The use of FDEM–GCM method in environmental investigation: coastal aquifer case studies

This work presents the results of a research project that it had as motivation to obtain a better knowledge of the seawater intrusion contamination problem of the coastal aquifers in Canoa Quebrada city at coastal zone. The water supply to the coastal zones comes mainly from the coastal aquifers that are represented in the Ceará State by a system composed of dunes/Barreiras Formation/ crystalline. Due to intensive use of these groundwater reserves in the last years as a consequence of accelerated population growth along the coast, these systems are beginning to present signs of exhaustion that are characterized by salt contamination.
