Peter A. Troch

Professor, Hydrology and Water Resources

Agnese N. Haury Endowed Chair in Environment

Science Director, Biosphere 2

Dr. Peter Troch is a surface water hydrologist whose current research involves seasonal, decadal and climate predictions of water availability in semi-arid river basins, as well as developing research infrastructure to investigate Critical Zone processes across climate gradients. He is Science Director of UA Biosphere 2, a member of the editorial board of Hydrological Processes, editor of special issues in Advances in Water Resources and Journal of Hydrometeorology, and was associate editor of Water Resources Research. He has publis­hed over 140 papers in refereed interna­tional jour­nals dealing with (flash) flood forecas­ting, catchment classification and similarity, land slide and debris flow modeling, remote sensing applica­tions in hydrology and data assimilation, climate variability and climate change impacts on water availability, and the role of vegetation on hydrologic partitioning at catchment scales. He has been involved in several international airborne and spaceborne remote sensing experiments in hydro­logy. Dr. Troch is the recipient of the 2011 John Dalton Medal, awarded by the European Geophysical Union for distinguished research in hydrology evaluated as an earth science. Prior to coming to the UA, he was Chair of the Hydrology and Quantitative Water Management group of Wageningen University, the Netherlands.
