"This thesis deals with a theoretical study on the interpretation of resistivity sounding data measured by the Wenner electrode system. The objectives of this investigation are twofold: (i) to derive from the apparent resistivity data some suitable functions from which the resistivity and thickness of each member of the sequence of layers composing the earth may be determined, and (ii) to devise suitable methods for analyzing the resulting functions. In this investigation it is shown that the solution of the boundary value problem associated with an n-layered earth model leads to an integral equation for the Wenner electrode system. This integral equation relates the apparent resistivity function to an unknown function, termed the kernel, which is dependent on the layer resistivities and thicknesses. by solving this integral equation one does not obtain the kernel directly, but rather a related function, termed the associated kernel, from which an explicit integral expression for the kernel can be derived. Formulas for numerical integration are developed for the calculation of both the kernel and associated kernel from apparent resistivity data. These formulas are found to give satisfactory results. A numerical-graphical method is developed for the analysis of the kernel and the associated kernel. A further technique based on the principle of logarithmic curve matching is developed for the decomposition of the kernel alone. These methods are found to yield reasonably accurate values for the layer resistivities and thicknesses"--Abstract, pages ii-iii.
