Abstract
Linear, normal, and beta statistical models are fit to 2,450 overlapped sprinkler irrigation patterns. The deviations of these three models from the observed water distribution are compared. Of the three, the beta distribution provides the best fit but is presently least practical to use. For uniformity coefficients above about 0.65, the normal model generally fits observed sprinkler distributions better than does the linear model. At lower uniformities, iuniformities, the opposite is true.
