ELECTRICAL RESISTIVITY AND SEISMIC REFRACTION METHODS CARRIED OUT AT UTAGBA OGBE TECHNICAL COLLEGE, KWALE, DELTA STATE.
Abstract
This report presents the findings from a comprehensive geophysical investigation conducted at
the site, utilizing both seismic refraction and electrical resistivity surveys to assess subsurface
stratigraphy and geotechnical properties. The seismic refraction method effectively delineated
multiple refracting horizons, revealing significant variations in seismic velocities and densities
across different layers. Concurrently, the electrical resistivity survey provided complementary
data on the subsurface's resistive characteristics, enhancing the overall understanding of
geological conditions. The integration of these methodologies allowed for a more robust
interpretation of subsurface features, which is critical for informing engineering design and
construction practices. Recommendations for further investigations, including additional
geophysical methods and longitudinal monitoring, are provided to ensure a comprehensive
understanding of subsurface lithology conditions and to enhance the safety and stability of
future enviromental assessment projects.
