 [‘water cut’ by mary bourne. commissioned by eccp for the eden benchmarks collection]




Christa Kelleher was one of the 10% of EPA STAR Fellows chosen to present their work at Capitol Hill, Washington DC, and was awarded a CUAHSI Pathfinder Fellowship for field work at Montana State University.

MOCHA was given the 2011 Education and Public Service in Water Resources Award by the US Universities Council for Water Resources (UCOWR). The award is given to recognize educational institutions, individuals, groups, or agencies that have made significant contributions to increased public awareness of water resources development, use, or management covering any one or a combination of the natural, biological, and social sciences.

The Best Paper Award 2009 of the Journal Environmental Modeling and Software in the Category Integrated Modelling was awarded to a group of researchers including Thorsten Wagener for their paper A formal framework for scenario development to support environmental decision making [PDF]. This paper reviews the state-of-the-art of scenario development and proposes a formal approach to scenario development in environmental decision-making. The discussion of current issues in scenario studies includes advantages and obstacles in utilizing a formal scenario development framework, and the different forms of uncertainty inherent in scenario development, as well as how they should be treated.

Christa Kelleher has been awarded a 2010 EPA STAR Graduate Fellowship (http://www.epa.gov/ncer/fellow/).

Thorsten Wagener has been given one of the 2010 Walter L. Huber Civil Engineering Research Prizes by the American Society of Civil Engineers (http://www.asce.org/AwardsContent.aspx?id=21723).

Thorsten Wagener has been awarded a Humboldt Research Fellowship by the German Alexander von Humboldt Foundation in 2010. The fellowship will fund research collaborations with European researchers over a period of three years (http://www.humboldt-foundation.de/web/home.html).

Our Research

Hydrology deals with the movement and storage of water in complex environmental systems in which humans are important actors. A systems approach is needed to properly advance the science of hydrology and to achieve water security for people and for nature. Our group uses systems methods to advance hydrologic theory and to build and evaluate predictive models for sustainable water management. Particular current interests are predictions in ungauged basins, uncertainty in hydrologic modeling, catchment classification, and scenario analysis.

A basic assumption in all our efforts is that education and research are inherently related and cannot be treated separately. Current educational interests include the development of case studies for water resource engineering and the use of new technology like tablet PCs and student response systems in the classroom.

We are always looking for highly motivated graduate students and postdocs to join our group. If any of the above topics (both research and education) interest you, then please contact us.
