Summary
👤
Senior🎓
Top SchoolMichael Koohafkan is a River Mechanics Subject Matter Expert and water resources engineer with 13 years of experience applying hydrodynamics, sediment and contaminant transport, and water quality science to flood risk management and reservoir operations across the Columbia and Willamette basins. He combines a PhD in Hydrologic Sciences (UC Davis) and an MS from UC Berkeley with deep hands-on modeling and software development skills—Python, R, FORTRAN, GIS/ArcPy—and a track record of translating large-scale data and remote sensing into operational decision tools. At USACE and prior state agencies he has led sediment transport, spill-risk, and estuary dynamics projects, developed operational models and toolboxes adopted for habitat and emergency response, and delivered technical leadership for international treaty work. His research includes novel graph theory methods for tracking geomorphic features from imagery, and he’s built high-volume pipelines for AIS vessel simulation and physics-based drift modeling—an uncommon blend of geomorphology, statistics, and applied software engineering. Based in Portland, he brings both academic rigor and practical delivery to complex river and estuary systems.
