SUMMARY:Data and computational advances in the fight against floods\, 
 Chaos & Complex Systems Seminar\, Dan Wright\, UW Department of Civil 
 and Environmental Engineering
DESCRIPTION:Recent decades have seen a substantial increase in the num
 ber and severity of rainstorms in Wisconsin and elsewhere. This increa
 se is driven by global warming\, and is likely to continue into the fo
 reseeable future. Many logically assume that floods are also becoming 
 worse as a result. In this seminar\, we’ll see that the story is mor
 e complicated. Some human actions have had clear impacts on floods—u
 rbanization\, for example\, significantly exacerbates flooding\, while
  dams and reservoirs are able to mitigate these risks to some extent. 
 Advances in weather forecasting have reduced flood-related fatalities\
 , but economic growth has greatly increased the overall economic risks
  from flooding. When it comes to climate change impacts on floods\, th
 e story is complex and not well understood. The reason for this is tha
 t floods are “recipes” that consist of multiple ingredients—not 
 just rain but also land cover\, soil moisture\, snow\, and river prope
 rties. We will discuss what we know and don’t know about how these i
 ngredients are changing\, and see several recent examples of how new d
 ata and tools can be brought to bear to understand the complex relatio
 nships between rainfall\, floods\, and how they are co-evolving in a c
 hanging Wisconsin.
