Groundwater aquifer detection using the electrical resistivity method at Ito Campus, Kyushu University (Fukuoka, Japan)

Abstract An electrical resistivity survey was carried out using the pole–pole configuration around Sayanokami spring area in northern part of Ito Campus (Kyushu University, Fukuoka, Japan) to study groundwater aquifer and its characteristics. A Code Division Multiple Transmission (CDMT) system used. The CDMT transmits 24 currents simultaneously measures potential responses with monitoring actual current waveforms. can inject from multiple electrodes into underground environment different individual two-dimensional (2-D) inversion results data indicate three layers top bottom, as follows: (a) a thin layer thickness 3 m low (< 50 ? m) representing topsoil; (b) an average between 170 ranging 7 10 m, (c) highly resistive bedrock resistivities higher than 200 occupying depths 15 base model.
