An artificial water channel is a man-made structure designed to control the flow of water. It typically consists of a CANAL, a SLUICE, a TANK, a RACE, and a STRAIT. A CANAL is an artificial waterway used for transportation, irrigation, or drainage. A SLUICE is a gate or valve that controls the flow of water. A TANK is a large container for storing liquids. A RACE is a channel for directing the flow of water. A STRAIT is a narrow passage of water connecting two larger bodies of water.
