Add Tag | Summary: | Water is an essential component for the survival of mankind, and its availability is a determining factor for social and economic progress, especially in rural areas, where enormous quantities of this resource are needed for the proper development of crops. The importance of water in agriculture drives the search for viable technical, economic, and social solutions that allow water harvesting and storage. The construction of properly waterproofed earth reservoirs enables the farmer to have water available during a drought when this resource is scarce. This research seeks to contribute to improving rainwater storage and harvesting through the design and construction of a clay-waterproofed reservoir in the Chuquiribamba Parish of Loja Canton. The study area is in the Sacapalca geological formation; the soil is dedicated to protection with 4.17%, has slopes between 15% and 35%, has an average annual temperature of 12.24 oC, and average rainfall ranges from 800 to 1,300 mm. Concerning the physical-mechanical characteristics of the clays, they have a moisture content of 30.64% in their natural state; they are fine-grained soils (highly compressible silt and clay) with a maximum density of 1.15 g/cc and an optimum moisture content of 43%. The hydraulic conductivity determined in the laboratory and scales between 1.10x 10-8 , 2.47x 10-8 , and 1.09x 10-8 cm/s, correspond to values of very slow velocities belonging to compacted clays. The permeability evaluated in the field in the reservoir waterproofed with the material studied shows infiltrations of 2.41 x 10-5 cm/s. In conclusion, the reservoir waterproofed with clay facilitates water accumulation during rainy periods, allowing its subsequent use in agriculture or for animal consumption during droughts. |
