AIH Webinar: Process-Based Quantification of the Role of Wildfire in Shaping Flood Frequency
February 22 @ 9:00 am - 10:00 am PST
Join AIH for this month’s webinar presented by Dr. Guo Yu, assistant research professor at Desert Research Institute and a licensed professional engineer in the state of Nevada.
Webinar Summary: Moderate to high severity wildfire can abruptly alter watershed properties and enhance extreme hydrologic responses such as debris flows and floods. The compounding effects of wildfire on flood hazard, represented here via flood frequency analysis (FFA; e.g., 100-year flood) are of growing importance. Standard statistical FFA approaches are ill-suited to examining this issue because wildfire-affected flood peak observations are limited in number and violate the assumption of independent and identically distributed events. Here, we developed a process-based FFA framework that integrates a stochastic rainfall generator, wildfire simulation, inverse modeling, and a physics-based hydrological model to directly simulate the impacts of wildfire on FFA. We applied this framework in the upper Arroyo Seco watershed in Southern California.
