Abstract

The feasibility of characterizing the structural properties of snow from its acoustic behavior is demonstrated. Snow has characteristics similar to many other acoustically porous media. An in situ experimental procedure, which meets the requirement not to disturb the deposited snow sample on the ground during the experiments is devised by means of acoustic sounding. Acoustic pulses incident perpendicularly on the snow surface and their return echos can be analyzed by the cepstral technique. A two-phase mechanical model, similar to that developed by Zarek for acoustically porous media, may also be formulated for snow.
