Sewage Effluent Turned to Snow: Provides Storage, Removes Pollutant
Sewage effluent can be stored in an artificial snowpack as evidenced by research performed in 1974 by the Upper Yampa Water Conservancy District of Colorado. The three month long experiment...

Hydrology of Patch Cuts in Lodgepole Pine
Paired plot studies of soil water and snow water equivalents were conducted from 1968-1973 in the lodgepole pine type on the eastern slope of the Colorado Front Range at an elevation of...

Stability of Half-Barrel Orthotropic Shells
The overall buckling of half-barrel shells made of corrugated steel sheets is studied in this paper. This type of buckling is recognized as a prime factor in defining ultimate load carrying...

Effect of Snow Cover on Upward Movement of Soil Moisture
The soil moisture in the ground beneath a snow cover in the north central United States has been observed to increase during the winter season. The maximum prethaw soil moisture frequently...

Membrane Solutions for Shells with Edge Constraint
Several problems in the analysis of shells of revolution are examined for which only the membrane solutions are needed. The significant displacement of truncated shells and domes under...

Post-Buckled Strength of Large Space-Truss
To be able to meet the extraordinary design specification that the roof of an airplane hangar, severely damaged by an explosion must not collapse for the load case of dead weight plus...

Ecological Consequences of Winter Cloud Seeding
Some ecological consequences of cloud seeding are considered with special reference to winter orographic programs using silver iodide as the seeding agent. It appears that with present...

Colorado Pilot Project: Design Hydrometeorology
A large, 4-yr winter cloud seeding pilot project has been started by the Bureau of Reclamation in the San Juan Mountains of Colorado. This paper describes how precipitation, snowpack,...

Demand Activated Transportation for the Elderly
A free transportation service has been established for elderly residents in the Model Neighborhood Area of Buffalo, NY. Transportation is provided on a demand activated basis, in which...

Snow Fence Shielding of Precipitation Gages
Wind has long been recognized as a major source of error in the measured catch by precipitation gages. The generally accepted Alter or Nipher shields improve the characteristics of the...

Routing for Public Service Vehicles
City services requiring the routing of vehicles which must cover every street in a complex highway network are investigated. An overview of the problems arising in planning such services...

Suppression of Evaporation Losses from Snowpacks

Sediment Yields from Central Colorado Snow Zone
To determine the effects of roads and forest-cover changes on sediment yields, measurements were made on one carefully logged and two undisturbed watersheds in the Fraser Experimental...

Operational Experience with Snow Pillows in California
A pressure pillow system is described for use in measuring snow water equivalent in a snowpack. These pillows used in conjunction with coding devices and radio systems can transmit the...

Probability of Plastic Collapse Failure
The probability of a plastic collapse failure for a structure of random material strength acted on by random loads can be evaluated considering that failure may occur by any one of the...

Viscoelastic Properties of Snow and Sand
The frequency dependence of dynamic properties of the viscoelastic solids is studied based on the theory of linear viscoelasticity. The variation of dynamic moduli, viscosity, and the...

Long-Chain Alcohol Suppression of Snow Evaporation
Autoradiographs and pan studies in the laboratory indicate that long-chain alcohols suppress evaporation from snow if applied as an emulsion. A 1 mg point source of activated hexadecanol...

Development of Rain Gages
The development of rain gages is considered in detail for the period of about 400 B.C. to the end of the 16th century and, more briefly, for the period beginning with the 17th century...

Weather Modification in the Southern Sierras
This article presents an historical account of 15 yr of continuous winter-time cloud seeding to enhance snowpack in the upper San Joaquin watershed of the southern Sierra Nevada. The project...

Snowshed Location And Design
The location and design of snowsheds for avalanche defense must be based on careful studies of terrain, the frequency of avalanche occurrence, and the size of the avalanche. Preliminary...
