Wildfire Effects on Water Resources, Natural Hazards, and Ecosystems

Session ID#: 85495

Session Description:
This session invites research contributions that showcase wildfire effects on hydrologic, geomorphic, biogeochemical, and ecological processes. Wildfires that remove vegetation and change soil physical and chemical properties can lead to changes in precipitation reaching the soil surface, soil moisture, streamflow, erosion, and probability of mass movements. Moreover, wildfires can alter the surface energy balance, with additional effects on snow accumulation, snowmelt, and nutrient fluxes. Wildfire may also cause shifts in vegetation that impacts hydro-ecological processes. Given the wildfire regime shifts in many regions of the world, it is increasingly important to advance our understanding of wildfire effects to inform management decisions and mitigation strategies. We encourage contributions from short- and long-term studies, empirical and modeling efforts, and interdisciplinary research. These contributions may include early warning systems, decision support tools, communication efforts, and analyses of post-fire remediation and restoration strategies. This session particularly encourages contributions that celebrate the AGU's Centennial.
