Unicode Version 17.0
堰
U+5830 "堰" CJK Unified Ideograph-# is a Chinese character that primarily means "weir" or "dam," referring to a low wall or barrier built across a river or stream to control water flow, raise water levels, or divert water for irrigation. In East Asian contexts, it is commonly used in words like "堰塞湖" (landslide dammed lake) and appears in place names and technical terms related to hydraulic engineering and flood management. Its structure combines the radical for "earth" or "ground" (土) with the phonetic component "匽," reflecting its connection to earthen barriers. This character is classified under the Kangxi radical 32 (土) and is used in modern Chinese, Japanese, and Korean scripts.
