Abstract
A comprehensive computer model, HEDIA, was created to simulate sprinklers water overlapping patterns theoretically by one sprinkler superimposition technique under selected layout design. This model can also calculate uniformity coefficients, application efficiency, storage efficiency and deep percolation by linear and normal distribution fit. Lab tests were established to verify HEDIA model. Their results indicated that HEDIA model accurately simulates sprinklers overlapping patterns shapes of square, rectangle and triangle and gets coefficients of determinations (0.97), (0.98), and (0.98) respectively compared with actual data. Moreover, analysis of variance by randomized complete block design for actual and simulated data of uniformity coefficients, linear and normal for water performance efficiencies were not significant at 1 % confidence under the three shapes of overlapping patterns separately. Correlation between actual and simulated data of water performance efficiencies by linear and normal distribution fit for square, rectangle and triangle overlapping shapes got coefficient of determination of [(0.98, 0.99), (0.99, 0.99), (0.99, 0.99)], respectively for storage efficiency and (0.99) for application efficiency in all overlapping shapes fits. So, HEDIA computer model was proved to be reliable and could be used confidentially to simulate overlapping patterns performance parameters.
