Modeling of Coupled Heat-Mass-Stress Effects in Geologic Media
To investigate the importance of coupled hydraulic-thermal-mechanical processes for the potential nuclear waste storage repository at the Yucca Mountain, a computer code is being developed....
Optimal Operation of Multiple Reservoir Systems
In this paper a temporal decomposition approach is presented to solve a long term deterministic model for a multi-reservoir system. Through relaxation the long term problem is broken into...
Stream Standards for Toxics and Irrigated Agriculture Using New Mexico as a Case Study
New Mexico follows a policy of 'antidegradation' with respect to the existing quality of a stream, but its standards specifically exclude return flows from irrigated...
The Colorado River Salinity Program?An Overall Perspective
Economic losses resulting from increases in salinity in the Colorado River system were estimated to be $311 million annually in 1986. As a result of protests by Mexico to the United States...
Drainage Manual for Clark County, Nevada
The development of a flood control district and its associated capital improvement and regulatory programs does not by itself address drainage standards for a community. While the capital...
Can Erosion Control Meet Regulatory Standards?
An erosion control design method for rainfall/surface erosion is presented that enables the designer to determine design loads and the resulting erosion control requirements. Design loads...
Mass Conservation in the RMA2V Code
This paper discusses the RMA2V hydrodynamic code with a particular interest in mass conservation problems. These originate from at least two sources. One of which is the slip flow boundary...
Use of Voluntary Consensus Standards by the Bureau of Reclamation
This paper outlines how the Bureau of Reclamation has historically participated in standards development for emerging technologies, and how present standards are applied or adapted for...
Are ASTM Standards Enough?
ASTM (American Society for Testing and Materials) is most likely the World's most renown developer of voluntary consensus standards. Its standards development process utilizes...
The Fine Print
An engineer who uses software, or supervises those who do, must know the laws regulating its purchase and use. Whether a company contracts for custom software, or leases, licenses or contracts...
Prospects for International Engineering Practice
International trade is growing in construction products and services. It is stimulated by international efforts to reduce technical barriers to trade and the formation of a single European...
Commentary on Building Code Requirements for Masonry Structures (ACI 530-88/ ASCE 5-88) and Commentary on Specifications for Masonry Structures (ACI 530.1-88/ ASCE 6-88)
Grouting Slip Liners: The New Inside Story
There are approximately 800,000 miles of water and sewer pipelines in the U.S. that need remedial work. About 2% need work each year, usually due to normal or accidental corrosion. Normal...

Taming Structural Vibrations
Vibration is a common problem in buildings that contain large spaces and long spans, especially gymnasiums and dance studios. Research shows that people respond more adversely to continuous...
Diatomaceous Soils: A New Approach
Diatomaceous soils are formed over long periods of time when the skeletal remains of plankton and other single-celled marine creatures sink and accumulate in lakes, estuaries and oceans....
Changes in Tubular Design Codes
This paper summarizes a number of changes in design provisions for tubular structures that have recently been adopted. These are the result of a number of research advances concerning...
Concrete Strength-Quality Assurance
The usual criterion for establishing grades of structural concrete is the compressive strength measured in an arbitrary manner on a standardized specimen stored in a stipulated fashion...
Study of Partially Prestressed Beams With Unbonded Post-Tensioning
Test on partially prestressed members with bonded Post-Tensioning started recently. Experimental information regarding partially prestressed members having unbonded post-tensioning is...
Local Wind Pressures on Roofs
The paper reviews the results of the most recent research studies in the evaluation of wind pressure coefficients for the design of roof cladding elements. The effect of roof geometry...
