What is the purpose of gated pipe in a surface irrigation system?

The primary purpose of gated pipe in a surface irrigation system is to convey water from the mainline to furrows effectively. Gated pipes have openings or gates that can be opened or closed to control the flow of water into specific areas or furrows. This allows for a more efficient distribution of water across a field, ensuring that crops receive the necessary moisture while minimizing waste and runoff.

By utilizing gated pipes, farmers can tailor the irrigation process to the specific needs of different sections of their fields based on factors like crop type and soil moisture levels. This system enhances water management and can improve crop yields while conserving water resources, making it a crucial component of surface irrigation techniques.

In contrast to this, creating a barrier for water flow would prevent the movement of water necessary for irrigation, filtering sediment does not pertain to the function of gated pipe, as that is generally managed within the water source or through separate filtration systems, and increasing pressure is not a role fulfilled by gated pipes but rather is achieved through pumps or system design modifications.
