What is the term for the channel that directs water from a source to an irrigated area?

The term that specifically describes the channel directing water from a source to an irrigated area is commonly referred to as a main canal. This type of canal serves as the primary conduit for transporting water from larger water sources, such as rivers or reservoirs, to the designated irrigation zones. Main canals are crucial in irrigation systems, as they ensure that a significant volume of water is efficiently distributed over large agricultural areas.

While lateral canals are also part of irrigation systems, they branch off from the main canal and carry water to smaller, specific areas within the irrigated zone. The term "irrigated canal" is less commonly used and may not specifically refer to a recognized channel in conventional irrigation terminology. Therefore, the main canal accurately conveys the primary channel's role in the context of irrigation systems.
