About the Water Systems Analysis Group

About Us

The Water Systems Analysis Group (WSAG) is located within the Earth Systems Research Center (ESRC) in the Institute for the Study of Earth, Oceans, and Space (EOS) at the University of New Hampshire. We maintain strong collaborations with other departments at UNH, including the Departments of Natural Resources and the Environment, Earth Science, Environmental Engineering, as well as researchers distributed around the country. In understanding the environment as an integrated system, WSAG explores the physical, chemical and biological processes that shape hydrological systems, with emphasis on the unique role of humans as agents of change. Our research and educational programs cross the boundaries of traditional scientific disciplines to foster interdisciplinary understanding of environmental change. Through field monitoring, whole ecosystem experiments, novel in situ sensor deployments, and dynamic hydrological and ecosystem modeling, we attempt to understand hydrological and biogeochemical dynamics at scales ranging from individual ecosystems, to whole river systems, to the global systems of inland waters. Built on strong collaborations that are national and international in scope, our group also serves as a teaching platform for the next generation of ecosystem and earth system scientists.
