AB: The IAHS Decade on Prediction in Ungauged Basins (PUB) is a 10 year effort by the international research community to change fundamentally, the practice of hydrology: to focus on uncertainty reduction in all its forms and shift hydrology from the use of calibration reliant models to schemes that can be used without the aid of calibration data. Over the past 5 years, U.S. scientists have helped lead the six main science themes of PUB: development of watershed classification measures, conceptualization of process heterogeneity, development of model uncertainty diagnostics, development and use of new data collection approaches, development of new hydrological theory and development of new model approaches. The PUB science plan has served as a community science exemplar for CUAHSI and the recent USA PUB Workshop has influenced programmatic thinking at NSF. PUB is now formally linked to other international programs where U.S. scientists are playing leadership roles (e.g. UNESCO's HELP and FRIEND programs). PUB has a Secretariat funded by the International Water Management Institute, located in Colombo Sri Lanka. PUB has also launched the Blue Nile initiative where U.S. scientists now have a vehicle for participation in coordinated hydrological science in developing world. Several U.S.-based PUB Working Groups are now underway, including the Slope Intercomparison Experiment, the Low Flow Working Group, the Model Diagnostics Working Group and the Watershed Classification Working Group, among others. This presentation is designed to bring attention to these activities for AGU members who are not aware of them and to foster even greater participation by the U.S. community in this multi-national program.
