The aim of the project is to simulate the evolution of aquifers at a regional and local scale with 3D Finite Elements models. The simulation at the regional scale was performed with the aid of M3E-FLOW3D, a three-dimensional groundwater flow model developed and updated by M3E team. At the local scale, the model was built using the SUTRA code, a three-dimensional groundwater flow and transport finite elements model simulation. The modeling results were included in a GIS database to promote data sharing with partners and stakeholders and improve the production of thematic maps.
