Next-Generation Local Scale Hydromet Forecasting System
Research and development work is being conducted for the National Weather Service on a new-generation flash flood monitoring and forecasting computer workstation. The workstation represents...
Hydrologic Aspects of Flood Warning?Preparedness Programs
A reliable flood-threat recognition system is a vital component of a sound flood warning-preparedness program. Fundamental questions associated with the development of a flood-threat recognition...
Dispersion of Tracers Along the Coast of Singapore
The primary objective of the present study is to model numerically the dispersion of a cloud of fine radioactive tracers along the east coast of Singapore. The results of a hydrodynamic...
An Acoustic Doppler Discharge-Measurement System
A discharge-measurement system that uses a vessel-mounted acoustic Doppler current profiler has been developed and tested by the U.S. Geological Survey. Discharge measurements using the...
Modeling Not By the Numbers
A model is likely to be the tool for making predictions of the ecological impact of an engineering decision. However, ecologists often find it difficult under pressures of time and lack...
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...
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...
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....
Reliability Assessment of Wood Components
Considerable progress has been made in the nondestructive evaluation (NDE) of wood components since the introduction of the first concepts more than twenty-five years ago. New stress wave...
Wood Variability Effects in Structural Assessment
Engineers evaluating the load carrying capacities of in-service wood structures commonly determine the strength and stiffness properties of structural wood members by various assessment...
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...
Long-Term Performance Reliability of Wood Materials
The United States faces a major task in maintaining and rebuilding the nation's infrastructure in the 1990's and beyond. Economic constraints have limited funds...
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...
U.S. Coast Guard Experience with Commercial FRP Vessels with Respect to Structural Reliability
The U.S. Coast Guard currently inspects over 1000 fiber reinforced plastic (FRP) vessels used in commercial passenger service. The designs include monohulls, catamarans, hydrofoils and...
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...
