The present study aims to evaluate the irrigation efficiencies of the area of influence of the reservoir "Cartavio 26" in the company Cartavio S.A.A. Using two different states of time, in relation to the requirement of water supply in the distribution, for which the method was applied with data collection in the field and systematization of the information. In the field phase, through the inflow and outflow of the "Cartavio 26" reservoir, the results obtained will serve to verify the requirement of the corresponding water supply according to the Water Distribution Plan, as well as determine areas for expansion Of agricultural frontier. It should be noted that the value of driving efficiency depends directly on the texture of the soil where they are located, the conservation status of the ditches and the entire area of influence of the "Cartavio 26" reservoir, as well as the expansion of...
