Flash Flooding - Ways That Science and Adaptation Reduce Losses

Abstract:

Flash flood vulnerability is increasing. Predictability is more difficult as more flooding results after wildfires destroy hillside vegetation. Recent extreme events have occurred outside of seasonal norms with well beyond expected precipitation rates, and with unusual storm behavior where precipitation rates increase at the end of a storm. Engineers, social scientists, physical scientists, planners, emergency managers and others must collaborate in new ways to keep losses from rising. For example improved detection using cameras and gages must be complemented by understanding why people drive through flooded roads and what can be done to reduce the number of people on flooded roadways. Case studies of successful collaborations will be provided along with discussion of challenges and opportunities for expanding the innovative flash flood risk reduction strategies.
