The timing of flow stoppage is crucial for understanding water distribution in border irrigation because it directly influences how water is absorbed into the soil and affects the uniformity of irrigation. In border irrigation, water is allowed to flow through a designated border area, and when the flow is stopped, it allows for adequate penetration and distribution of water within the soil profile. Proper timing ensures that the water has enough time to infiltrate and reach the root zone of crops effectively.

If the flow is stopped too early, the water may not sufficiently penetrate the soil, leading to inadequate moisture for crops. Conversely, if flow is stopped too late, it can lead to excess runoff, waterlogging, and potential crop damage. Thus, managing the timing of flow stoppage is essential for achieving efficient and effective irrigation, making it a significant factor in understanding water distribution within this system.

While the other features, such as water depth measurement, soil texture analysis, and the type of irrigation pattern, are also important in the broader context of irrigation systems, the immediate control and management of water distribution in border irrigation primarily hinge on how well the flow stoppage is timed.
