    Dissertation: Bedrock river forms and processes

    Key Findings 1) Feedbacks between substrate, channel morphology and hydraulics reflect balance between hydraulic driving forces and substrate erodibility. 2) Lithologically controlled bed forms in bedrock streams (bedrock ribs) influence sediment transport at potentially smaller scales than bed forms in alluvial channels. The strong influence of bedforms on coarse sediment transport suggested that coarse sediment transport processes are controlled by different factors in bedrock channels when bedrock ribs cross the channel at a high angle to the flow. 3) The tools versus cover effect represents intra-reach variation and can be used to quantify how flow and sediment transport interact with bed topography to maximize pothole formation. Constraining thresholds governing pothole formation will improve understanding of fundamental processes underlying bedrock channel erosion and landscape evolution.   I completed my doctorate in Geosciences, specializing in fluvial geomorphology, at Colorado State University in May 2009. My dissertation entitled, “Substrate controlled interactions among hydraulics, sediment transport and erosional forms in a bedrock […]

    Increased sediment delivery in mountain basins in a warming climate

    Sediment delivery and transport through mountain rivers affects aquatic habitat and water resource infrastructure. This research synthesized existing data from central Idaho to explore (1) how sediment yields are likely to respond to climate change in semi-arid basins influenced by wildfire, (2) the potential consequences for aquatic habitat and water resource infrastructure, and (3) prospects for mitigating sediment yields in forest basins. In the northern Rocky Mountains, sediment yield is expected to increase in a warming climate primarily through climate-driven changes in temperature and hydrology that promote vegetation disturbances (i.e., wildfire, insect/pathogen outbreak, drought-related die off).

    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

    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.

Fluvial Geomorphologist

Idaho offers an ideal setting to explore many of my research interests, while keeping the mind fresh with endless opportunities for mountain adventure and intellectual inquiry. I currently work as a postdoctoral fellow at the Center for Ecohydraulics Research, University of Idaho, where I work jointly with the US Forest Service, Rocky Mountain Research Station on research related to climate change and physical and ecological processes in mountain river systems.
