Time restrictions given for irrigation system operation are referred to as

The term "water window" specifically refers to the designated time periods when irrigation systems are allowed to operate. These restrictions are often set to manage water resources effectively, comply with local regulations, and minimize the impact on the environment. For example, certain areas might have restrictions in place to prevent irrigation during peak evaporation times or when water supply is limited.

By adhering to these time restrictions, irrigation technicians ensure that they are using water efficiently and responsibly, thereby contributing to sustainable practices in landscape and agriculture. This concept is crucial in maintaining a balance between plant requirements and available water resources.

Other concepts like irrigation frequency, water scheduling, and flow limits relate to different aspects of irrigation management. Irrigation frequency pertains to how often irrigation occurs, water scheduling involves planning when to irrigate based on various factors, and flow limits refer to the maximum amount of water that can be delivered at any given time. While they are all important in the management of irrigation systems, they do not specifically describe the time constraints placed on irrigation operations.
