Saltation in a sentence as a noun

One measurement where video might be valuable is measuring the saltation threshold, or the wind speed at which grains begin to move, of the surface using rotor downwash.

If avalanches can behave like a fluid due to a saltation layer, and saltation can happen to sand particles in wind, then couldn't the streaks be caused by sand/wind instead of water?Any geologists reading that could offer an opinion?
