New Admixtures for Cold Weather Concreting
Chemicals were tested for their ability to promote strength gain in portland cement concrete at low temperature. The admixtures depressed the freezing point of the mix water and accelerated...
High-Performance Concrete in All-Weather Deck Pours
A high-performance concrete mix enhanced with a combination of microsilica, superplasticizer, and high dosages of an corrosion-inhibiting, accelerating admixture (calcium nitrite); proved...
Impact of Cold Weather on Building Construction Scheduling
Weather impact on a building construction schedule is often significant in cold regions. Most deterministic scheduling methods are unable to directly account for the effects of weather...
Cold Climate Building Research at Wasa Base, Antarctica
During the Antarctic summer season of 1988-89 a permanent Swedish research station was erected at Dronning Maud Land, Antarctica. The station, named Wasa, is situated on a nunatak. A corresponding...
Spray and Ice Measurement Instrumentation for Ships
Bow slamming is the primary water delivery mechanism for ship superstructure icing. Spray flux is largely dependent upon hull dynamics, and cannot be computed numerically with current...
Recommended Cold Regions Meteorological Instrumentation
For nearly 30 years, CRREL has studied environmental conditions in winter weather. These efforts have concentrated on providing field-measured meteorological data and historical climatological...
The Pittsburgh MAGLEV Project
A passenger transportation crisis exists in the United States which experts predict will only worsen, wasting billions of U.S. dollars. Magnetic Levitation (MAGLEV) is a promising new...
Cold Regions Engineering
This proceedings consists of papers presented at the Cold Regions Engineering Specialty Conference held in West Lebanon, New Hampshire from February 26-28, 1991. The papers cover nine...
The Growing Meet Market
The Delaware cities of Dover and Wilmington are only 5 mi apart. Their combined populations barely exceed 100,000. Yet each city is planning to build a new convention center to corner...
A Regional Mapping Procedure for Finite Element Mesh Design
The paper summarizes our recent work in the development of practical algorithms for the automated mesh design in finite element stress analysis. A regional mixed mesh improvement procedure...
Building a Geographic Information System (GIS) for Siting New York City Sludge Management Facilities
Siting studies for waste facilities usually focus on a particular geographic region, or a defined study area, and are restricted to a specific technology. However, the siting of land-based...
Establishing a Geographic Information System
The ultimate test of an advancement in civil engineering is the successful integration of aspects of the advance into the general engineering community. Success stories in this area include...
Regional Flood Control District GIS Applications
Clark County, Nevada is currently implementing a Geographic Information System (GIS) to support County planning and engineering functions. The Regional Flood Control District is in the...
Creativity and Water Resources: Theory and Stimulation
An attempt was made to assess the evolution of the water resources field. First, the most significant scientific advancements in the field since 2000 BC until early 1900 AD were listed...
Urban Storm Drainage Design Hydraulic Principles
Chapter 6 of the manual on Design and Construction of Urban Storm Water Management Systems discusses the hydraulic principles and equations under which drainage system structures must...
Urban Water Issues/Strategies in the Humid Tropics
Annual rainfall volumes in the Humid Tropics are large, and the events can be quite intense, but they can also be highly variable, with periods in which little or no rainfall occurs. Streams...
Conceptual Model for Performance-Based Management of Regional Water Systems
The national shift in emphasis from top-down development plan orientation in water resources, wherein the federal government assumed the dominant role, to the shared partnership approach...
Regional Water Supply Development in the SWFWMD
Regional water supply authorities have been formed within the Southwest Florida Water Management District in an effort to meet growing water demands of a rapidly expanding population....
Regional Water Supply Management in Southern New Hampshire
This paper presents the findings and recommendations of the Southern New Hamsphire Water Supply Study regarding regional water supply management in the study area. The study area includes...
Regional Water-Supply Development and CWA Section 404
Regional water-supply development is generally promoted because of potential cost savings and improved system management, but regionalization may also provide an opportunity to reduce...
