What role do flags serve during an irrigation audit?

• A. They mark locations of emission devices
• B. They indicate plant health
• C. They help measure soil moisture
• D. They show areas of water shortage

Answer: (A)

Flags play an important role in the irrigation audit process primarily by marking the locations of emission devices, such as sprinkler heads and drip emitters. This allows the auditor to easily identify and assess each device's performance, ensuring that the irrigation system is functioning as designed. By having a clear visual guide, the auditor can evaluate water distribution patterns, identify any deficiencies or misalignments in the system, and make informed recommendations for adjustments. This precise marking is crucial for effective auditing and ensuring efficient water use in landscaping. In contrast, while plant health, soil moisture measurement, and water shortage indications are important aspects of landscape management, they are not the primary functions of flags in this context.
