Enhanced Peat Profiling with Electrical Resistivity Tomography and Multichannel Analysis of Surface Wave

Infrastructure development into peat necessitates geotechnical engineers to find a better profiling method. The conventional profiling carried out by either a localized peat augering or a borehole drilling is often subjective, lacking of details, time consuming and high cost. This paper present...
