Project ISF-DUIRI: Characterization of river discharge and interaction with shallow groundwater aquifers along the Wabash River Program DUIRI - Discovery Undergraduate Interdisciplinary Research Internship Term Fall 2025 Status Accepted Research Area Global Sustainability Description The Wabash River flows through the Greater Lafayette Region in Tippecanoe County, Indiana, playing a critical role in the ecosystems along the river and supporting exchanges with aquifers connected to the river that provide drinking water for residents. However, the characteristics of the groundwater aquifers that supply the baseflow to the Wabash River and their interaction with the river water are poorly studied. By integrated analysis of the continuous recordings from seismic stations and piezometers at multiple sites near the Wabash River and its tributaries, this project aims to calibrate the seismic and hydrologic signatures of the spatiotemporal variations in river discharge and groundwater levels. The outcome of this project will provide a novel and multidisciplinary way of monitoring river discharge and groundwater response in nearby shallow aquifers. The students have the option to receive research credits. Supervisor Xiaotao Yang Mentor Marty D Frisbee Type of work required • Learn basics in seismic and hydrologic data collection
