Heterogeneity of hydrogeological and biogeochemical parameters is significant across multiple spatial and temporal scales. Because conventional (wellbore) characterization approaches reflect very localized conditions, they often can’t provide sufficient information across scales needed to develop conceptual models, address scientific questions and aid decisions regarding water resources, contaminant remediation, geotechnical, agriculture and climate resilience. Geophysical data, collected from the airborne, ground surface and/or subsurface sensors, hold promise for rapid, minimally-invasive, and vastly improved characterization and monitoring of hydrobiogeochemistry.
As illustrated by the following links, we are investigating the capability to characterize and monitor changes in hydrological-biogeochemical properties/processes using geophysical measurements at both the laboratory column and the field-scales. Our team is also developing several estimation and machine learning methodologies for use with geophysical data, which permit systematic fusion of multiple sources of information and incorporation of complex petrophysical models across relevant scales.
