Estudio para mejoramiento del sistema hidrotécnico para el proyecto de riego de las comunidades de Cachi y Rumipamba del cantón Girón, provincia del Azuay

Abstract

This work contributes to the development of irrigation in the region through a technical study for the project in the communities of Cachi and Rumipamba in the Girón canton, managed by the Provincial Government of Azuay. The study includes: 1) Biophysical characterization of the project area; 2) Hydrotechnical design for the main conveyance and the secondary distribution network; 3) Economic valuation of the conveyance and secondary distribution of the project. Information gathering, in collaboration with the users, provided key elements for obtaining a current diagnosis of the project and defining the irrigable area. Through a climatological study, the water requirements of the crops considered in the project were determined, with maximum needs identified between the months of June and November, peaking at 3307 m3 /day. For the hydraulic design, the following were considered: i) Design flow of 51.33 L/s, corresponding to a characteristic flow of 0.5 L/s/ha for a total irrigation area of 88.3 ha; and, II) irrigation frequency of 7 days and 12-hour rotating shifts for 12 sectors, with an average of 7.4 ha per user. The pressurized conveyance and distribution system was designed with diameters ranging from 160 to 250 mm for the main conveyance and from 50 to 200mm for the secondary lines. The study includes project plans, a technical report, and the construction budget.
