What factors can contribute to irrigation system runoff?

Excessive watering and poor drainage are significant factors that can lead to irrigation system runoff. When a system applies more water than the soil can absorb due to saturation or because the drainage system is not functioning effectively, the excess water will flow over the surface instead of soaking into the ground. This can result in runoff, where water moves away from the intended area, potentially causing erosion and water waste.

Improper drainage exacerbates the issue; if the soil or system does not facilitate proper water movement, it will increase the likelihood of standing water and runoff. Therefore, managing the amount of water applied and ensuring that effective drainage is in place are crucial to minimizing runoff and promoting efficient irrigation practices.
