SUBTERRANEAN RIVER

A 'subterranean river' is a river that runs beneath the ground surface. These rivers can either be entirely natural, or a result of the deliberate installation of a culvert to channel a flow from the surface to underground, usually as a part of urban development.
To reverse this process is known as daylighting a stream and is a visible form of river restoration. One successful example is the Cheonggye Stream in the centre of Seoul.^[1]
Examples of subterranean rivers include:

★ London's River Fleet

★ Zenne flowing underground through Brussels

★ the Dommel underneath 's-Hertogenbosch in the Netherlands

★ The Mojave River in southern California

★ Santa Fe River in northern Florida.

★ Palawan in Puerto Princesa Subterranean River National Park on the island of Palawan, Philippines

★ Son Trach river in Vietnam

★ the Sac Actun system (named after the Mayan name of the larger of the two branches) is the result of a confirmed connection between two other rivers previously thought to be separate. Discovered by divers Robbie Schmittner and Steve Boagarts in January 2007, the full length is 153.6 kilometers long and a maximum depth of 72 meters underneath the Yucatán Peninsula.^[2]
Another notable example is the subterranean portion of the Nile River.
A flow somewhat similar to a subterranean river is a large body of moving water that exists in the Atlantic Ocean near the floor, part of the North Atlantic Current.
