Quantitative analysis of snow deposition by use of models in a water flume

Snow loads on roofs of buildings and other structures are studied by use of models of buildings under water in a flume where fine sand is added to simulate blown snow. The pattern of drifting sand in water is remarkably similar to snow deposited by wind. Researchers at the University of Guelph in Guelph, Ontario, Canada, have established laboratory procedures to study quantitatively the deposition of white sand injected into flowing water in the flume. Data and photographs are included to illustrate the quantity of the sand deposited and to qualify the changes recommended for building codes for orientation of structures and highways as well as landscaping features through the knowledge obtained form this procedure.
