Mapping of Potential Groundwater Using Electrical Resistivity Imaging (ERI) at Low Land Area of Parit Raja Johor

Electrical Resistivity Imaging (ERI) has emerged as an important technique in geophysical surveys for gaining more information and locating hidden water. This method was used at Parit Raja, Johorto investigate the location of underground water storage. Two-dimensional (2D) geoelectrical imaging been this study. The three different locations study area to identify potential aquifer suitable boreholes that would serve observation wells. A Schlumberger array set up during data acquisition since it can imagine deeper profile areas with a homogeneous layer. For 2D subsurface images, raw were processed RES2DINV software. According ERI results, dominant low resistivity values less than 10 Ωm shallow depths ranging from 30 m. Furthermore, chargeability value obtained Induced Polarization (IP) supported point. IP data, point between 0 1 ms, indicating presence groundwater area.
