Tectonic geomorphology: Adaptation of drainage to tectonic forcing

Research areas: Tectonic Geomorphology, Fluvial Geomorphology, Landscape evolution, Geochronology

Principal investigators: Dr. Steven Binnie, Prof. Dr. Klaus Reicherter, Dr. Pia Victor

This project aims to investigate how tectonic uplift has influenced drainage evolution in northern Chile. Surface displacement due to faulting can reroute and force reorganization of stream networks. This process has been shown to be prevalent throughout northern Chile, where relatively minor amounts of fault slip can result in channel avulsion. We propose to utilize both established and novel geochronological techniques to date stream channel diversions at multiple fault sites throughout the Atacama Desert.

This will be combined with surface and subsurface imaging of the fault structures allowing us to develop chronologies that help better understand the interactions between fault displacement and drainage reorganization and how fast the landscape is reacting to these changes. The central question is whether the apparent pulses of tectonic drainage reorganization are related to tectonic uplift alone, or whether climatic shifts are also responsible.
