Diseño agronómico e hidráulico del sistema de riego parcelario del Proyecto Chambo-Guano, Fase II, para el Módulo 4 en la comunidad Chingazos, cantón Guano.

Abstract

The objective of this work was to elaborate the agronomic and hydraulic design of technified irrigation in module 4 in Chingazo Alto. The project is located at Latitude: 1°37'7" S and Longitude: 78°34'39" W, it has 38.44 gross hectares with 35.54 net hectares. The proposal was to elaborate: Base studies, Complementary studies, Agronomic design, Social study, Agroeconomic study, Financial study, Hydraulic design, Budget and Technical specifications. The topography was transcendental to develop the hydraulic approaches, the water requirement was 3.02 mm day-1, the soils were sandy loam that allowed to have a gross lamina of 22.10 mm and an average infiltration rate of 87.25 mm h-1. The proposed emitter was a mini-sprinkler of 0.07 L s-1 , whose operating time was 3 hours every 7 days. The crops were: corn, strawberry, alfalfa, lemon, blackberry and prickly pear. The hydraulic designs were sectorized in 12 modules, the flow rate for module 4 was 34.10 L s-1, in this sense, irrigation will be carried out during the day with 12 hours of system operation. The social study was prepared for the conditions of the 86 families, where it was confirmed that agriculture does not represent an economic activity that generates resources and basic services lack attention. It is concluded that the study area is suitable for an irrigation project with the proposal to implement lemons to generate resources with technification, thus, an increase in family income from US$ 411 to US$ 1544 per year is expected. In addition, the financial indicators were: Internal Rate of Return (IRR) 19.38%, Net Present Value (NPV) 155471, Benefit/Cost (B/C) 1.26 and Payback Period (PRI) 8.04 years. The total budget was US$ 515895.67 with investments per family of US$ 5998.79 and per hectare of US$ 14515.92.
