dc.descriptionThe irrigation performance of any irrigation systems is highly facilitated when using a fitted model to represent the measured data. Several statistical distribution models, such as uniform, normal, lognormal, specialized power, beta, and gamma, have been used to fit applied water from irrigation, as na aid to evaluate the irrigation performance. However, the goodness of fitting the model to the observed values is very important to warrant reliable results. The purposed model resembles a power function and has desirable flexibilities for adjusting data. It uses four adjusting parameters, conferring to the model a great deal of power to adjust a variety of possible shapes of normally found distribution profiles from water irrigation applications. Its adjusting parameters can be easlily estimated using the "Solver" routine from Microsoft Excel. The new mathematical model is used to represent the applied water to derive the formulations needed to calculate all the necessary parameters for compute uniformities and efficiency measures. Additionally, it is purposed and irrigation factor to adjust a given crop water depht so that the resulting average applied water will match a established goal, defined in terms of the desired amount of fully irrigated area.pt_BR
