Characterization of reactive transport by 3-D electrical resistivity tomography (ERT) under unsaturated conditions [PDF]

open access: yes, 2016
The leaching of nitrate from intensively used arable soil is of major concern in many countries. In this study, we show how time lapse electrical resistivity tomography (ERT) can be used to characterize spatially heterogeneous processes of ion production,
