1.
below-floor flooding; flooding under the floor
A classification used in Japanese disaster reporting for flooding in which water enters the space beneath a house's floor but does not rise above the floor level into the living space. This is the less severe of the two standard damage categories, the other being 床上浸水.
床下浸水の被害が出た。
There was below-floor flooding damage.
台風で市内の数十軒が床下浸水した。
Due to the typhoon, dozens of houses in the city experienced below-floor flooding.
大雨の影響で床下浸水が五十軒、床上浸水が十軒報告されている。
As a result of the heavy rain, fifty houses have been reported with below-floor flooding and ten with above-floor flooding.
Composed of 床下 ("under the floor") + 浸水 ("flooding, inundation"). A standard category used by Japanese municipalities, fire departments, and news media when tallying damage from heavy rain or typhoons. Because traditional Japanese homes are built on raised foundations with a crawl space beneath the floor, water can enter that crawl space without reaching the living area; such cases are classified as 床下浸水.
USAGE:
- Always appears as a fixed compound; it is not productive as a general verb phrase.
- Typically used as a suru-verb or a simple noun: 床下浸水する, 床下浸水の被害.
- Contrasted with 床上浸水, which is treated as more serious because water enters the living space and damages tatami, flooring, and furniture.
COMMON COLLOCATIONS:
- 床下浸水の被害: damage from below-floor flooding
- 床下浸水する: to be flooded below floor level
- 床下浸水が発生する: below-floor flooding occurs
- 床下浸水○○軒: XX houses with below-floor flooding
CONTRAST WITH:
- 床上浸水: above-floor flooding — water enters the living space; considered more severe and often triggers disaster assistance
RELATED TERMS:
- 浸水: flooding, inundation (the general term)
