Translation

ダム / 水をせき止める構造物 / 堰

Meaning

Dam is a barrier built to hold back water and control its flow, often creating a reservoir. The spelling trap is damn: dam is an engineering word, while damn is a curse or strong informal word.

Examples

• その川には新しいダムが建設されました。
  A new dam was built on the river.
• 大雨の後、ダムは大量の水を保持しました。
  After heavy rain, the dam held back a large amount of water.
