The work was carried out in order to evaluate the distribution of water applied to the plots, pointing out possible causes of waste and suggest solutions to the optimal use of irrigation water. Worked up with flow tests to determine the coefficients of Distribution Uniformity (CUD) and Christiansen (CUC). Obtained is then the graph of uniformity in the profiles of three-dimensional distribution of water in the plots. It also studied the relationship between the flow rates and actual project and the possible causes that led to problems. The results showed that the highest flow rates were observed at the beginning of the lines of issuers and end of the line of derivation. It was also observed that the sheet of water applied is largely of times greater than blade of water designed, presenting, however, points of disability where the blade was less than required in the project.
