Dr. Julien is a Registered Professional Engineer with more than 40 years of experience in the field of sediment transport and river engineering. He developed state-of-the-art computer models in hydrology and hydraulics for the simulation of water, sediment and contaminant transport at the watershed scale. He improved sediment transport calculations in rivers with fast numerical solutions of the Einstein integrals. He contributed to the analysis of sedimentation in reservoirs, river dynamics and local scour. He completed projects for more than 50 different professional organizations and governmental agencies including the World Bank, the Nuclear Regulatory Commission, the US Army Corps of Engineers, the US Bureau of Reclamation, and the US Environmental Protection Agency. He was a speaker and moderator at the World Water Forum and served as Editor of the ASCE Journal of Hydraulic Engineering. He delivered more than 25 keynote addresses at International Conferences.
