Pyrogeomorphology: landscape response following wildfire
Session ID#: 85559
Session Description:
Wildfires transform landscapes by accelerating rates of runoff and erosion, as well as rapidly redistributing sediment and pyrogenic debris. Due to climate change and, in some ecosystems, the accumulation of fuels due to fire suppression, wildfire regimes have significantly changed over the past few decades. Ongoing increases in burned area and severity are projected to enhance pyrogeomorphic impacts to downstream life, infrastructure, and ecosystems. This session specifically highlights research focused on pyrogeomorphic responses, including but not limited the alteration of water, sediment, or carbon fluxes, throughout landscapes and across a range of temporal scales. Particular emphasis will be given to work that considers post-wildfire effects at the watershed-scale or that addresses the cumulative impacts of wildfire to Earth surface processes over geologic time. We also encourage submissions that represent the breadth of current research on pyrogeomorphology, including field and laboratory studies, remote sensing, and advances in numerical modeling.
