Thesis Abstract

Abstract
This thesis explores the integration of Ground-Penetrating Radar (GPR) and Electrical Resistivity Tomography (ERT) techniques for subsurface imaging applications. The study aims to demonstrate the effectiveness of combining these geophysical methods to enhance subsurface imaging capabilities and provide valuable insights into the geological structures and properties of the subsurface. The integration of GPR and ERT offers a comprehensive approach to subsurface investigations by utilizing the complementary strengths of each method to overcome their individual limitations. The research begins with a comprehensive literature review that examines the principles, applications, and limitations of GPR and ERT techniques in subsurface imaging. This review forms the basis for establishing the theoretical framework for the integration of GPR and ERT and highlights the potential benefits of combining these methods for enhanced subsurface characterization. The methodology chapter outlines the research design and data collection procedures for conducting the integrated GPR and ERT surveys. The study includes field experiments conducted in selected test sites to acquire geophysical data that are processed and analyzed using advanced data processing techniques and inversion algorithms. The integration of GPR and ERT data sets allows for the generation of high-resolution subsurface images that provide detailed information about the geological structures and properties of the subsurface. The findings chapter presents the results of the integrated GPR and ERT surveys and discusses the interpretation of the subsurface imaging data. The study demonstrates the effectiveness of combining GPR and ERT techniques in enhancing subsurface imaging capabilities and improving the resolution and accuracy of subsurface models. The integrated approach offers valuable insights into the subsurface geology, including the detection of buried objects, mapping of geological interfaces, and characterization of subsurface materials. The discussion chapter critically analyzes the findings and discusses the implications of the integrated GPR and ERT approach for subsurface imaging applications. The study highlights the advantages of combining GPR and ERT techniques, such as improved resolution, depth penetration, and spatial coverage, compared to using either method individually. The discussion also addresses the challenges and limitations of the integrated approach and proposes recommendations for future research and development in the field of geophysics. In conclusion, the thesis summarizes the key findings and contributions of the study and emphasizes the significance of integrating GPR and ERT techniques for subsurface imaging applications. The research demonstrates the potential of the integrated approach to provide valuable information for various geotechnical, environmental, and archaeological investigations. Overall, the study contributes to advancing the field of geophysics by showcasing the benefits of combining complementary geophysical methods for enhanced subsurface imaging and exploration.
