“…centimeters and the spatial resolution is too coarse (Robinson et al, 2012). At intermediate scales (decameter to hectometer), geophysical techniques, such as electromagnetic induction (EMI), ground penetrating radar (GPR) and electrical resistivity tomography (ERT), have proven to be promising alternatives to infer soil water down to several meters (e.g., Huisman et al, 2003;Brunet et al, 2010;Robinson et al, 2012;Steelman et al, 2012;Brillante et al, 2014). EMI is useful for mapping the horizontal distribution of subsurface electrical resistivity, but it gives little information on its vertical distributions (Robinson et al, 2008).…”
