Site characterization is essential for informed decision-making in fields such as environmental management, civil engineering, and resource exploration. This manuscript explores the integration of various geophysical methods to enhance subsurface investigations, emphasizing their principles, methodologies, and practical applications. The study presents five localized case studies from Nigeria, demonstrating the effectiveness of integrating techniques such as Electrical Resistivity Imaging (ERI), Ground Penetrating Radar (GPR), Seismic Refraction, and geotechnical testing. Each case study addresses specific challenges, including groundwater contamination assessment, structural integrity evaluation, and aquifer identification. The findings highlight that an integrated approach improves data quality, enhances interpretation accuracy, and supports sustainable resource management. The manuscript concludes by discussing future directions in geophysical methods, including advancements in technology, interdisciplinary collaboration, and the importance of regulatory frameworks. Overall, this work underscores the critical role of integrated geophysical methods in comprehensive site characterization and their potential to inform effective environmental and engineering practices.
