Aplicación de los Sistemas de Información Geográfica en la identificación del potencial de recarga hídrica de la microcuenca Río Botello

Abstract

The global problems due to the overexploitation of natural sources of water resources, fundamental to satisfy the basic needs of communities where groundwater is their only source or is an alternative supply in drought seasons, have increased the importance of identifying areas that favor the hydric recharge process. Due to the above, this research was proposed in order to determine the water recharge potential within the Botello river micro-basin in the municipality of Facatativá Cundinamarca, through a process of overlapping layers for the weighting of variables such as: slope , soil type, geology, land use and vegetation cover. The development of the research allowed to determine that 74.76% of the area of the Botello River basin presents a moderate potential for water recharge and a 20.90% very low potential; the results mainly reflect that the forest areas that are conserved in the upper part of the basin and the relief conditions are the main factors that favor the process of water infiltration into the soil of the study area.
