Performance of basin irrigation in the Lower Tunuyán River in Mendoza, Argentina

This paper results from the evaluation of irrigation in 37 different basins planted with perennial crops in the oasis irrigated by the Lower Tunuyan River in Mendoza, Argentina. The basins were evaluated by calculating management parameters through volumetric analysis. The results of this analysis were compared with the values obtained by means of the BRDRFLW mathematical model (Strelkoff, 1985). Four main elements were considered for analysis: application efficiency (ea), cut-off time (Tco), length (L), and net depth (DR), Multiple correlations were established and transferred to the graphics, which are simple and suitable for use by extensionists and farmers interested in improving basin irrigation efficiency.
