Congratulations to Keith Sawicz and Christa Kelleher for passing their Masters theses defenses on the topics of catchment classification and temperature elasticity regionalization respectively in 2009. Both will continue for their PhDs at Penn State.

The Best Paper Award 2008 of the Journal Environmental Modeling and Software in the Category Integrated Modelling was awarded to Yuqiong Liu, Hoshin Gupta, Everett Springer and Thorsten Wagener for their paper Linking science with environmental decision making: Experiences from an integrated modeling approach to support sustainable water resources management [PDF]. In this paper the challenges involved in bridging science and decision making in water resources management are discussed with reference to lessons drawn from a long term integrated modeling project in the semi-arid southwestern USA. The authors present a generic framework and guidelines for effective decision support using integrated modeling and scenario analysis. The proposed approach aims to produce ‘usable’ scientific information, by improving its credibility, legitimacy and saliency for decision support.

Katie van Werkhoven has been selected as the first place recipient of the US Universities Council for Water Resources (UCOWR) 2009 Ph.D. Dissertation Award in the field of Natural Science and Engineering. Katie graduated from Penn State with a Ph.D. in Civil and Environmental Engineering in August 2008 with a dissertation titled Evaluating model behavior for hydrologic forecasting in gauged and ungauged watersheds. Katie lives and works in Phoenix with her husband and her recently born son.

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.
