Weekly evening meetings to read papers and discuss extreme events.  We are motivated by events in the Front Range in September 2013, but will try to put these in a much broader context.  Guided by interests within the group, we will cover topics ranging from flood hydrology, groundwater recharge, debris flow generation, disturbance effects on ecosystems and sediment systems, magnitude-frequency trade-offs in erosion rates, the legacy of extreme events in the landscape.
