Thesis Overview

The project titled "Application of Seismic Reflection and Refraction Methods for Subsurface Imaging in an Urban Environment" aims to investigate the effectiveness of employing seismic reflection and refraction methods for imaging subsurface structures in urban settings. Urban environments present unique challenges due to the presence of infrastructure, utilities, and other man-made features that can complicate traditional geophysical surveying techniques. By utilizing seismic reflection and refraction methods, this research seeks to overcome these challenges and enhance the understanding of subsurface conditions in urban areas. The research will begin with a comprehensive review of relevant literature to establish the existing knowledge and gaps in the field of geophysical imaging in urban environments. This literature review will cover topics such as the principles of seismic reflection and refraction, previous studies on subsurface imaging in urban areas, and the advantages and limitations of these methods in such settings. Following the literature review, the research methodology will be outlined, detailing the data collection techniques, equipment used, data processing procedures, and interpretation methods. Special attention will be given to the specific challenges faced when conducting seismic surveys in urban areas, such as background noise, limited access to certain areas, and the need for high-resolution imaging. The core of the research will involve conducting field surveys using seismic reflection and refraction methods in selected urban locations. Data collected from these surveys will be processed and analyzed to create subsurface images that provide insights into the geological structures and potential hazards present beneath the urban environment. The findings will be compared with existing geotechnical data and ground truthing to validate the accuracy and reliability of the imaging results. The discussion of findings will focus on interpreting the subsurface images generated through seismic reflection and refraction, identifying key geological features, anomalies, and potential risks that may impact urban development and infrastructure stability. The implications of these findings for urban planning, construction projects, and risk assessment will be highlighted, emphasizing the importance of incorporating geophysical imaging techniques in urban development projects. In conclusion, this research will contribute to the advancement of subsurface imaging techniques in urban environments by demonstrating the applicability and effectiveness of seismic reflection and refraction methods. The insights gained from this study will aid in improving the understanding of subsurface conditions in urban areas, ultimately leading to more informed decision-making processes and enhanced infrastructure resilience in urban settings.
