Ryan Morrison, Associate Professor, Colorado State University

I am a water resources engineer and Associate Professor at Colorado State University in the Civil and Environmental Engineering Department. My research interests include hydrodynamic interactions in river-floodplain systems, large-scale human impacts to river corridors, fluvial responses to wildfire and flood disturbances, and responses of headwater streams to process-based restoration.
