Thesis ; no. GT-85-17 A thesis submitted in partial fulfillment of the requirements for the degree of Master of Science, School of Engineering and Technology Thesis (M.Sc.) - Asian Institute of Technology, 1986 Electric resistivity interpretation in shallow groundwater surveys relies on an understanding of electrical anomalies caused by specific earth structures such as gravel lenses, buried channals etc. The numerical calculation of such anomalies by approximate techniques is especially important because of the limitations of analytic methods and the inconvenience of laboratory modelling programs. A finite element method computer program (develop by Rijo 1974-1975) capable of handling dipole-dipole resistivity modelling of 2D earth structures is used in conjunction with the plotting methods of combined modified pseudo depth sections to develop and test improved resistivity interpretation techniques for shallow groundwater investigations.
