noun
simulated waterfall in a dry garden
A landscape feature in a Japanese dry garden (枯山水) that represents a waterfall using stones and gravel, without actual water. The spelling 枯滝 is especially associated with this sense.
この枯山水の庭園には、枯滝を表す石組みがある。
In this dry landscape garden, there is a stone arrangement representing a simulated waterfall.
枯山水 is the broader term for a dry landscape garden, while 枯滝 specifically refers to the simulated waterfall feature within such a garden.
Compound of 枯れ (kare, 'dried up') + 滝 (taki, 'waterfall'). The kanji 涸 specifically means 'dry up' (of water), while 枯 means 'wither' (of plants) but is also used for drying up. The spelling 枯滝 is conventional for the garden feature.
