Una función para la gestión hidrosistémica: programación de riegos, demanda y capacidad de conducción de canales

Introduction: The management of irrigation areas aims to achieve an efficient use of resources for full user satisfaction. Objectives: To propose a methodology for hydrosystemic management in which crop demand, irrigation planning in the allocation and distribution of water, as well as conduction capacity concur. Methodology: A hydrosystemic management function was developed in which the variables of interest, consisting of six stages, concur and the “Santa Rosa” irrigation module of irrigation district 075, Sinaloa, Mexico, was evaluated. A maximum ten-day water demand requirement was estimated, with an established area of 22 518 ha and a maximum irrigation demand area of 13 548 ha. Results: Irrigation distribution planning in the evaluated module requires a maximum flow of 27.18 m3∙s-1, being satisfied with the canal capacity (27.87 m3∙s-1), and a maximum ten-day volume of 11 million m3. Study limitations: Only the controlled demand distribution method was used, since it is employed in irrigation districts in Mexico. Originality: The variables of an irrigation area are analyzed and implemented together, which will facilitate the integrated operation of large agricultural hydrosystems. Conclusions: The application of the proposed management instrument will facilitate water delivery according to the controlled demand distribution method in Mexico’s irrigation districts.
