Karst dissolution structures present a global challenge, particularly in urban settings, impacting water resource management and infrastructure stability. Damage prevention and monitoring of these structures often involve identifying them before they manifest at the ground surface. Geophysical methods offer a cost-effective means to noninvasively identify and monitor these structures. This study integrates multiple geophysical techniques, including electromagnetic (EM) and seismic methods, with direct geotechnical coring to identify karst dissolution features in an urban wellfield in South Florida. Our geophysical and geotechnical results show good agreement and suggest the presence of a water-filled dissolution feature or potential sinkhole near the location of a previously detected slurry pond leak. The study underscores the importance of noninvasive exploration methods in karst assessment for sustainable urban development and water resource management strategies.
