Abstract
A rotating disk with four open, adjustable slots was mounted on a portable single‐nozzle sprinkling infiltrometer. When spun at about 60 rpm, essentially uninterrupted artificial precipitation reached the ground surface. At intensities ranging from 1 mm/hr to more than 150 mm/hr, uniformity coefficients were little different from those achieved by the nozzle itself.
