Lay summary
A comprehensive strategy is proposed for the extending the characterization of surficial aquifers from the local to the regional scale based on the quantitative integration high-resolution geophysical and hydrological data followed by upscaling and forward/inverse hydrological modeling. The objective of this research is to develop methodologies that are capable of providing aquifer-scale permeability models that are sufficiently detailed and accurate to allow for a faithful reproduction of the pertinent flow and transport phenomena. This type of information is critical for the protection, remediation and sustainable management of the increasingly scarce and fragile groundwater resources in densely populated and/or highly industrialized regions throughout the world. The proposed research focuses on the common case of alluvial aquifers, but with suitable modifications can be extended to karstic or fractured "hardrock" aquifers. High-resolution geophysical methods have the potential to bridge the inherent gap in terms of spatial resolution and coverage that exists between traditional hydrological methods, such as core analyses and tracer or pumping tests. Recently, significant progress has been made regarding the quantitative integration of geophysical and hydrological data at the local scale. Extending this approach to the regional scale does, however, represent a major, and as of yet largely unresolved, challenge. This project aims at addressing this problem based on a workflow involving the following interrelated steps: (i) definition of the large-scale structure of the aquifer in terms of the prevailing flow units and their average hydrological properties (ii) detailed local-scale characterizations of the porosity/permeability structure at multiple locations throughout the aquifers, (iii) upscaling of this local-scale information to the regional scale, and (iv) flow and transport simulations of pertinent hydrological data. The validity and effectiveness of the proposed characterization approach will be explored and tested on an intensively studied aquifer in a suburban region of Québec City, Québec, Canada, suffering from a severe contamination problem and, probably to lesser extent, through corresponding targeted numerical models. This will allow for a systematic assessment of the potential of the proposed methodologies and provide valuable information with regard to the optimal experimental procedures.

Abstract

A comprehensive strategy is proposed for the extending the characterization of surficial aquifers from the local to the regional scale based on the quantitative integration high-resolution geophysical and hydrological data followed by upscaling and forward and inverse hydrological modeling. The objective of this research is to develop methodologies that are capable of providing aquifer-scale permeability models that are sufficiently detailed and accurate to allow for a faithful reproduction of the pertinent flow and transport phenomena. This type of information is critical for the protection, remediation and sustainable management of the increasingly scarce and fragile groundwater resources in densely populated and/or highly industrialized regions throughout the world. The proposed research focuses on the common case of alluvial aquifers, but with suitable modifications can be extended to karstic or fractured “hardrock” aquifers. High-resolution geophysical methods have the potential to bridge the inherent gap in terms of spatial resolution and coverage that exists between traditional hydrological methods, such as core analyses and tracer or pumping tests. Recently, significant progress has been made regarding the quantitative integration of geophysical and hydrological data at the local scale. Extending this approach to the regional scale does, however, represent a major, and as of yet largely unresolved, challenge. This project aims at addressing this problem based on a workflow involving the following interrelated steps: (i) definition of the large-scale structure of the aquifer in terms of the prevailing hydrostratigraphic units and their average hydrological properties (ii) detailed local-scale characterizations of the porosity/permeability structure at multiple locations throughout the aquifers, (iii) upscaling of this local-scale information to the regional scale, and (iv) production-history-matching-type flow and transport simulations of pertinent hydrological data. The validity and effectiveness of the proposed characterization approach will be explored and tested on an intensively studied aquifer in a suburban region of Québec City, Québec, Canada, suffering from a severe contamination problem and, probably to lesser extent, through corresponding targeted numerical models. This will allow for a systematic assessment of the potential of the proposed methodologies and provide valuable information with regard to the optimal experimental procedures.
