Buried Fiberglass Pipe Performance and Installation Requirements and Design Calculations in International Standardization
This paper elaborates on a proposed standard covering details of fiberglass pipe buried installation requirements and criteria for selection of pipe stiffness. It also discusses the selection...

Inspection/Condition Analyses of Large Underground Pipelines
Inspection/Condition Analyses of Underground Pipelines (sewers and conduits) will be a necessary function of the pipeline Owner/Operator. The Condition Analyses and Inspection phases are...

Large Diameter Plastic Pipe Design
This paper presents a rationale for the design of large diameter plastic pipes for gravity flow applications. This procedure, applicable for all plastic pipes, adapts state-of-the-art...

Design of Non-Pressure Very Flexible Plastic Pipe
There is considerable debate about the correct structural design procedure to be used for very flexible plastic pipe (VFP) - typically glass-fiber reinforced pipe (GRP), reinforced plastic...

Advances in Selective Withdrawal
The authors present the results of recent selective withdrawal research in the form of a general mathematical description of this stratified flow phenomenon. A new description for boundary...

Yakima Remote Control System: Supervisory Control and Data Acquisition
The Yakima Remote Control System is a computerized supervisory control and data acquisition (SCADA) system developed for the operation of the Bureau of Reclamation's Yakima Project in...

Response of Floating Structures in a Directional Sea
A finite element numerical model is presented to predict the behavior of long floating structures in a multi-directional sea. A follow up numerical model analyzes an important but mostly...

Vortices at Vertical Intakes
This paper presents the results of an experimental investigation designed to predict the formation of weak, free-surface vortices at vertical intakes with a headrace channel. A weak vortex...

Overtopping of Small Dams?An Alternative for Dam Safety
A research effort was initiated in 1983 by the Bureau of Reclamation to gain insight in the development of cost-effective modifications to small embankment dams which would enable them...

Embankment Overtopping
Embankment overtopping and dam safety are major concerns of civil engineering and the general public. Very little is known about overtopping events and much less has been published or...

Analytic Solution for Seepage from Saturated Soil Behind a Braced Wall
The locations of streamlines and equipotentials for two-dimensional flow in the vertical plane normal to a vertical retaining wall can be determined by various methods. Recent extension...

Cazenovia Creek Model Data Acquisition System
The purpose of the model is to reproduce river ice breakup phenomena for optimizing the design of an ice control structure. The performance of the ice control structure during a simulated...

Transport by Cable: Possibilities and Limits
Cable systems offer a high degree of passenger safety; they do not cause pollution and can, in a very flexible way, be adapted to the local conditions. They can be operated as reversible,...

Investigation of Design Criteria for APM Guideways
Designers have relied mostly on the provisions of the American Association of State Highway and Transportation Officials (AASHTO) Standard Specifications for Highway Bridges. Sometimes...

Design Criteria Impacts on Guideway Development
A highly definitive design criteria or performance specification is frequently developed for new transit systems. The criteria are intended to protect the owner's interest...

A Unique Communication System for Aerial Ropeways
The basic principles of operation of a Double Reversible Aerial Tramway are introduced. A brief note is given explaining a safety circuit or survey current used on the haul rope, since...

Planning and Environmental Assessment of New Transit System
The guideway of the new transit system 'KANAZAWA SEASIDE LINE' which Yokohama City has started construction is designed as an elevated type throughout the line,...

The Aerometro Suspended Rail System
The unique flexibility of the Aerometro Suspended Rail System offers an excellent opportunity for addressing urban transit needs. It is capable of prefabrication off-site, relatively simple...

Safety Aspects of Detroit DPM Station Designs
The Detroit Downtown People Mover (DDPM), currently under construction in the Central Business District of downtown Detroit, offered a unique set of challenges to the architects and engineers...

Alignment Special Structures for Vancouver's ALRT
This paper describes the special long-span structures, offset columns, and bent structures used in situations where the standardized guideway components used in over 90 percent of the...
