Description
Este trabajo presenta el mapa de vulnerabilidad hidrogeológica de una parte del Valle Central deCosta Rica, donde se concentra la mayor parte de la población del país, se desarrolla gran parte de la industria,agricultura y otros procesos productivos que impactan de forma negativa a los recursos subterráneos. Se utilizó el método de DI-O-S, que se basa en el producto de tres parámetros: ocurrencia del agua subterránea, sustratolitológico y profundidad del nivel de agua subterránea. Se puede observar que las áreas de mayor vulnerabili-dad hidrogeológica se localizan al norte y este del Valle Central. Estas zonas, deben investigarse con mayordetalle, para ser consideradas en los planes de ordenamiento del territorio.
This work presents a hydrogeological vulnerability map of a part of Valle Central in Costa Rica.The study area is characterized by a high density urban population, where the presence of industry and agricul-ture negatively impact the groundwater resources. The DI-O-S method was used to define the hydrogeologicalvulnerability, based in three factors: type of aquifer, lithology and depth of groundwater level. The zones with high vulnerability are located to the North and East sides of the Valle Central. These zones must be investigated in great detail to be considered in further urban management plans.
