My PhD thesis work focuses on the erosion of rivers that experience the delivery of large blocks of rock from adjacent hillslopes (Shobe et al., 2016, GRL; Shobe et al., submitted, JGR-ES). Such landscapes require two conditions to form, both of which are controlled by tectonics. First, the underlying bedrock must be pervasively fractured. Second, the channel must be eroding rapidly enough to steepen hillslopes and allow block delivery. Tectonic stresses control fracturing of rock, and tectonic uplift relative to baselevel sets long-term rates of river erosion. As such, tectonic processes govern the two boundary conditions for block-influenced river channels. My numerical models of channel evolution do not include physically-based descriptions of these processes, but I am interested in learning how to potentially implement tectonic forcings into my models. Attending the CTSP workshop would allow me to learn the newest approaches to modeling tectonic processes.</br></br>Attending the workshop would allow me to progress on other work as well. I have recently developed a model for the long-term evolution of bedrock-alluvial rivers (Shobe et al., in press, GMD), and am looking for ways to use this model to test two-way feedbacks between fluvial erosion and tectonics (e.g., the connections between fluvial sediment transport, lithospheric flexure, and landscape evolution). Meeting other attendees with far more expertise in these areas than I have will help me focus my efforts on the most salient problems.s my efforts on the most salient problems. +
