Fluvial Geomorphology of Steep-Gradient Rivers

Image of Current Focus for Fluvial Geomorphology of Steep-Gradient Rivers

My research focuses on processes affecting steep-gradient rivers. I am particularly interested in fluvial geomorphology and hydraulics of mountain rivers. I work on debris flows and the river’s response to debris-flow input and the competence of a river to move large boulders. I am also interested in the long-term evolution of bedrock-controlled rivers as well as the response of the aquatic ecology to different geomorphic settings.
