The Stacked Drift Tunnel
The Mount Baker Ridge Tunnel is the first of its kind and the last: a forward thrust of technology and a look back to the flow of federal highway funds, which paid 90% of its cost. The...

Closing The Floodgates
The White Rock Creek basin in Dallas and Collin Counties, is one of Texas' most crucial resources. While large tracts of undeveloped land in Collin County remain under agricultural or...

Top Projects 1990
A dam, a bridge, an expressway, an interchange, flood control improvements, wastewater treatment and a dredged material containment embankment round out the 1990 Outstanding Civil Engineering...

Advances in Pipeline Materials
Pipelines transport water, storm run-off, process wastes, petroleum, natural gas, slurries, solids, sewage, steam and other fluids either by gravity or under pressure. Pipelines are also...

Franchising for the Future
Franchising is no longer reserved for hamburger stands or quick print photo processors. Now engineers may decide to join lawyers and dentists in future franchise operations. In today's...

Lower Granite Fish Guidance Efficiency System Model Study?Snake River, Washington
With the annual migration of adult salmon up the Columbia and Snake Rivers and the migration of their offspring (juvenile salmon) downstream to the ocean, new problems have developed with...

Study on Pneumatic Wave Power Conversion System with the Water Valve Rectifier
We experimentally and theoretically studied the energy conversion characteristics on a new type of wave power conversion system with water valves. The hydraulic model experiment was performed...

Theoretical Study on Capture Chamber with Lateral Entrance
A capture chamber with lateral entrance can be used in a pneumatic wave energy conversion system. In this paper, the output power coefficients of the capture chamber have been calculated...

Review of Garolim Tidal Power Project
The feasibility study of Garolim tidal power project made in 1981 was reviewed in 1986 and updated in 1988. The review study generally confirmed the result of the 1981 study. The generator...

Power Conditioning Options for Variable-Speed Ocean Energy Conversion Systems
As part of a recent wave energy feasibility study for the coast of North Carolina (SEASUN Power Systems, 1988), a survey was conducted of power conditioning and transmission technology....

SHRP Program: Asphalt Durability and Specification
The goals of the Strategic Highway Research Program (SHRP) program are an improved specification for asphalt binders and accelerated performance tests that can be employed by user agencies...

Field Installation of Strain Gaged Geotextiles
High-strength polyester geotextiles were used in two major Corps of Engineers projects: Wilmington Harbor, Del. and New Bedford, Mass. To verify design assumptions and as part of monitoring...

Waste Geotechnics and Geosynthetics
The geotechnology related to waste management focuses around assessing the movement of water and pollutant transport, containment of the pollutant so that it is unable to pollute the underground...

Construction Quality Assurance for Geomembranes
The results of and lessons learned from construction quality assurance (CQA) programs on 19 geomembrane liners are presented. The specifications are generally exceeded by comfortable margins...

Fiber Reinforced Plastic Grids for the Structural Reinforcement of Concrete
The use of fibre resin plastic grid is investigated as a primary bending reinforcement in concrete members. Laboratory bending data is compared with theoretical results using ACI 318-83...

A Prestressed Kevlar/FRP Structural System
The strength/stiffness characteristics of a new lightweight composite structural system have been investigated in this study. The proposed system is constructed of FRP(E-glass/isophthalic...

Concrete Pavement?Specification by Modeling
Concrete pavement specifications have traditionally been prescriptive with construction in-put defined. This practice does not include a definition of the product intended, restricts innovation,...

Displacement Measurement by Laser Interferometry and Image Analysis
Laser holographic interferometry was used for the evaluation of displacement fields on concrete and fiber reinforced concrete specimens. Transmission holography was used to analyze mortar...

Irrigation and Drainage
This proceedings consists of 70 papers presented at the National Conference on Irrigation and Drainage sponsored by the Irrigation and Drainage Division of the American Society of Civil...

Watershed Planning and Analysis in Action
This proceedings consists of papers presented at the 1990 Watershed Management Symposium held in Durango, Colorado from July 9-14, 1990. These papers present both research performed in...
