Description:
This 45-minute lesson introduces the learner to the 2018 Spring Creek Fire burn scar in Colorado and the assets threatened by potential flooding and debris flow events in the area. Next, the learner takes on the role of a forecaster exploring three different rainfall events to evaluate the factors conducive for a flash flood and debris flow event in relation to the burn scar. In each event, the learner is supported by feedback from the Burned Area Response Team, Service Hydrologist and operational forecaster colleague on what aspects are most important to consider in the situation. Following the exercises, learners can view a model simulation of a realistic post-wildfire flash flood and debris flow event that impacted Glenwood Canyon in Colorado.
Objectives:
1.Weigh the four factors that are key to monitor for potential flash floods and debris flows in post-wildfire burn areas:
(1)Soil burn severity across the landscape
(2)Drainages across the landscape
(3)Potential for heavy rainfall
(4)Potential to meet or exceed the rainfall rate threshold
2.Use geological, hydrological and meteorological data to evaluate conditions for a potential flash flood and debris flow event in a post-wildfire environment
3.Identify the contributions made by of the Burned Area Emergency Response (BAER) Team, hydrologists and forecasters in assessing the potential for flash flood and debris flow events in a post-wildfire burn area
