Johan Alexander Huisman - Vadose Zone Hydrogeophysics (Presentation)

This presentation was presented during the 4th Cargèse Summer School on Flow and Transport in Porous and Fractured Media in 2018. Don’t hesitate to have a look on other lectures of the summer school on our channel!

Hydrogeophysical measurements are useful to investigate the interaction between structural heterogeneity of vadose zone properties and water flow and transport processes. Structural characterization will be illustrated using results of a 1 km2 survey with electromagnetic induction measurements within the context of precision agriculture. Vadose zone processes can be investigated using time-lapse geophysical measurements. Although it is attractive to integrate such time-lapse measurements of varying origin, scale, and uncertainty into hydrological models, this is a far from straightforward task. After an introduction of the challenges of such model-data integration, the possibilities and limitations of coupled inversion approaches will be discussed. The presentation will end with my personal opinion on future research needs for hydrogeophysics.
