Review paper out now in Earth-Sci Reviews

Take a look at our new invited review on how boulders influence landscape evolution, out now in Earth-Science Reviews. We try to synthesize recent progress on this problem and point out directions for fruitful future research. Thanks to coauthors Jens Turowski, Ron Nativ, Rachel Glade, Georgie Bennett, and Bene Dini!

New paper out in GSA Bulletin

Find it here! If some rock units deliver large boulders to rivers through landsliding, but other rock units don’t, does this leave a meaningful imprint on the shape of the landscape? We mapped 1,833 boulders, analyzed topography and landslide inventories, and applied a simple numerical model to understand how lithologically controlled boulder delivery influences landscape response to tectonics. This data-intensive undertaking was only possible thanks to fantastic collaborators Georgie Bennett, Greg Tucker, Kevin Roback, Scott Miller, and Josh Roering!

I’m moving (and recruiting)!

I am thrilled to report that in January 2021 I’ll be joining the Department of Geology and Geography at West Virginia University as an assistant professor.

I’m looking for graduate students to apply this coming fall/winter and start at WVU in Fall 2021. WVU offers MS and PhD Geology degrees in a large, research-intensive department. There’s a great group of faculty with research interests that touch on surface processes, and a great group of friendly and motivated grad students.

Please see this page and/or email me directly for more information!

Three new papers out in JGR: Earth Surface

Which mathematical representation for geomorphic processes best matches a given study site? How can we test agreement or disagreement between models and reality? How should we determine what values to use for model parameters?

Three papers representing the culmination of ~four years of work (led by the indefatigable Katy Barnhart of CU Boulder) on these problems were just published in JGR: Earth Surface. Find part 1, part 2, and part 3.

Paper on river canyons out in Geology

How do feedbacks between rivers and their adjacent hillslopes control the shape and evolution of iconic river canyons? Myself and recently-defended ex-grad-student Rachel Glade did some modeling work to understand how big blocks of rock govern channel-hillslope coupling and canyon shape. Find the paper here.
