Bray Rivers Lab

Erin Bray is an Assistant Professor in the Department of Earth and Climate Sciences and leads the Rivers Lab at San Francisco State University. Our research focuses on hydrology and fluvial geomorphology, with emphasis on river processes, river restoration, and water resources management. We are interested in river mechanics including sediment transport, river temperature, heat exchange between the water and atmosphere, fluvial abrasion, and hyporheic processes. Our group is also interested in quantifying how environmental change and human activities alter the ways in which rivers and watersheds function. Our research combines field observations, laboratory experiments, analysis, and computational modeling.
