On the Snow-Plough Effect when Cutting Water Saturated Sand with Inclined Straight Blades

Effects of Drifting on Snow Loads on Large Roofs
In areas that experience significant snow fall, snow loads typically produce the governing environmental load cases for a large span roof. Therefore for large span roofs there are considerable...

Design of Connections in Wood Structures: LRFD vs. ASD
This paper provides a comparison of connection design capacities using load and resistance factor design (LRFD) procedures and allowable stress design (ASD) procedures....

Steel Bar Joist Performance: Design Deficiencies and Defects
Several failures of steel bar joist roofs have been investigated by the authors in the past decade. Many of these failures or performance problems have corresponded to bar joists manufactured...

New Wells Safeguard Scenic Tahoe
Surface water for drinking and for snow-making is becoming scarce in the Lake Tahoe region, along the California and Nevada border. New Environmental Protection regulations regarding surface...

Colorado Dome
Innovative engineering and precise design helped engineers overcome a building's unique shape and difficult site to deliver the $71.5 million Jefferson County Government Center...

A Revised Snowstorm Maximization Method for Canadian Boreal Regions
A proposed refinement in the development of design snowpacks for use in the derivation of probable maximum floods (PMF) estimates in the Canadian Boreal is presented. Shortcomings in the...

Snow Estimation—A GIS Application for Water Resources Forecasting
In the Western United States approximately 75 percent of the annual runoff results from snowmelt. Observations of the snow cover provide an important source of information for forecasting...

Acidity and Chemistry of Arizona's Snowpacks
Acid snow, the frozen version of the acid rain phenomena, has been sampled in several western states, e.g., California, Nevada, Montana, and Oregon. Measurements of snowpack acidity in...

Getting Ahead of Snow and Ice
Winter maintenance is not the same anymore. New weather forecasting technologies are permitting snow and ice fighters to better predict when unsafe winter weather conditions will occur....

Snow and Ice Control in Japan and United States
Both Japan and the United States experience severe winter conditions that require major resources and large expenditures for maintaining highways. The maritime climate that prevails in...

Decision Support System for Multiobjective Service Route Design

Traffic Impact Assessment for Snow Disposal Facilities—Extended Abstract
Snow disposal facilities perform an integral role in the maintenance programs of many municipalities in canada and other northern countries. The most popular type of snow disposal facility...

Cloud Seeding: The Engineering is Done, but What About Social Impacts?
As engineers, we tend to focus on the technical aspects of cloud seeding, and may neglect important social aspects or potential side effects. Often people in the target area are more concerned...

A Removable Submarine Cover for Drydock No. 2 Modernization
In order to provide balanced overhaul capability and flexibility in the 1990's and beyond, the Portsmouth Naval Shipyard in Kittery Maine, a major U.S. Navy submarine and overhaul repair...

Processed-Snow Foundation Design at the Summit of the Greenland Ice Cap
The design and construction of a processed-snow foundation berm for an elevated building located at the summit of the Greenland Ice Cap is described. Weather conditions and design provisions...

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...

Future Technology for Disbonding Snow and Ice from Pavements
Current techniques to remove ice and compacted snow from pavement surfaces are costly because they needlessly crush or melt most of the ice layer. Also, in many cases they do not accomplish...

Multiphase Flows and the Modeling of Drifting Snow
Three categories of multiphase flow theories are commonly specialized for modeling drifting snow; the 'two-fluid' model, particle tracking schemes and kinetic...
