Current Projects

The Future of Energy and Minnesota's Water Resources
Minnesota's future water resources considering potential changes in demographic distribution, energy production and consumption and climate change are analyzed combining GIS mapping, scenario development and water budget analysis.

Spatially Explicit Water Budget Analysis Using GIS-based Stocks-and-Flows Model
This study aims to establish a GIS-based Water Stock-And-Flow model (GWSTAF) which incorporates up-to-date GIS data sources and technology for establishing a state-level water budget model. This approach illustrates spatial feature of water balance and determines the magnitude of anthropogenic impacts on water deficit in Minnesota.

Minnesota Corn Ethanol Water Use Impact
Collaborating with ETH Zurich, the newly established water use impact assessment model is incorporated to bridge water use quantity and its consequential impacts. The study uses Minnesota's corn-based bioethanol as an example to demonstrate different implication of water use in terms of environmental impact. A life cycle impact assessment compatible factor is employed to quantify the ecological damage associated with ethanol water consumption.


The Water Sustainability Group aims to enhance collaboration among water interests, scholars, and agencies, and policy makers. Using a multidisciplinary approach in order to comprehensively integrate knowledge and technology in sustaining water resources, We've been working closely with the international and regional water authorities, institutes, and active experts. A working group comprising a series of Water Implication Forum discussions of interested parties is hosted quarterly, the purpose of which is to make available share cutting-edge technology across research communities.
