A Diffusion Hydrodynamic Model of a Shallow Estuary: Verification
Many of the hydrodynamic models used for estuary tidal flows and storm surges are based on two two-dimensional hydrodynamic equations which are obtained form the full three-dimensional...
The Courant Number and Unsteady Flow Computation
The Courant number C, the key to unsteady flow computation, is a ratio of physical wave velocity, ?, to computational signal-transmission velocity, ?, i.e., C = ?/?. In this way, it uniquely...
River Engineering Flows and Some Related Structures (State of the Art)
The first part of the paper deals with a simplified overall review of water flows. Laminar versus turbulent, visualization of flow with unsteady 3-D manner and some typical hydraulic structures...
A Culvert Analysis Program for Indirect Measurement of Discharge
A program based on the U.S. Geological Survey (USGS) methods for indirectly computing peak discharges through culverts allows users to employ input data formats used by the water surface...
Analysis of Local Scour at Bridge Piers
Many studies have been performed on the cause and effects of local scour at bridge piers, and various prediction equations have been generated based on these studies. The general approach...
Simulation of 3D Free Surface Flows in Hydraulic Structure with Submerged Flow Passages
This paper presents primarily the results of an application of the newly refined computational simulation model to study three-dimensional flows in a lock and dam system, which has submerged...
Flow Study of In-Service Sanitary Sewers Rehabilitated with Insitupipe
In an effort to define the flow characteristics of sanitary sewer segments rehabilitated with Insituform under normal in-service conditions, Insituform of North America, Inc. (currently...
Pipeline Leak Detection Based on Mass Balance
Current technologies in Supervisory Control and Data Acquisition (SCADA) systems enable pipeline leak detection to be carried out in real time by software-based methods. This paper discusses...
Relocating a 54-Inch Diameter Force Main without Interrupting Wastewater Flow
The City of Tampa, Florida, was faced with the challenge of relocating three segments of an old 1372 mm (54-in.) diameter reinforced concrete pipe force main, totaling nearly a mile in...
Developing an Air Transportation Hub?A Planning and Analysis Process and its Application in Taiwan, R.O.C.
The Ministry of Transportation and Communications of the Republic of China in Taiwan wanted to know whether it was feasible and desirable to develop an air transport hub at Chiang Kai-shek...
Identifying Transportation Control Measures: a Straighforward Approach to Identifying Transportation Control Measures to Address Concerns with Air Quality
The 1990 Clean Air Act Amendments (CAAA) exemplify society's increasing environmental concern. Regions not attaining the CAAA requirements must develop methods to reduce the pollution....
Commercial Aviation Maintenance
The Federal Aviation Administration (FAA) issues regulations and advisories for commercial airlines which establish the basis of the aviation maintenance and inspection programs. Commercial...
High Speed Rail Initiatives in Korea
The purpose of constructing a high speed rail on the Seoul-Pusan corridor is many fold: to solve intercity traffic congestions, to save energy, to reduce air pollution, and to make possible...
Pierce Transit's Experience with an Alternate Fuel Compressed Natural Gas January-December 1992
At the end of 1992, Pierce Transit's CNG fleet consisted of 30, 40-foot Orion buses, 19 ElDorado Buses, on GMC 'New Look' bus, one 1990 Chevy Celebrity, and one Collins Shuttle van. As...
The TrAAm People Mover Project
TrAAm is the new exclusive people mover for American Airlines at the Dallas/Fort Worth International Airport. Since opening in late 1991 it has been carrying over 18,000 people a day....
American Airlines' TrAAm System Vehicle Modification/Conversion Program
In October of 1992 American Airlines inaugurated a new people mover service among four stations within its two-terminal complex at the Dallas/Fort Worth Airport (D/FW). Named the `TrAAm,'...
