AbstractIn the Montérégie region, east of Montreal, Quebec, Canada, high-resolution compressional (P-) and shear (S-) wave reflection sections were obtained using a vibratory source and 3-component (3-C) landstreamer data acquisition system during field programs carried out in 2009 and 2010. The work was part of a strategy to improve the knowledge and understanding of groundwater resources within the glacial and post-glacial sediments in the region. The >100 line-km of seismic profiling is an excellent example of hydrogeophysics, providing detailed information on the depth to bedrock, the architecture and stratigraphy, and physical properties of the overlying sediments on both the regional and local scales (hydrostratigraphic mapping), as well as insights into fluid (water and/or gas) transport through the surface aquitard. Correlations of porosity and shear wave velocity in the region also allow some estimation of the variation in subsurface porosities for hydrogeological modeling.
