Hamid Moradkhani, Civil and Environmental Engineering faculty, co-organized a congress technical track titled "Stochastic and Probabilistic Approaches for Analyzing Complex Water Resources Systems" that included 12 technical sessions. He also presented three papers, "Uncertainty Assessment of Water Resources Systems using Data Assimilation and Ensemble Methods," "Toward Improved Hydrologic Prediction with Reduced Uncertainty using Sequential Multi-Model Combination," and "Lessons from Fish Passage Waterways in Oregon and Factors for Improving their Construction" at the World Environmental & Water Resources Congress 2008 in Honolulu, May 12-16. The last paper was co-authored with Sheryle Quinn and Trevor Smith from PSU. At the congress, Moradkhani was elected chair of technical committee on "Probabilistic Approaches in Water Resources Systems" through 2010.
