Integrated Geophysical and Geotechnical Assessment of Subsurface Stability for Sustainable Infrastructure Development on Moheshkhali Island, Bangladesh

Abstract

Rapid development in Moheshkhali Island demands a clear understanding of subsurface conditions to ensure resilient infrastructure. This study integrates Electrical Resistivity Tomography, seismic reflection interpretation, and geotechnical investigations (SPT and laboratory testing) to assess near-surface lithology, deep structural features, and soil engineering properties. The combined approach provides a comprehensive subsurface stability profile, identifying variations in soil strength and tectonic influences. Findings offer essential guidance for planners and engineers in designing safe, sustainable infrastructure for Moheshkhali Island’s ongoing development.
