Dr. Yager joined the Center of Ecohydraulics Research and the Department of Civil Engineering in the Fall of 2007.

Her research interests focus on gaining a mechanistic understanding of the interactions between flow turbulence, sediment transport and river morphology. She uses field and laboratory experiments to elucidate the processes that control flow and sediment flux on hillslopes and in river channels. This knowledge is then used to improve predictions of flow and sediment flux throughout river systems. An understanding of sediment transport is particularly important in areas impacted by increased fire severity and human activities (e.g. logging, grazing, mining, dam removal, or construction).

Dr. Yager is actively collaborating with researchers at Arizona State University, University of California, Berkeley, and the Swiss Institute WSL.
