Project location: Blom Almond Orchard in Modesto, CA (LDRD project from 2016 – 2018)

The goal of the AgMAR project was to understand how the applied flood water was infiltrating into the subsurface by monitoring the infiltration with time-lapse electrical tomography (ERT) and Deuterium tracers. In addition, ERT, full-waveform seismic, and soil cores were used to characterize the subsurface beneath the flooded portion of the orchard.
