Which nozzle option is associated with minimizing runoff on non-sodded banks?

• A. Stream
• B. Low angles
• C. Strip
• D. Short radius

Answer: (A)

On bare, non-vegetated banks the irrigation goal is to get water into the soil without flooding the surface and causing runoff. A stream nozzle fits this need because it delivers water as a narrow, directed stream rather than a broad spray. That concentrated flow wets a smaller area at a time and can be guided along the base of the bank, giving the soil a greater chance to infiltrate the water rather than letting it run off the surface. In contrast, patterns that spread water over a wide area or spray at higher angles tend to wet more surface area at once, increasing the likelihood of runoff on bare soil. So, the stream nozzle is associated with minimizing runoff on non-sodded banks by promoting controlled, infiltrative application.
