Application of Electrical Resistivity Tomography in Groundwater Exploration

Thesis Abstract

Abstract
This thesis explores the application of Electrical Resistivity Tomography (ERT) in the field of groundwater exploration. Groundwater is a vital natural resource that plays a crucial role in sustaining ecosystems and meeting human water needs. However, its exploration and management present challenges due to the underground nature of aquifers. ERT is a geophysical technique that has gained popularity in recent years for its ability to provide valuable subsurface information non-invasively. This study aims to investigate the effectiveness of ERT in mapping groundwater resources and delineating aquifer characteristics. The introductory chapter provides an overview of the research background, problem statement, objectives, limitations, scope, significance, structure of the thesis, and definition of key terms. The literature review chapter critically examines existing studies on ERT applications in groundwater exploration, highlighting its benefits, limitations, and key considerations. The research methodology chapter outlines the approach adopted in this study, including data collection, field procedures, data processing, and interpretation techniques. The findings chapter presents the results of the ERT surveys conducted in selected study areas, showcasing the effectiveness of ERT in mapping subsurface resistivity variations associated with groundwater presence. The discussion section analyzes the implications of the findings, compares them with existing literature, and discusses the practical implications for groundwater exploration and management. The conclusion chapter summarizes the key findings, discusses the implications for future research and applications, and offers recommendations for maximizing the potential of ERT in groundwater exploration. Overall, this thesis contributes to the growing body of knowledge on the application of ERT in groundwater exploration. The findings highlight the potential of ERT as a valuable tool for mapping aquifer structures, identifying potential groundwater zones, and assessing groundwater quality. By integrating geophysical and hydrological data, this research offers insights into the use of ERT for sustainable groundwater management practices. This study underscores the importance of utilizing innovative geophysical techniques like ERT to address water resource challenges and promote sustainable development.
