Aerial photographs of a block of detached houses in the town of Takasu, Hokkaido, were used to create a 1:200 model for wind wind tunnel experiments on snowdrift formation with snow made of activated clay. The pattern of snowdrift formation was successfully reproduced, as verified by aerial photography and measurement survey. The effects of various conditions in and around the block on the formation of snowdrifts were also investigated, and it was found that windward snow piles affected the depth of snow within the town block. This result suggests the need to carefully determine the locations for piling removed snow at the block.
