3D Geological Modeling of Saïss Basin (Northern Morocco)

The Moroccan septentrional region includes the Bassin du Saïss. Due to this bassin's enormous surface area and substantial depth, our current understanding of it is still limited and fragmentary. To improve understanding of the aquifer, a 3D geological model was developed using data from over two hundred boreholes, eight geological maps, and a digital terrain model. The data was processed using a Geographic Information System (GIS) and a geological modeling software, with consideration given to five lithostratigraphic units: Paleozoic, Triassic, Jurassic, Miocene, and Plio-Quaternary. The developed model provides a precise visualization of the geometry and stratigraphy of the basin, as well as a better understanding of the deep Lias aquifer and its hydrogeology. The study results provide a valuable conceptual model that can be used to reinterpret existing geophysical data and assess the extent of the Lias aquifer. Furthermore, the results can contribute to the development of a hydrogeological model that simulates the hydrodynamic functioning of the aquifer under variable climate and exploitation conditions.
