A khlong (also commonly spelled klong; Thai: คลอง (Pronunciation)) is the general name for a canal on the central plain of Thailand. These canals are spawned by the Chao Phraya, the Tha Chin, the Mae Klong Rivers, and their tributaries. The Thai word khlong is not limited to artificial canals. Many smaller rivers are referred to as “khlong”, followed by the name of the stream.
