Construction of CCM Overtopping Protection on Three Parkway Dams
Cellular concrete mat (CCM) systems have been installed as overtopping protection on three small embankment dams along the Blue Ridge Parkway. Based on field tests by others and on the...

Economical Solution for Flood Overtopping Potential at Senator Wash Dam
A breach analysis of North Dike for overtopping with the crest modified to the lower elevation was required to ensure the breach discharge would be adequate to prevent overtopping of Senator...

Rehabilitation of Plane Nine Dam
Plane Nine Dam, an earthen water supply dam near Altoona, Pennsylvania, was constructed in 1907. The dam performed satisfactorily for more than 80 years but it deteriorated with time and...

Bureau of Reclamation Experience with Innovative Solutions to Increased Design Floods
Over the last several decades advances in the hydrologist's ability to estimate floods have resulted in increases to the design floods for many existing drainages. As with other dams throughout...

Use of Flood Control Features for Environmental Mitigation
The US Army Engineer District, Vicksburg (CELMK), plans to construct up to 167 water control structures, 52 confined disposal facilities, and 47 barrow pits as part of a major flood control...

Reliability Curves for Reservoir Performance
Seattle District, U.S. Army Corps of Engineers, has developed a family of reservoir guide curves that illustrate reliabilities when storage conditions gradually decline from 98% to as...

Wynoochee Lake and Dam?Flood Storage Reevaluation Study
With the desire to increase the revenue generating potential of the Wynoochee Lake and Dam Project the cities of Tacoma and Aberdeen, Washington, have pursued the potential for retro-fitting...

Real-Time Water-Control System for the Trinity River, Texas
To provide information for improved flood prevention and control in the Trinity river basin in Texas, we developed a real-time water-control system that (1) retrieves rainfall and streamflow...

Hydrologic Analysis of Leveed Interior Areas
Flood damage reduction projects that include levees or flood walls usually involve special problems associated with isolated interior areas. Storm runoff patterns may be altered and remedial...

A Derived Flood Frequency Distribution for Ungaged Catchments
Flood frequency distribution for ungaged catchments are described in the article. The various parameters that effect the flood frequency distribution are describes. Influence of the climate...

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...

Utilization of Roadway Crossings as BMP's in Urban Areas
Roadway crossings of natural waterways in the urban setting can be used as Best Management Practices (BMP's) by retrofitting existing outlet structures. Pollutant removal is contingent...

Floodplain Delineation Using TINS
Triangulated Irregular Networks (TINs) are becoming an increasingly common tool for modeling terrain surfaces on the computer. They are formed by the triangulation of scattered xyz data...

Multiple Objectives, Uncertainty and Routing Decisions for Hazardous Materials Shipments
Explicit consideration of multiple objectives and uncertainty is important in hazardous materials transportation, particularly in regulating routes or making routing decisions. Application...

Algorithms for Efficient Real-time Traffic Assignment
Fast algorithms are essential to accomplish real-time traffic assignment for optimal routing or traffic prediction under ATMS/ATIS. User-equilibrium and system-optimal traffic assignment...

A Spatial Decision Support System for Vehicle Routing
This paper describes the design, development, and implementation of a computer aided system for planning efficient network maintenance routes. The system has been used to design snow and...

An Application of Fuzzy Set Theory to Preference Analysis in Bus Route Choices
One of the difficulties in applying fuzzy set theory to the real situation is how to determine membership functions. In this study, a questionnaire survey was conducted to assess bus riders'...

High Speed Rail: An Alternative Route to Preserve Quality of Life in the Northwest
The impacts of population growth threaten quality of life in the Pacific Northwest. Existing transportation systems cannot meet projected demand nor special needs of an aging society....

Magnetic Levitation (Maglev) System Integration with Other Urban and Inter-City Transportation Modes
Hypothetical intracity maglev routes are applied to 11 United States metropolitan areas to enhance intermodal passenger transfers at existing bus terminals, metro stops, rail stations,...

High-Speed Surface Transportation Cost Estimating
The cost of building and operating high-speed surface transportation (HSST) systems in the United States is a critical factor in determining their feasibility. Costs are difficult to estimate...
