Khlong

A khlong (Thai: คลอง, pronounced [kʰlɔ̄ːŋ]) is a Thai word for a canal. Originally, the term referred to both natural streams and man-made waterways. However, in modern usage, the term primarily designates canals, often those forming part of an irrigation or transportation network.

Khlongs are particularly prominent in the central plains of Thailand, a region traversed by numerous rivers and streams. The extensive network of khlongs in this area has historically played a crucial role in agriculture, transportation, and flood control. These waterways facilitate rice cultivation and other forms of agriculture by providing irrigation and drainage. Historically, they were a primary mode of transport, allowing people and goods to move efficiently across the region.

Bangkok, in particular, was once known as the "Venice of the East" due to its intricate system of khlongs, which served as the city's primary transportation arteries. Although many of these khlongs have since been filled in and replaced with roads, a significant number still exist and continue to be used for transport, commerce, and tourism. Floating markets, where vendors sell goods from boats on khlongs, are a popular tourist attraction.
