Ariane Jong-Levinger [engineering graduate student] and colleagues from the University of California, Irvine used stochastic modelling to study the effects that changes in extreme rainfall and wildfires have on flood-protection infrastructure such as flood channels and debris basins in a mountain watershed similar to those found in southern California. They find that more frequent and severe fires lead to more events that exceed the capacity of the protective infrastructure. Read More
