This five-year, $800,071 Project Grant from the National Science Foundation's Geosciences program (CFDA 47.050) supports the development of an integrated hydrologic model to better understand groundwater dynamics in the Great Lakes Basin. The awardee, Michigan Technological University, will fuse hydrologic modeling with GPS, satellite imagery, and GRACE data to more accurately simulate surface and subsurface flows. Through data assimilation, the project will produce historical and forecast groundwater flow and storage datasets to reveal the spatial and temporal distribution of groundwater across the basin and relate this to fluctuating lake levels. This integrated modeling approach provides an unprecedented view of how groundwater storage affects Great Lakes levels. The products will deliver reliable information on surface and groundwater resources needed to support water management in the region.
