Abstract

The Zapotillo irrigation project is considered one of the largest and most important investments being made by the Ecuadorian state for the benefit of the southern region and the country; With a total gross area to be incorporated into irrigation agriculture of 13,000 ha, which is what is being achieved agricultural and livestock development of this area, thus increasing trade and improving the living status of this population. The waters that will serve to irrigate approximately 10,000 ha are taken from the Catamayo River for a flow of 8.20 m3Is, which are conducted by a transfer of 14.00 km along the margin of the river Alamor and Chira, later subdivided into two branches that are both Conduction IC as 20; The first irrigates the left bank of the river Alamor; The section of the open channel is trapezoidal with slopes 4: 1, and capacity of 6.72 m 3 / s; The second one has a length of 32.6 km. It consists of an open, trapezoidal channel with 4: 1 slopes. The 3DC line of the Zapotillo irrigation system starts at the abscissa 22 + 400 of the line 10, with a length of 93.34 Km, carrying a flow Of 5121 l / s, and irrigates an area of ​​5,180.80 Ha on the right bank of the Chira river. The climate in the area of ​​the project is one of the most outstanding, due to its low rainfall, its high luminosity, and its constant temperature that oscillates between 230 and 26 ° C; And rainfall of 500 to 1000 mm per year, which makes it practically a natural greenhouse. This, together with a safe water supply, will allow for the studies carried out a sustained development of crops such as mango fruit, limon; Annual cyclic crops of rice, onion, vegetables, among others.
