Wind-induced snow transport plays a key role in uneven snow drift on rooftops, yet the mechanisms driving this transport remain poorly understood. To investigate the mass transport of snow drifting on rooftops, this study systematically conducted a series of wind tunnel experiments using blowing snow on low-rise flat roofs. High-density silica particles were employed, and various test parameters, including snowfall, wind speed, roof span, and blowing duration, were varied. The results showed that the snow-depth shape on the central axis of a roof can be summarized and simplified into four typi...
