Research Program: The geographic extent of the Rocky Mountain Research Station includes much of the western US. This landscape is geologically young and dynamic (steep terrain, prone to floods, wildfire, and debris flows), contains abundant resources (water, timber, minerals, recreation), and provides important habitat for many threatened and endangered fish (predominantly salmonids). Within this context, I conduct a broad range of geomorphic studies of watershed processes over multiple spatial and temporal scales, including (1) erosion and sediment transport, (2) genesis and evolution of channel morphology, (3) stream flow and channel hydraulics, (4) exchange of surface and subsurface water (hyporheic exchange), (5) physical and biological interactions in channel, riparian and hillslope environments, and (6) system response to natural and anthropogenic disturbance (e.g., floods, fire, climate change, dams, logging, mining). The overarching goal of this research is to address fundamental problems that have direct relevance for management, conservation, and restoration in mountain basins in the western US and abroad. Toward this end, a combination of field, laboratory, and numerical studies (computer models) are used to address basic and applied problems in collaboration with a diverse group of peers.
• Effects of climate change on channel morphology and salmonid habitat across different hydrologic regimes (snowmelt, rainfall, transitional) in northern basins (western US and Scotland)
• Geomorphic controls on salmonid habitat at watershed scales • Effects of post-fire debris flows on channel morphology and aquatic habitat
