Delimitación de zonas con potencial de recarga hídrica en la quebrada “la zapata.” del cantón Santa Rosa.

Abstract

The research was carried out in the micro watershed of the "La Zapata" Ravine, located in the canton of Santa Rosa, province of El Oro, Ecuador, in order to identify areas with water recharge potential and properly manage the micro-basin to conserve the availability of the water resource. Using GIS tools together with spatial data, the Matus methodology was applied, considering variables such as slope, native vegetation cover, land use, soil type and rock type to determine areas with water recharge potential that feed aquifers. The results revealed four categories of water recharge potential: the low category, which represents 2.37% of the surface, the moderate category, covering 71,23 % of the area, and the high and very high categories, which together account for 26,39 % of the area. The latter are the most important, as they allow the infiltration of water into the soil and the recharge of aquifers.
