclamation were undertaken...

Environmental Aspects of Water Resources Development
Long-term management of resources requires a comprehensive anlysis of the effects that development and management of one resource may be expected to exert upon other resources. However,...

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...

Numerical Simulation of Mudflows from the Hypothetical Failure of a Debris Blockage Lake Below Mount St. Helens, WA
This paper evaluates the characteristics of mudflow events resulting from the hypothetical breaching of a debris blockage dam using a variety of lake levels and impounded water volumes...

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...
