Wind Tunnel Modeling of Time-Dependent Drift Topography
The aeolian wind tunnel is a useful tool for investigating not only the saltation physics of wind-driven sand, soil or snow, but also for determining the time-dependent development of...

Drifted Snow on Roofs
Drift snow loads on multilevel roofs account for about 75 percent of all snow load related roof collapses. A case history of snow drifts provides the foundation for a discussion of the...

Snow Fence Operational and Material Testing
The proliferation of snow fence products since the late 1970's presents an opportunity for optimizing the control of drifting snow. It also presents a challenge in discriminating...

Research Study of Highway Snowdrifting in Canada
Millions of dollars are spent annually to maintain Canadian highways in order to make them safe for motorists during the winter. In Ontario, it is estimated that on average $3,000/km of...

Snow Transport as a Function of Wind Speed and Height
When limitations are placed on mass flux in the saltation layer, a regression equation relating mass flux to wind speed and height above surface, developed by Mellor and Fellers (1986),...

Ecological and Geomorphic Impact of the Destruction of a Coastal Sand Dune System in a Sand Spit
Two main effects of the destruction of the coastal dunes at the sand spit of Estero de Punta Banda, (B.C., Mexico) were studied comparing unaltered and altered adjacent zones, The amount...

Use of Lysimeters to Measure Fog Interception in Tussock Grassland New Zealand
Previous studies of the water balance of single Tussock plants in small non-weighing lysimeters over a range of elevations in east-central Otago province suggest that tussock grassland...

Statistical Analysis of Australian Ground Snow Loads
This paper is concerned with the statistical analysis of snow data from the alpine areas of southeastern Australia (above 1200 m). In these areas, the local variation is large and contour...

Applying a Simple GIS to PMP Analysis in a Microcomputer Environment
The analysis of probable maximum floods (PMF) in the Northwestern United States requires the inclusion of a snowmelt component combined with probable maximum precipitation. Traditionally...

Chaotic Characteristics of Snowmelt Runoff: A Preliminary Study
Chaos, the study of nonlinear dynamic systems, offers a way of observing order in systems previously thought to be random. In this study, we analyze snowmelt runoff from a small watershed...

Possible Climate Change and Its Impact on Snowmelt and Water Supply in California
Global climate modelers are forecasting relatively large future climate change, with warming of 2 to 5°C. These changes, if they do occur, would have major impacts on California's...

Snow Fencing to Increase Streamflow on Rangelands
Snow deposition and water yield were increased 55% and 127% respectively, and duration of surface runoff was lengthened 17 days in response to snow fencing a sagebrush-covered watershed...

Effects of Forest Cover on a Snowpack in the Sierra Nevada
Adjacent snowpacks in a clearing and under a forest canopy were compared over a decade at a site near Lake Tahoe. This comparison provides a few indications of the differences in snowpack...

Operational Remote Sensing of Snow Cover in the U.S. and Canada
The Office of Hydrology of the National Weather Service maintains a cooperative National Operational Hydrologic Remote Sensing Center, based in Minneapolis, to generate remotely sensed...

Soluble Pollutant Enrichment in Snow Covers
A mathematical model is presented to simulate enrichment of soluble pollutants in snow covers. The model is based on the liquid water flow, heat transport, and pollutant transport equations....
