Presentations at AGU Fall Meeting 2022

I can’t believe it’s already time for AGU Fall Meeting! I will be there all week. On Tuesday, I have a poster on DupuitLEM, the groundwater-landscape evolution model that I developed for my doctoral work. I talk about the model itself, and also some more general considerations for coupling processes that operate on very different timescales. On Thursday I have a talk that focuses on some of the hydrological implications of my work with this model. We show how variable source areas emerge when changing subsurface properties and climate, and how ultimately the relationship between topography and landscape morphology described in the Dunne Diagram (Dunne 1978) emerges as a result of coevolution. Lots of exciting work going on here, and a lot more to be done before we fully understand this.

I’m also a co-author on several presentations that are re-examining classic trenched hillslope at Panola Mountain research watershed (of fill-and-spill runoff generation fame) in light of new geophysical datasets collected by the Bedrock Critical Zone Collaborative Network, including one by Sam Motz, who I co-supervised this summer as an REU student. Looking forward to seeing you there!
