Heat as a proxy to image dynamic processes with 4D electrical resistivity tomography [PDF]

open access: yes, 2019
Since salt cannot always be used as a geophysical tracer (because it may pollute the aquifer with the mass that is necessary to induce a geophysical contrast), and since in many contaminated aquifer salts (e.g., chloride) already constitute the main ...
