MAPA DE VULNERABILIDAD HIDROGEOLÓGICA DE UNA PARTE DEL VALLE CENTRAL DE COSTA RICA

Abstract

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.
