The use of Electrical Impedance Tomography (EIT) to map subsurface hydraulic conductivity. EIT can be used to map hydraulic conductivity in the subsurface where measurements of both amplitude and phase are made. Hydraulic conductivity depends on at least two parameters: porosity and a length scale parameter....http://www.google.es/patents/US6147497?utm_source=gb-gplus-sharePatente US6147497 - Using electrical impedance tomography to map subsurface hydraulic conductivity
