Abstract The complete fluidic sprinkler was originally developed in China.A software was presented to analyze the data of water distribution.The data can be made visible in multidimensional orientation as a result.By using MATLAB it was proved that the radial data can be changed into net data conveniently and reliably.Three-dimensional water distribution pictures for sprinkler and combined sprinklers were drawn by MATLAB.According to the test data,the total water depth of net point was calculated using superposition method.Then the combined uniformity coefficient of the complete fluidic sprinkler was simulated in different combined spacings.After the simulation,combined spacing coefficient was chosen as 1.2 in the rectangular combination,and 1.5 in the triangular combination.The average uniformity coefficients are 82.4% and 85.7% respectively.A case study shows that MATLAB is reliable for simulating water distribution in sprinkler irrigation.
