College of Idaho students field research experience

This past summer (2016), students at The College of Idaho — Donavan Maude (16′ Biology and Environmental Studies double major) and Natasha Dacic (18′ Math-Physics and Environmental Studies double major) — traveled into the Idaho backcountry to study riverine response to wildfire.

Dissertation: Bedrock river forms and processes

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 river,” was conducted in the Blue Ride province in the southern Appalachian mountains. 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 […]

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

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.

Post-fire debris flows in the Middle Fork of the Boise River

October 10, 2012 2:37 am

John Buffington and I just returned from an 11 day trip to re-survey a one-mile section of the Middle Fork of the Boise River that experienced three simultaneous debris flow inputs following the Hot Creek Fire in 2003. The photo series below (credit: John Buffington) shows the rapid response of the main stem river at the Steel Creek fan. Our surveys continued on a former postdoc project and sediment transport model developed by Mik Lewiki. I won’t go into too many of those specifics here, but stay tuned for the 2012 repeat photo next week.

Middle Fork of the Salmon River, 2012

Mountain Life, Water

September 2, 2012 3:48 pm

“Have I ever told you how much I LOVE my job!?” This phrase may be a little over used in my world, but who cares, it’s true. I was able to book end my summer field work with two float trips down the Middle Fork of the Salmon River, and one trip sandwiched in the middle. So it was a hat trick, a trifecta, a tripple crown. Whatever you prefer to call it, it came in threes: three trips down the river, three different seasons, three different flows, three different purposes all rolled into one – science, adventure, fun. (Actually there are more of the later, but three seemed to fit the theme, so I chose the best ones.) Yes, I love my job (it’s actually better to call it my career and my life, but enough bragging). Here are some highlights from the trips: – I flew into Indian Creek to launch […]
