Climate Change Effects on Salmon Habitat

In this research we investigate how climate-driven changes in streamflow will alter the physical habitat for salmonids in mountain basins of different regions and hydroclimates. We explore the potential consequences for the incubation period of different salmonid species. Watersheds in northern latitudes provide critical habitat for salmon and trout, and many species are adapted to the streamflow frequency, magnitude and timing of flows that can scour incubating embryos. Therefore, climate-related shifts in the flow regime are expected to influence the the early life stages of these species.

Dynamics of sediment transport in stream potholes

    Rivers carved into bedrock often display elegant sculpted features, such as potholes, reflecting processes of erosion. We are investigating the sediment transport dynamics of the gravel-sized tools potentially responsible for erosion (formation and maintenance) of these forms. These experiments were conducted this past winter at the Center for Ecohydraulics Stream Laboratory. Collaborators: Dr. Elowyn Yager (University of Idaho) and Dr. John Buffington (US Forest Service, Rocky Mountain Research Station)

Aquatic Habitat Modeling

In my postdoc at the University of Idaho, I am working on a side project led by Dr. Daniele Tonina in the Lemhi River, Idaho. The work aims to compare 2-D numerical modeling results based on two different topographic mapping methods: 1) ground-based surveys using an RTK GPS, and 2) a new terrestrial-aquatic LIDAR. The photos document our recent field survey.
