Graduate student researcher Olasunkanmi Olorunsaye has received the prestigious Graduate Student Grant Award and the Outstanding Mention Award from the Geological Society of America (GSA).

His award-winning research, titled “Using Grain Size Analysis to Incorporate Realistic Hydraulic Conductivity Fields in Beach Groundwater Models,” explores how geological variations influence the flow of water through coastal aquifers.

This work is a key part of a broader effort to better understand and manage freshwater resources in coastal regions, which face increasing pressure from rising sea levels and human activity.

Olorunsaye’s work focuses on incorporating sediment grain size variability into groundwater flow models to improve predictions of freshwater and saltwater interactions. Coastal aquifers, which provide water for millions of people, are increasingly threatened by saltwater intrusion and overuse. His findings enhance the accuracy of groundwater models, offering solutions for protecting these resources.

This research is conducted as part of a project funded by the National Science Foundation (NSF), led by Dr. James Heiss. The NSF project examines the movement of water and dissolved chemicals between land and sea, focusing on how tides, currents, and density differences drive these exchanges. Olorunsaye’s contributions add a crucial layer to this effort by addressing how geological factors shape these interactions, bridging gaps in existing models and knowledge.

Awarding the prize to Olorunsaye, the GSA president, Dr. Gabriel Little praised the research for its originality, noting its potential to guide water management strategies. “This recognition motivates me to continue advancing research that helps protect freshwater resources and maintain ecosystem balance,” Olorunsaye said.

Coastal regions, home to 21 of the 30 world’s largest cities, depend on the health of their aquifers. Research like Olorunsaye’s provides the tools needed to address pressing issues and offers solutions that is globally applicable.
