Instrument and method: SuperStingR8 WiFi with 28 electrode passive electrical imaging cable. Measured in dipole-dipole and inverse schlumberger array. Modeled with EarthImager 2D.
Results: Resistivity data were used to successfully estimate the thickness of a soil layer that was added to retain moisture and allow grass to grow. The location of a concrete foundation was determined and also the extent that roots have grown outwards from several trees.
