In the programming of the irrigation rolls, under the modality of tumo or mita, one of the considerations to consider is the time of route of the water in the title channels of supplying, which, it is in function to the hydraulic characteristics of the channels and the state of the maintenance of these. This time assigned by the technical part in the programming of the irrigation rolls, manual or executed by means of sorne software, it is considered empirically so that they do not count on sorne real data base or a prediction source andor estimation of he himself, thus influencing in the dowry of water the irrigation users. To consider the time of route of the water in channels, is advisable to use the basic concepts that govern the determination of the curve of advance and resection in furrows; because this behavior is itself in hydraulic sections governed by the same characteristics (infiltration, slope, section); being its curve of tendency or potential regression defined by the values ofits constants (a=constant ofshape, b=slope ofthe curve). The procedure to determine the advance curve consisted ofthe taking of data ofthe time of arrival of the flow in function to the advance distance, described by the hydraulic characteristics and the state of maintenance in which was each channel. The sample was statistically analyzed according to the behavior of the variables that participate in this phenomenon, with the help of"Software SPSS vs. 11.0". The present work ofinvestigation was made in the Santa Elena's Irrigation Commission of Virú valley, the representative sample was the family of channels who conforms this COffiffilSSlOn. As result obtained a data base of the behavior of 22 channels without covering, and a characterization of the curves of advance of the channels according to its hydraulic and ph y si cal eh aracteri sti es Was concluded that the time of advance of the flow of the water in channels without covering, behaves under regime of its hydraulic and physical characteristics, influenced mainly by the slope and the severed (been ofmaintenance ofthe channel).
