ABSTRACT UNIFORMITY of water applied along the travel path and along the lateral was measured for a linear-move and a center-pivot sprinkler machine. High uniformity occurred near the guide towers, which had very constant movement, and low uniformity occurred near the middle towers, which had very irregular movement, for both machines. With one exception, however, correlation between variability of tower movement and variability of catch-can data was weak. We also found no correlation between nonuniformity along the lateral and variability in the nozzle discharges. Nonuniformity along the lateral appeared related to the movement of the towers..
