Seismic Design of RC Structural Walls with Unsymmetrical Cross-Sections
An overview of seismic design issues and current experimental research for walls with unsymmetrical cross-sections is presented. The experimental studies include approximately 1/4 and...

Review of Cold-Formed Steel Purlin Design
The use of cold-formed steel members as roof purlins for single story industrial and commercial buildings is commonly recognized. These members typically have either a C- or Z-shaped cross...

Optimization of Controlled Structures: Using H Theory
This paper presents the algorithm for the design of a controlled structure in which the structural and control systems are designed simultaneously. The problem is posed as an optimization...

Involving the Public to Reach Consensus in Water Resources Projects - An Interdisciplinary Perspective
The San Diego County Water Authority (Authority) is developing the Emergency Storage Project (ESP) to improve the reliability of the county's water supply in the event of an extreme emergency,...

Wetland Loss Rates and Agricultural Drainage
The current paper uses National Resources Inventory data to document the relation between private on-farm agricultural drainage investment activity and wetlands loss. The paper presents...

Integrated Geology and Preliminary Cross Section Along the North Ramp of the Exploratory Studies Facility, Yucca Mountain

Effect of Pier Geometry on Scour in Graded Gravels
This paper summarizes the results of laboratory tests performed on clear water scour around circular and rectangular cross section bridge piers, embedded in a non-uniform coarse sediment...

Design of Manning's-Rougness-Coefficient Study in New York State
Field-collected hydraulic data can be used to compute roughness coefficients for channels with different hydraulic characteristics. Suggested criteria for the design of a roughness-coefficient...

Floodflow Effects on Riparian Vegetation in Arizona
A relation for estimating changes in the condition of riparian vegetation as a function of stream power was developed for stream channels in central Arizona. Flood and vegetation data...

On Habitat Simulation in Mountain Rivers
Mountain rivers are quite different from other rivers and one of the characteristics that distinguish them from others is the large variation in velocities with time, with location in...

Characterization of Incised Channel Development
A combination of hydraulic and geotechnical techniques have been applied to predict future cross-section morphology in incised channels. The SAM program (Copeland, 1991) computes combinations...

Temporal and Spatial Variations of Suspended Sediment Concentration during Navigation Traffic in a Natural River
Suspended sediment samples were collected within the channel border area during barge-tow passage events at three cross-sectional locations on the Upper Mississippi River. Typical plots...

Assessment and Recommendations for the Enhancement of the Bardawil Lagoon Outlets

Hurricanes of 1992
Lessons Learned and Implications for the Future
In 1992, Hurricanes Andrew and Iniki devastated portions of Florida, Louisiana, and Hawaii causing over $35 billion in damages and the loss of 38 lives. Hurricane Andrew, which accounted...

Travel Demand with Forecasting Microsimulation
Transportation planners forecast travel demand using techniques that are based on dissagregate models estimated from cross-sectional data. Their forecasts are usually single future time...

The Use of Built-Up Compression Members—A Fabricator's Viewpoint
A variety of cross-sections of built-up compression members that have been used are shown. Suggested items that need to be addressed for the successful design and fabrication are discussed....

Single-Shell Shotcrete Method
On a 60-m-long test stretch in the course of the construction of the Munich Subway the single-shell jointless shotcrete method was employed. In this case the standard cross section of...

Effect of Lead Shielding on Small Cask Criticality
A study was performed to evaluate gamma shield effects on criticality safety for two modern legal weight truck casks. The lead gamma shield of a small spent fuel shipping cask increases...

Geometric Analyses of Alternative Models of Faulting at Yucca Mountain, Nevada
Realistic cross section tectonic models must be retrodeformable to geologically reasonable pre-deformation states. Furthermore, it must be shown that geologic structures depicted on cross...

Alternative Designs for Permanent Protection of the San Luis Rey River Aqueduct Crossings
The San Diego County water Authority was organized to provide an imported supply of water to the San Diego region. The sole source of the water to the Authority is Metropolitan Water District...
