AbstractA general workflow is proposed to characterize hydraulic properties of unconsolidated aquifers from geophysical data. Three-dimensional hydraulic property models are essential for groundwater flow and solute transport studies aimed at assessing water resources sustainability. Spatial coverage offered by conventional hydraulic characterization approaches based on hydraulic tests in wells are; however, often limited due to the time required to perform hydraulic tests, especially when high-resolution and/ or large complex areas need to be characterized. On the other hand, geophysical surveys can reveal important architectural features of an aquifer system; however, the quantification of geophysical attributes into hydraulic properties is difficult to achieve under field conditions. To overcome those limitations, a hydrogeophysical approach based on the definition of site-specific relationships between collocated geophysical and hydraulic data is proposed to allow the translation of geophysical attributes into hydraulic properties. The development and application of this approach that is currently underway for the Vars-Winchester esker system in south-east Ontario is reported here.
