 Hydrogeological maps must combine scientific knowledge about the hydraulic features and the hydrogeological behavior of a given area with the needs of land planners and administrators. To be effective, these maps should be designed specifically for each unique situation, taking into account the interconnectedness of various components such as rivers, streams, and aquifers. This case study demonstrates how a hydrogeological map can be designed to synthesize multiple contexts, including an alluvial aquifer, a hydrographic basin, and hard rock aquifers. It also includes a modeling map, a sketch of an artificial channel network, and a hydrogeological profile. The map combines all of these elements to provide a comprehensive view of the interconnectedness of the various components, allowing for better understanding of the overall system.
