Application of Electrical Resistivity Tomography in Mapping Subsurface Structures

Thesis Overview

The project titled "Application of Electrical Resistivity Tomography in Mapping Subsurface Structures" aims to explore the utilization of Electrical Resistivity Tomography (ERT) as a geophysical method for mapping subsurface structures. This research endeavors to investigate the effectiveness and applicability of ERT in delineating underground features such as geological layers, faults, fractures, and groundwater reservoirs. The research will begin with a comprehensive review of the theoretical background of ERT, highlighting its principles, instrumentation, data acquisition methods, and processing techniques. This foundational knowledge will provide a basis for understanding how ERT can be employed to image subsurface structures based on variations in electrical resistivity. The project will address the current problem statement in geophysics regarding the need for accurate and non-invasive methods to map subsurface structures for various applications such as environmental studies, mineral exploration, civil engineering, and groundwater management. By focusing on ERT, the research aims to contribute to the advancement of geophysical imaging techniques and their practical applications. The objectives of the study include evaluating the resolution and depth penetration capabilities of ERT, assessing the accuracy of subsurface imaging using ERT data, comparing ERT results with other geophysical methods, and identifying the limitations and challenges associated with ERT surveys in complex geological settings. The scope of the research will involve conducting field surveys using ERT equipment at selected study sites with known subsurface structures. Data collected from these surveys will be processed and interpreted to generate 2D and 3D resistivity models of the subsurface, which will be validated against existing geologic information and borehole data. The significance of this research lies in its potential to enhance the understanding of subsurface structures and improve the efficiency of resource exploration and environmental assessments. By demonstrating the capabilities and limitations of ERT in mapping subsurface features, this study aims to provide valuable insights for geoscientists, engineers, and decision-makers involved in various industries. The structure of the thesis will be organized into chapters covering the introduction, literature review, research methodology, discussion of findings, and conclusion. Each chapter will delve into specific aspects of the research process, from theoretical frameworks to practical applications, culminating in a holistic analysis of the application of Electrical Resistivity Tomography in mapping subsurface structures. In summary, the project on the "Application of Electrical Resistivity Tomography in Mapping Subsurface Structures" seeks to advance the field of geophysics by exploring the capabilities of ERT as a powerful tool for non-invasive subsurface imaging. Through rigorous fieldwork, data analysis, and interpretation, this research aims to contribute valuable insights and practical solutions to the challenges of subsurface structure mapping in geoscience and engineering disciplines.
