ABSTRACT DISTRIBUTION patterns of six typical lawn sprinkler types were determined during the summer of 1977. Tests were conducted on four sprinklers from each type under three pressure levels. Christiansen's Uniformity Coefficients (UCC) were calculated for the original pattern and for various overlaps of the sprinklers. Overlaps required to achieve minimum ac-ceptable UCC values were then determined. The output of each sprinkler was measured and application rates were calculated for individual pattern sizes at the three pressure levels. Two important factors for effective lawn watering include: (a) use of the proper overlap for an in-dividual sprinkler type, and (b) determining the applica-tion rate in order to apply the proper amount of water.
