Quantifying Storage in Regional Great Lakes Watersheds Using GRACE,MODIS Products and Coupled Subsurface - Land Surface Process Models
Abstract
Watershed storage is a fundamental variable that controls the hydrologic function of a watershed. Storage is intimately tied to surface and subsurface stormflows and runoff ratios in a watershed and is important for understanding climate change impacts on water resources. Here we estimate storage and water budgets in regional Great Lakes watersheds using remotely-sensed data and a process-based hydrologic model that includes detailed representations of subsurface and land surface processes. We also analyze the effect of grid resolution on storage and compare model results of storage with GRACE product equivalent water thickness and analyze water budgets using the Budyko framework for sub-basins based on topography, land use land cover and subsurface storage capacity.
