Palaeohydraulic reconstruction of floods in upland UK bedrock streams: progress, problems and prospects
Palaeoflood evidence from five small upland Pennine catchments in the UK is used with the HEC-2 flow routine to simulate Holocene peak discharges. Even allowing for uncertainty, sensitivity...

Route 5: Steel Fibre Shotcreting in Shing Mun Tunnels Hong Kong?Specifying for Innovation
The Shing Mun tunnels form the central 2.6 km length of the Route 5 Highway connecting Tsuen Wan and Sha Tin New Towns, Hong Kong. The crossing of one of the areas was particularly difficult,...

Prediction of Embankment Dam Breaching for Hazard Assessment
Downstream hazard assessments for dams require prediction of 1) whether a breach could form, and 2) the hydraulic characteristics of the breach for use in calculations of discharge and...

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...

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...

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...

Selection of Optimum Route and Number of Stations for the Seoul-Pusan High Speed Rail System
The construction of the 411 km-long Seoul-Pusan high speed rail line began in June 30, 1992. The line connects Seoul and Pusan which are the first and the second largest cities in Korea....

Selection and Analysis of Florida's High-Speed/Intercity Rail Routes
Events during 1990 and 1991 in Florida's High-Speed Rail Franchise process have driven the project toward the status of a public works project. With greater public participation than originally...

Maglev Guideway Route Alignment Parameters
Passenger comfort at high maglev vehicle speeds (110 to 134 meters per second) has significant impact on the proposed use of the existing highway and railroad rights-of-way for hosting...

Safety Hazards of Maglev Guideway and Route Integrity
This paper presents an assessment of safety hazards associated with high-speed transportation on the ground. Hazard sources and consequences are identified through establishment of system...

Modeling Route Guidance Systems Using the Integration Model
In-vehicle Route Guidance Systems (RGS) have been proposed as a potentially cost-effective means of alleviating the impact of traffic congestion in urban areas. This paper describes means...

An Information Network for Route Guidance and Travel Guidance Systems
Automotive Route Guidance Systems are being marketed and tested around the world. These systems provide easy-to-follow, step-by-step instructions to guide a driver to any location in a...

Two-Dimensional Flood Hazard Simulation on Alluvial Fans
The incentive for flood hazard delineation on alluvial fans is development. Drainage plans and flood mitigation design require prediction of flow hydraulics for a range of hyperconcentrated...

Dam-Break Study for Large Floodplain Area - A Case Study
In simulating a dam break flood in a large floodplain, the maximum flood level is sensitive to the off-channel storage volume used in the channel routing. An incorrect estimate of the...
